This article discusses the inadequacy of 5 vegetable oils as substitutes, as well as the characteristics of 22 D-limonene-based substitutes, all less effective in their chemical role, some capable of inducing health problems, and costing more than twice as much as xylene. Some of the 35 alkane-based substitutes discussed are effective for tissue processing, less toxic, with a cost about the same as xylene, but are not very effective for dewaxing and other staining tasks. Isopropanol (2-propanol) alone or mixed with molten paraffin is a technically acceptable and cost-effective substitute for xylene for tissue processing, but in this study, we demonstrate that the best clearing agents from the sectioning quality and diagnostic value point of view, with automated or manual protocols, are mixturesof 5:1 and 2:1 isopropanol and mineral oil, followed by undiluted mineral oil, all at 50 degrees C, making thema safer and cheaper substitute than xylene. Using a1.7% dishwasher soap aqueous solution at 90 degreesC to dewax before staining and oven drying the stained sections before coverslipping will eliminate xylene from the staining tasks. Tissue processors retorts and conduits can be dewaxed with a 2% solution of a strong glassware laboratory detergent. These 4 methodologies will make the histology laboratory xylene-free but, due to the natural resistance to change, many histotechs will be reluctantto adopt them if they think that their technical expertise could be jeopardized, and the only way these changes will succeed is if the pathologists, as stewards of the histologylaboratory, commit to their implementation.Go Greener Histology & HematologySigma-Aldrich® is Committed to Bringing Safer Greener Alternatives to Our Customers.• Novec fluids are non-flammable, low toxicity fluidsfor freezing histology samples.• Xylene Substitute is non-toxic version of xylenewhich is compatible with all tissue• Formalin Free Tissue Fixatives is a less toxicalternative to formalin. It is also compatible witha number of applications like PCR, IHC and in-situhybridization• HistoChoice® Clearing Agent is suitable as analternative to toluene and xylene for dewaxing paraffintissue sections• HistoChoice Tissue Fixative is designed for molecularbiology and used for in-situ hybridizationThe life science business of Merck operates asMilliporeSigma in the U.S. and Canada.Formalin Free Tissue FixativesM E Boon and L P KokBiotechnic and Histochemistry, 83(6), 261-277 (2008)The German, F. Blum, introduced formalin as a fixative in 1893. Formalin rapidly became popular for hardening and preserving gross human and animal specimens. As a result, microscopy for diagnostic pathology by combining paraffin embedding and formalin fixation was developed. Alcohol-based fixatives have coagulation of proteins as their main preservative effect. Because there is no cross-linking, immunostaining is not compromised, and DNA and RNA is not damaged. Ethyl alcohol was used by Dutch scientists of the 18th century, but was replaced by the cheaper formalin. Addition of low molecular weight polyethylene glycol (PEG) optimized the coagulant fixative, Kryofix. The polyethylene glycol prevents excessive hardening and enhances the speed of coagulation of proteins. Kryofix was used on a large scale for skin biopsies in Leiden between 1987 and 2001. DNA preservation by the formulated coagulant fixative, BoonFix, is related to the concentration of ethyl alcohol, PEG and acetic acid. BoonFix has been used since 2004 in Leiden for over 40,000 diagnostic skin biopsies and more than 100,000 cervical samples.A literature review and three decades of experience with coagulant, formalin-free fixatives in pathology suggest that when health authorities realizethat formalin invalidates expensive tests, it might eventually be eliminated legislatively from diagnostic pathology. Finally, coagulant fixation is optimal for microwave histoprocessing where ethyl alcohol is followed by isopropanol. HistoChoice® Clearing Agent1. I mmunogenicity and contraceptive potential of three infertility-relevant zona pellucida 2 epitopes in the marsupial brushtail possum (Trichosurus vulpecula).Janine A Duckworth et. alReproduction, 133 (1), 177-186 (2007)In a previous study, three infertility-relevant epitopes of possum ZP2 (Pep12 (amino acids 111-125), Pep31 (amino acids 301-315), and Pep44 (amino acids 431-445)) were identified using sera from possums (Trichosurus vulpecula) immunized with recombinant possum zona pellucida 2 (ZP2) constructs, and a synthetic peptide library of possum ZP2 protein. In this study, the three peptides were conjugated to keyhole limpet hemocyanin and 300 mug of each conjugated peptide were administered subcutaneously to female possums (n = 20 per peptide) in complete Freund's adjuvant. Immunogen doses were repeated 3 and 6 weeks later using incomplete Freund's adjuvant. Control animals were immunized with either phosphate-buffered saline only (n = 10) or 300 mug keyhole limpet hemocyanin (n= 10), administered with the same adjuvants. Serum antibodies from animals immunized against these three epitopes bound to the corresponding possum ZP2 peptides, recombinant possum ZP2 protein constructs, and native zona. Possum fertility was assessed following superovulation and artificial insemination. Peptides Pep12 and Pep31 had no significant effects on fertility parameters (P > 0.05). However, animals immunized with Pep44 had lower egg fertilization rates (immunized 19.5% versus control 60.5%,P < 0.05) and produced significantly fewer embryos than control animals (immunized 0.5 embryos versus control 2.4 embryos, P < 0.05). The number of Pep44-immunized females that produced embryos was reduced by 64%. Identification and characterization of possum infertility-relevant epitopes on possum ZP2 protein will assist development of safe, humane, and possum-specific immunocontraceptive vaccines for controlling the introduced possums in New Zealand.2. A simplified method for combined immunohistochemistry andin-situ hybridization in fresh-frozen, cryocut mouse brain sections. Sathyanesan Samuel Newton et. alBrain Research Protocols, 9 (3), 214-219 (2002)A method is described to perform combined immunohistochemistry and in situ hybridization in mouse brain sections. The protocol is specific to sections mounted on glass slides. In contrast to earlier methods that require either paraffin embedding or perfusion ofthe brain with paraformaldehyde, this protocol can be carriedout on fresh-frozen, cryostat cut post-fixed sections. This simple and concise protocol increases the applicability of the techniqueas the RNAse-free immunodetection of antigen is useful by itself for immunologically identifying specific cells of interest and then examining gene expression in those cells using techniques such as real-time PCR and microarray analysis. The use of fresh-frozen, cryocut sections enables reliable detection of easily perturbable post-translational modifications such as phosphorylation and improves the quality of results obtained in subsequent in situ hybridization by reducing the background signal and interference from lower cell layers. Inducible transgenic mice that express either a dominant negative mutant form of the cAMP response element binding protein (mCREB) or CREB, in discrete brain regions, were used in this study. The combined immunohistochemistry and in situ hybridization protocol was used to examine colocalization of enkephalin or dynorphin mRNA, both downstream targets of CREB-mediated gene expression, in cells expressing transgenic mCREB or CREB. HistoChoice Tissue FixativeJ Melrose et. alBiotechnic and Histochemistry, 83(1), 47-53 (2008) Histochoice is a proprietary nontoxic, non-cross-linking fixative designedby the manufacturer to replace formaldehyde based fixation protocols. We compared Histochoice and formalin fixation for several cartilaginous tissues including, articular and growth plate cartilage, meniscus and intervertebral disc. The tissues were stained with general histology stains including toluidine blue for tissue proteoglycans, picrosirius red to evaluate collagenous organization, and hematoxylin and eosin to assess cell morphology. The chondroitin sulfate and heparin sulfate substituted proteoglycans aggrecan and perlecan were also immunolocalized in some of the tissues to provide a comparison. Histochoice did not fix deep into the tissue blocks resulting in focal loss of aggrecan and other matrix components from the more central regions of the blocks. This was evident in toluidine blue stained sectionsof immature tibial articular cartilage where loss of glycosaminoglycan was significant in Histochoice fixed tissues. Histochoice fixation worked well, however, in the aggrecan and perlecan immunohistology applications where its non-cross-linking traits were conducive to epitope retrieval and identification by primary antibodies to extracellular matrix components.To place an order or receive technical assistance Order/Customer Service: /orderTechnical Service: /techserviceSafety-related Information: /safetycenter Copyright © 2017 Merck KGaA.

3M Friction Shims 产品说明说明书
3M Advanced Materials DivisionIntroductionThe demand for maximum powerdensity, i.e. the transmission of greater force and torque in increasingly compact designs, poses a major challenge to engineers across a variety of industries. 3M Technical Ceramics manufactures friction-enhancing solutions for joining components to withstand highershear forces or transmit higher torque in bolt connections. 3M ™ Friction Shims offer a simple and cost-effective way to reliably transmit up to 4x higher torques or forces thanconventional systems without requiring modifications to the joint design.3M friction shims are metal foils with a coating of electroless nickel embedded with diamond particles. The diamonds indent into the metal mating surface and create a micro-scale interlock. The shims themselves are easy to assemble and can bereused after disassembly. 3M friction shims are thin enough to fit within close engineering tolerances, creating possibilities for lightweight compact design while increasing maximum load and peak torque in bolt connections.3M friction shims have proveneffective in a wide variety of industries, including general mechanicalengineering, machine tools, marine engineering, wind and water power generators, turbines, automotive engineering and motor sports. Our technical specialists have many years of application experience, and conduct in-house laboratory and bench tests to ensure that 3M friction shims meet our customers’ specific requirements.Features• I ncreases the coefficient of static friction• F unction of 3M friction shims is not affected by an oil film • Can be easily retrofitted • Prevents fretting • Highly reproducible • C olor option for distinctive appearance• S him geometries can be tailored to customer specificationApplication• Frictional joints • Flange joints• Joints with central bolt • Bolt connections • Fastener systemsApplication NotesWhen 3M friction shims are used please note:• F or maximum performance, the mating surfaces must have roughness values Rz as given in the technical data sheet.• C ontact pressure of at least 50 MPa is recommended.• W hen designing the joint,ensure that the counterparts to be joined are in full contact.• O nly use in applications with static friction in the contact area.• T he coefficient of static friction depends on a large number ofdifferent parameters.

3M Petrifilm Coliform Count Plate说明书
InterpretationGuideThe 3M™ Petrifilm™ Coliform Count Plateis a sample-ready-culture medium system which contains modified Violet Red Bile nutrients, a cold-water-soluble gelling agent and a tetrazolium indicator that facilitates colony enumeration.2Coliform Count PlateTotal colonies with gas = 69 Total colonies = 94The definition of coliforms may vary by country. Please refer to section above and product instructions for definitions.Figure 1No growth = 0Notice the changes in gel color in Figures 2–5. As the coliform count increases, the gel color deepens.Background bubbles are a characteristic of the gel and are not a result of coliform growth.Figure 2The United States Food and Drug Administration (FDA) Bacteriological Analytical Manual (BAM) defines coliforms as Gram negative rods, which produce acid and gas from lactose fermentation. Coliform colonies growing on the 3M ™ Petrifilm ™ Coliform Count Plate produce acid, which causes the pH indicator to deepen the gel color, and gas trapped around red colonies. In this interpretation guide, the number of coliforms per the FDA BAM definition is the number of red colonies with gas.ISO defines coliforms by their ability to grow in method-specific, selective media. ISO method 4832 enumerates typical coliform colonies on Violet Red Bile Lactose (VRBL) agar, with confirmation of atypical colonies. On the 3M Petrifilm Coliform Count Plate, these coliforms are indicated by red colonies with or without gas production. ISO method 4831, enumerating coliforms by the most probable number (MPN) method, defines coliforms by their ability to grow and produce gas in the conditions described in the standard. On the 3M Petrifilm Coliform Count Plate, these coliforms are indicated by red colonies with gas.It is also possible to enumerate thermotolerant coliforms on the 3M Petrifilm Coliform Count Plate. Typically thermotolerant coliforms can be selected with an elevated incubation temperature. One example of a method for enumeration of thermotolerant coliforms is described in NF V08 060. Reading the total of red colonies on a 3M Petrifilm Coliform Count Plate incubated at 44°C ± 1°C for 24h ± 2h yields results equivalent to enumeration with NF V08 060.Coliform Definitions by MethodFood and Beverage ApplicationsPlease refer to theproduct instructions for additional information.3Total colonies with gas = 79 Total colonies = 109The recommended counting limit on 3M Petrifilm Coliform Count Plates is less than 150.Do not count colonies that appear on the foam barrier because they are removed from the selective influence of the medium (see Circle 1).1Figure 3Total coliform count = TNTC3M Petrifilm Coliform Count Plates with colonies that are too numerous to count (TNTC) have one or more of the following characteristics: many small colonies, many gas bubbles, and a deepening of the gel color.For a more accurate count, further dilution of sample may be necessary.Figure 5Estimated total coliform count = 220The circular growth area is approximately 20cm 2. Estimates can be made on plates containing greater than 150 colonies by counting the number of colonies in one or more representative squares and determining the average number per square. Multiply the average number by 20 to determine the estimated count per plate. For a more accurate count, further dilution of sample may be necessary.Figure 4Total count = TNTCWhen high numbers of non-coliform organisms such as Pseudomona s are present on 3M Petrifilm Coliform Count Plates, the gel may turn yellow.For a more accurate count, further dilution of sample may be necessary.Figure 64Total colonies with gas = 2 Total colonies = 2Food particles are irregularly shaped and are not associated with gas bubbles.Figure 7Total colonies with gas = 8 Total colonies = 15Bubble patterns may vary. Gas may disrupt the colony so that the colony “outlines” the bubble (see Circles 1 and 2). Artifact bubbles may result from improper inoculation or from trapped air within the sample. They are irregularly shaped and are not associated with a colony (see Circle 3).123Figure 8Bottled Water ApplicationsColiform colonies are indicated by red colonies associated with gas for bottled water samples plated to 3M Petrifilm Coliform Count Plates.Coliform count: 0Gas bubbles surrounding filter do not indicate microbial growth. See circle for example.Figure 1Coliform count: 0Red colonies without closely associated gas bubbles may be coliforms and should be picked and tested with appropriate confirmation methods.Figure 25Coliform count: 10Figure 4Coliform count: 3Coliforms produce acid (faint pink halo associated with colonies) and are associated with gas bubbles.Figure 3ABCColiform count: 30Gas bubbles may influence colony morphologies. The colony in Circle A is distorted by the gas bubble. In Circle B, a faint colony is underneath the gas bubble. Note large artifact gas bubble in the center of the plate (Circle C).Figure 5Store unopened pouches of plates at<8°C (<46°F). Use before expiration dateon package.

3M TM Attest TM ProductsSterile U Network T U T O R I A L SQuality Control for Table-top Steam Sterilizers Introduction:Many health care professionals in office-based settings are not aware that they are subject to the same standards and guidelines as hospitals and surgery centers. The AAMI Comprehensive guide to steam sterilization and sterility assurance in health care facilities (ANSI/AAMI ST79:2006/A1:2008/A2:2009)1 covers all health care facilities that perform steam sterilization including clinics and dental offices that use a table-top sterilizer. ST79is a consolidation of five previous standards, including ANSI/AAMI ST42 Steam sterilization and sterility assurance using table-top sterilizers in office-based, ambulatory-care medical, surgical, and dental facilities.What is a table-top steam sterilizer?AAMI ST79 defines a table-top steam sterilizer as a compact steam sterilizer with a chamber volume of not more than 2 cubic feet. Most table-top sterilizers generate their own steam within the chamber; distilled or deionized water is added by the user. For steam of acceptable quality the sterilizer manufacturer’s instructions must be followed regarding water purity requirements, filling and draining the reservoir, and general equipment cleaning and maintenance. Manufacturers generally “recommend distilled or deionized water to help prevent mineral buildup in the steam generating system and to ensure the purity of the steam generated for sterilization.”1How do they work?The majority of table-top sterilizers are gravity-displacement units but at least one model has dynamic-air-removal functions.2 During the fill cycle of a gravity-displacement table-top sterilizer, water is released from the reservoir into the sterilizer chamber where it is electrically heated and vaporized into steam. After the sterilization cycleis completed, a condensation coil converts steam back into water. Some models are fully automatic and cycle through ‘fill, sterilize, exhaust and dry cycles’ but many require manual operation to move through the cycles. After the sterilizing cycle is completed, the door is opened slightly to allow moisture to escape and the dry cycle starts. Automated sterilizers have self-diagnostic software and use display codes to assist in troubleshooting. Trays and racks hold peel packs, cassettes and instruments away from the sterilizer sides and bottom.3 Manufacturers Pelton & Crane, Tuttnauer, Midmark/Ritter and SciCan have the majority of units in operation in the US.4Frequently Asked Questions:1. What monitoring tools should be used for table-top steam sterilization cycles?All steam sterilizers used for reprocessing of patient care items, including table-top steam sterilizers inoffice-based locations, should be routinely monitored with a variety of monitoring tools including physical monitors, chemical indicators (CIs), biological indicators (BIs), and process challenge devices (PCDs).Physical MonitorsPhysical monitors are the charts, gauges and printouts on the equipment that provide real-timemeasurements of time, temperature, and pressure. Physical monitors verify that the parameters of thesterilization cycle have been met and tell the operator whether or not the sterilizer is doing its job properly.After each cycle, a trained and knowledgeable operator should read and initial the cycle printout to verify that all cycle parameters were met.Some table-top sterilizers in office-based settings show the measurements from the physical monitors ona digital display but do not have recording devices (e.g., printout) that provide a permanent record.“Sterilizers that do not have recording devices should not be used,” according to section 10.5.1 of AAMI ST79.1 Physical monitoring is needed to detect malfunctions as soon as possible, so that correctiveactions can be taken. This is the first step in stopping the use of medical devices that may not be sterile.External and Internal Chemical IndicatorsExternal CIs are Class 1 process indicators used for Exposure Control to distinguish processed fromunprocessed medical devices at a glance. Indicator tape is an example of an external CI. AAMI ST79recommends that an external CI should be used on the outside of each package unless the internal CIis visible. If the external CI is not changed, the package should not be used.Internal CIs are used for Pack Control and verify that steam penetrated to the location of the instruments inside each package. AAMI ST79 recommends that a Class 3, 4 or 5 internal CI be placed in eachpackage in the area least accessible to steam penetration, which may or may not be the center of thepackage.1 The results of internal CIs should be interpreted by trained and knowledgeable health careprofessionals at the point of use before the items are used for patient care. If the internal CI does notshow an acceptable result, the items in the package should not be used.Paper-plastic peel pouches are a common packaging material used in table-top steam sterilizers. If the internal CI in a paper-plastic peel pouch is visible, then an external CI is not needed. However, if a paper- plastic peel pouch is pre-printed with a Class 1 external CI, a Class 3, 4 or 5 internal CI is still needed.Biological IndicatorsBiological indicators (BIs) contain live spores that are highly resistant to the sterilization process andprovide information about the lethality of the sterilization cycle. They are used in PCDs (i.e., test packsor challenge packs) for the purpose of Load Control. The BI PCD is placed in the most challenginglocation in the sterilizer with a full load and provides information about the efficacy of the sterilizationcycle. Routine sterilizer efficacy testing with a BI PCD is recommended weekly, preferably daily, andwith all implant loads. Implants should be quarantined until the result of the BI is known.2. How is routine BI testing conducted in a table-top steam sterilizer?Biological indicator testing of a table-top sterilizer is conducted in a fully loaded chamber. The BI PCDshould be representative of the load contents and placed in the “cold point” or area least favorable tosteam sterilization. This area is typically the center of the load toward the front of the chamber but varies with sterilizer design; therefore, the manufacturer of the sterilizer should be consulted about placement of the BI PCD. All different cycle types used should be tested. For example, if a table-top sterilizer is used to run cycles at both 250°F and 270°F, then both of these cycles should be routinely tested with a BI PCD.3. Can a pre-made commercially available FDA-cleared BI test pack be used to monitor a table-top steam sterilizer?Since there are no commercially available BI PCDs designed for table-top sterilizers, the user must make his or her own BI PCD that represents the most challenging package configuration in the load. The BIPCD should also contain one or more CIs and items normally present during routine sterilization. Forexample, if routine loads contain instruments in peel pouches, then the appropriate BI PCD is a BI and a CI along with a representative instrument in a peel pouch. However, if wrapped sets are also routinelyprocessed, then a “dummy” wrapped set that contains a BI and one or more CIs and representativeinstruments should be used as the BI PCD. This is because wrapped sets provide a greater challengeto steam penetration and air removal than peel pouches.4. Which 3M™ Attest™ Biological Indicator should be used to monitor a table-top steam sterilizer?When determining which 3M Attest Biological Indicator to use to monitor a table-top steam sterilizer, it isimportant to first identify the method of air removal and the cycle temperature. Most table-top steamsterilizers are gravity-displacement units that generate steam from water that the operator pours into areservoir. Prevacuum table-top steam sterilizers that are connected to a boiler system are not as common.Once you know the table-top sterilizer’s method of air-removal and the temperature of the cycles used, you can refer to the table below to identify which 3M Attest Biological Indicator products meet your needs.*3M™ Attest™ 1262 is universal for all table-top steam sterilization cycles** Must be used in conjunction with 3M™ Attest™ 290 Auto-reader5. How often do I need to incubate a positive control biological indicator?AAMI ST79 recommends that a positive control BI be incubated every day a test BI is run. If several testBIs from the same lot are run on the same day, only one control BI from that lot needs to be incubated.Incubating a positive control BI for a visual color-change result ensures that:• the temperature of the incubator or Auto-reader is correct; • the viability of the spores has not been altered due to improper storage temperature, humidity,or proximity to chemicals; and• the culture media is capable of supporting growth. The lot number of the control must match the lot number of the test BIs. If a new lot of BIs is opened during the day, a new positive control should be incubated. Keep in mind that if you use two types of BIs to monitor your table-top steam sterilizer, you need to incubate a positive control for each BI type usedthat day. A positive control is a BI that is not sterilized; therefore, the spores should all be viable. When the control yields a positive result, this ensures that the processed or sterilized BI results are valid. This is important because you want to be sure that you are able to detect spores that survive the sterilization process. Running a positive control BI is good science – it is the quality assurance step that ensures the test BI results throughout the day are accurate.Air-removal methodCycle T emp. ºF 3M™ Attest™ BI Type BI incubation time Gravity270 only 3M™ Attest™ 1261 Biological Indicator 24 hours Gravity andPrevacuum250 and 2703M™ Attest™ 1262* Biological Indicator 48 hours Gravity270 only 3M™ Attest™ 1291** Rapid Readout Biological Indicator 1 hour Gravity2503M™ Attest™ 1292** Rapid Readout Biological Indicator 3 hours Prevacuum 270 3M™ Attest™ 1292** Rapid ReadoutBiological Indicator 3 hours6. Are Bowie-Dick test packs used to monitor table-top steam sterilizers?Bowie-Dick tests are a type of chemical indicator used in dynamic-air-removal (i.e., prevacuum) steam sterilizers for Equipment Control. The Bowie-Dick test monitors the efficacy of the vacuum system atremoving residual air from the sterilizer chamber and it also detects air reentrainment. Inadequate airremoval interferes with adequate sterilization. The Bowie-Dick test can detect inadequate air removalcaused by inadequate vacuum, inadequate steam penetration, air leaks, and non-condensable gases in the steam. The Bowie-Dick test is conducted in an empty chamber and the recommended frequency for routine sterilizer efficacy monitoring is daily before the first processed load. If a table-top steam sterilizer is connected to the boiler system and has prevaccum capability, it should be tested daily with a Bowie-Dick test pack. If you are uncertain whether or not to run a Bowie-Dick test in your sterilizer, check with the sterilizer manufacturer.7. When and how should qualification testing be done for table-top steam sterilizers?As with other types of steam sterilizers used in a health care setting, qualification testing of table-topsterilizers should be conducted after sterilizer installation, relocation, major repairs, and malfunctions,and after sterilization process failures. For qualification testing of a table-top sterilizer, a representative BI PCD should be run in three consecutive full loads and the load items should be quarantined until the BI results are negative. If a table-top steam sterilizer is connected to the boiler system and has prevaccum capability, qualification testing would also include three consecutive cycles with a Bowie-Dick test pack.Remember to document when and why qualification testing was conducted as well as the results of the BIs, CIs, and physical monitors used during the qualification testing.8. What information should be documented for each steam sterilization cycle?Each package must be traceable to the load in which it was sterilized. This is usually accomplished by labeling each package in each load with a lot control number including the sterilization date, the sterilizer number, and the load number. If the sterility of a load is later called into question, it is important that all of the packages from that load can be identified and pulled from use or recalled.AAMI ST79 recommends that the following information should be recorded and maintained for eachsterilization cycle:a) the lot number;b) the specific contents of the lot or load, including quantity, department, and a specificdescription of the items (e.g., towels, type/name of instrument sets);c) the exposure time and temperature, if not provided on the sterilizer recording chart;d) the name or initials of the operator;e) the results of biological testing, if applicable;f) the results of Bowie-Dick testing, if applicable;g) the response of the CI placed in the PCD (BI challenge test pack, BI challenge test tray,or CI challenge test pack), if applicable; andh) any reports of inconclusive or nonresponsive CIs found later in the load.1The physical monitors (e.g., digital printout) for each cycle should be dated and signed by the operator and saved in the sterilizer records. Additionally, a log of repairs and preventive maintenance should be maintained for each sterilizer. Sterilizer and load information may be maintained in a paper or electronic record keeping system.Summary:T able-top sterilizers play a key role in medical device sterilization in office-based medical and dental clinics. Monitoring of table-top sterilizers in an office-based health care setting deserves the same attention to detail applied in hospital and surgical center sterile processing departments. A comprehensive quality control program for table-top steam sterilizers includes routine sterilizer efficacy testing (using physical monitors, CIs, and BIs), qualification testing, and proper documentation.Please recycle.

15、可以分离菌落作进一步鉴定，即掀起上层膜，由培养胶上判读卡Aerobic bacteria count=152测试片中含有一种红色指示染剂可使菌落着色,计算所有红色菌落(不论其大小和颜色深浅均计算之).Count=0在petrifilm AC测试片上,很容易解释,图2测试片上没有任何菌落生长.Count=16图3示有不多的菌落.Count=143Petrifilm AC测试片菌落数适宜计数范围是25-250,见图4Count=560测试片面积约为20cm2,当菌落数超过250个,如图5所示,为了估计菌落数,可选择其中一个或数个有代表性菌落的小方格(1cm2),计算平均菌落数,再乘以20可得到整个测试片上的菌落数.Count=tntc(estimated count=103)图6所示petrifilm AC测试片上菌落太多而无法计数(tntc)count=tntc(Estimated count=105)有很多高数量菌落,使整个生长区变粉色,如图7所示,你仅可在生长区边缘现观察到单个菌落,应计录为菌落太多无法计数(TNTC)count=tntc(Estimated count=103)有时菌落分布出现不均衡,如图8所示,这也记录为TNTC.Count=tntc(Estimated count=107)在图9中petrifilm AC测试片上的菌落,最先粗略一看是可计数的,然而,你密切注意到生长区边缘,能看到高密度的菌落,应记录为TNTC Estimated count=160很少数菌种会液化petrifilm AC测试片上的培养基,如图10所示.若有这种现象发生,可选择没有液化区的几个有代表性菌落的小方格(1cm2),计算平均菌落数.不要计数液化区内的红点.Count=83因为在petrifilm AC测试片上菌落是红色的,你会和不透明的不规则形状的事物颗粒区分开,见圆圈1和2.霉菌和酵母菌检验测试片Petrifilm and Mold count Mold TM测试片为预先制备好的培养基系统,它含有一种冷水可溶性的凝胶剂，营养基和一种指示染剂，可提供对比，利于菌落计数。
