It has been thoroughly tested and inspected before leaving the factory and when used in accordance with the procedures outlined in this manual, will provide you with many years of safe and dependable service.Rev. April 2004IMPORTANT SAFEGUARDSREAD BEFORE INSTALLING ORUSING THE EQUIPMENTYour Ultrasonic Processor has been designed with safety in mind. However, no design can completely protect against improper usage, which may result in bodily injury and/or property damage. For your protection and equipment safeguard, observe the following warnings at all times, read the operating instructions carefully before operating the equipment, and retain this instruction manual for future reference. If the ultrasonic Processor is used in a manner contrary to that specified in this instruction manual, the protection features designed into the unit may be impaired.• When mounting the probe, always clamp the converter housing. Never clamp the probe.• Make sure the Ultrasonic Processor is properly grounded via a 3-prong outlet.• High voltage is present in the power supply. Do not remove the cover. Refer all servicing to qualified service personnel.• To avoid electric shock, disconnect the electrical power cord before removing the cover prior to servicing.• Never operate the power supply unless it is connected to the converter.• Never secure anything to the probe, except at the nodal point (point of no activity).• Never touch a vibrating probe.• Never allow a microtip to vibrate in air for more than 10 seconds.• Never operate a threaded probe without a replaceable tip.• Air-cool the converter when sample temperature exceeds 100° C, and when working at high intensity for more than 30 minutes.• It is recommended that a sound abating enclosure or ear protection be used when operating the Ultrasonic Processor.CAUTIONLOW SURFACE TENSION LIQUIDS – ORGANIC SOLVENTS The probes (solid or with a replaceable tip) are tuned elements that resonate at a specific frequency. When using a ½” (13 mm) probe with a replaceable tip, if the replaceable tip is removed or isolated from the rest of the probe, the probe will no longer resonate at that frequency, and the power supply will fail.Unlike aqueous (water based) solutions, which rarely cause problems, samples containing solvents or low surface tension liquids are problematic. These liquids penetrate the probe/replaceable tip interface, and force the particulates into the threaded section isolating the tip from the probe.When processing samples containing solvents or low surface tension liquids ALWAYS use a solid probeSECTION 1 – INSTALLATIONINSPECTIONPrior to installing the Ultrasonic Processor, perform a visual inspection to detect any evidence of damage, which might have occurred during shipment. Before disposing of any packaging material, check it carefully for small items.The Ultrasonic Processor was carefully packed and thoroughly inspected before leaving our factory. The carrier, upon acceptance of the shipment, assumed responsibility for its safe delivery. Claims for loss or damage sustained in transit must be submitted to the carrier.If damage has occurred, contact your carrier within 48 hours of the delivery date. DO NOT OPERATE DAMAGED EQUIPMENT. Retain all packing materials for future shipment.ELECTRICAL REQUIREMENTSThe Ultrasonic Processor requires a fused, single phrase 3-terminal grounding type electrical outlet capable of supplying 50/60 Hz at 100 volts, 115 volts, 220 volts, or 240 volts, depending on the voltage option selected. For power requirements, check the label on the back of the unit.Should it become necessary to convert the unit for different voltage operation, proceed as follows.1. Ensure that the power cord is not connected to the electrical outlet.2. Open the fuse holder cover using a small screwdriver.3. Pull out the red fuse holder from its housing.4. To convert from 100/115V to 220/240V replace the two 3 Amp slow blow fuses,with 1.6 Amp fuses.5. To convert from 220/240V to 100/115V reverse the procedure above.6. Rotate the fuse holder 180º from its original position, and reinsert it into itshousing. For 100/115V operation the voltage displayed should be 115. For220/240V operation the voltage display should be 220.7. Change the electrical power cord as required.The Ultrasonic Processor should be installed in an area that is free from excessive dust,dirt, explosive and corrosive fumes, and extremes of temperature and humidity.SECTION II – OPERATIONPRINCIPLES OF ULTRASONIC DISRUPTIONThe ultrasonic power supply converts 50/60 Hz line voltage to high frequency electrical energy. This high frequency electrical energy is transmitted to the piezoelectric transducer within the converter, where it is changed to mechanical vibrations. The vibrations from the converter are intensified by the probe, creating pressure waves in the liquid. This action forms millions of microscopic bubbles (cavities), which expand during the negative pressure excursion, and implode violently during the positive excursion. As the bubbles implode, they cause millions of shock waves and eddies to radiate outwardly from the site of collapse, as well as generate extremes in pressures and temperatures at the implosion sites. Although this phenomenon, known as cavitation, lasts but a few microseconds, and the amount of energy released by each individual bubble is minimal, the cumulative amount of energy generated is extremely high. The larger the probe tip, the larger the volume that can be processed but at a lesser intensity. For information regarding the processing capability of each probe, consult the tables below.FUNCTIONS OF KEYS, CONTROLS, INDICATORS, AND CONNECTORS (cont.)REAR PANEL9 pin D-sub connector Connects to external actuation device, and enable power and frequency monitoring.Footswitch jack Connects to the footswitch cable.Coax connector Connects to the converter.Power module Connects to the electrical line cord and encases the fuse(s).9-PIN D-SUB CONNECTORPin No. Description1 Notconnected2 Notconnected3 Notconnected4 Enables connection to a frequency counter.5 Enables connection to an external power monitor (5 mv = 1 watt)6 Ground7 Energizestheultrasonicswhen connected to ground.8 and 9 Enables the intensity to be remotely adjusted using an external 10k potentiometer. See belowPREPARATION FOR USE1. Plug the electrical line cord into the electrical outlet, if the unit is already on; depress2. If the optional footswitch is used, insert the plug into the jack located on the rearpanel. Make sure that the plug is inserted forcefully all the way in.3. If the converter / probe assembly is not already assembled; screw the probe into theconverter and secure with wrenches provided.4. Mount the converter / probe assembly in a laboratory stand, secure the clamp to theupper section of the converter housing only. Do not secure the clamp to the probe.5. Connect the converter cable to the power supply.USING THE ULTRASONIC PROCESSORand the following control parameters.AMPLITUDE: The amplitude is the only parameter that must be set in order for the Ultrasonic Processor to be operational. The other control parameters – Timeand Pulse, do not have to be set for continuous operation. AMPL. displays theamplitude selected e.g. 40%. To set the amplitude when the ultrasonics is off,press the AMPL key and the numeric keys for a 40% reading on the screen –Ampl 40%, and the ENTER/REVIEW key.The screen will display:The Ultrasonic Processor is now ready for continuous operation. To energize the ultrasonics, press the START key or the footswitch. To de-energize the ultrasonics, press the key or release the footswitch. If the Time or Pulse functions must be used, refer to the appropriate paragraph(s) below.To increase or decrease the amplitude in small increments when the ultrasonics is on, depress the AMPL key to display Amplitude Setting on the screen, then depress the ▲or ▼key, as required.Immerse the microtip half way into the sample. If the probe is immersed to an insufficient depth, air will be injected into the sample, causing the sample to foam.Since the amplitude required is application dependent and subject to the volume and composition of the sample, it is recommended that the amplitude be selected empirically, by increasing or decreasing the level of intensity as required as the sample is being processed.TIMER:In the pulsed mode the processing time will be different from theelapsed time because the processing time function monitors and controls only the ON portion of the duty cycle. For example, for 1 hour processing time, theelapsed time will be 2 hours if the ON and OFF cycle are set for 1 second. To set the processing time, press the TIMER key.The screen will display:Using the numeric keys, set the processing time as required:Press the ENTER/REVIEW key. The screen will display:PULSER:By inhibiting heat build-up in the sample, the pulse function enablessafe treatment of temperature sensitive samples at high intensity. In addition,pulsing enhances processing by allowing the material to settle back under theprobe after each burst. The ON and OFF pulse duration can be set independently from 01 second to 59 seconds. During the OFF portion of the cycle, the redindicator on the key will illuminate. If the OFF portion of the cycleexceeds three seconds, a cautionary message - Sonics in OFF Cycle - will warnthe operator against touching the ultrasonic probe. To set the pulser, press PULSE key.The screen will display:Using the numeric keys, set the ON portion of the cycle, and press the ENTER/REVIEW key.The screen will display:Using the numeric keys set the OFF portion of the cycle.The screen will display:Press the ENTER/REVIEW key.The screen will display:REVIEW: The REVIEW function provides a “window” on the process by displaying various operating parameters without process interruption. Pressing theENTER/REVIEW key repeatedly during processing will consecutively display the following information.a) Selected amplitude:e.g. Amplitude 40%b) Selected processing time and elapsed processing time:e.g. Set 0:30:00 Time 0:22:10c) Selected pulsing cycle, and actual pulsing cycle:e.g. Pulse 01 01 / 01 00d) Amount of power in watts, and accumulated amount of energy in JOULESdelivered to the probe:e.g. 20 watts 0000000 Joulese) Elapsed time since processing was initiated:e.g. Elapsed time 0:44:20SECTION III – SERVICE INFORMATIONYour Ultrasonic Processor was designed to provide you with years of safe anddependable service. Nevertheless, because of component failure or improper usage, the possibility does exist that it might not perform as it should, shut down due to an overload condition or that it will stop working all together. The most probable causes formalfunction are listed below and should be investigated.The unit was plugged into an electrical outlet that provides a different voltage fromthat required.

Care should be exercised to provide adequate packing to insureagainst possible damage in shipment. The Ultrasonic Processor should be sent to the “Service Department” with all transportation charges prepaid and return of shipment indicated.Please obtain a Return Authorization Number prior to returning the instrument.SECTION IV - OPERATING SUGGESTIONS AND TECHNIQUES DISRUPTING CELLSThe disruption of cells is an important stage in the isolation and preparation of intracellular products. From research levels through to production, many areas of biotechnology, particularly recombinant technology, necessitate the use of ultrasonics for cell disruption. Although some biological products are secreted from the cell or released during autolysis, many others require sonication to release intracellular material. Cell disruption focuses on obtaining the desired product from within the cell, and it is the cell wall that must be disrupted to allow cell contents extraction.Single-cell organisms (micro-organisms) consist of a semipermeable, tough, rigid outer cell wall surrounding the protoplasmic membrane and cytoplasm. The cytoplasm is made up of nucleic acid, protein, carbohydrates, lipids, enzymes, inorganic ions, vitamins, pigments, inclusion bodies, and about 80% water. In order to isolate and extract any of these substances from inside the cell, it is necessary to break the cell wall and protoplasmic membrane. In some cases the cell may excrete the desired substance without assistance, but in most cases, the cells must be lysed and sonicated in order for these substances to be released. Breaking cell membranes and releasing the contents present significant challenges. The process must be fast and thorough to maximize the protein yield. Because the energy applied must be great enough to break the cell membranes or walls, yet gentle enough to avoid physically or chemically damaging cell contents, the Vibra-Cell with its variable intensity capability is ideally suited for this application.The level of intensity that should be used is application dependent. For example high intensity might be recommended for the break up of cells, but should never be used when the release of intracellular components might be objectionable e.g. Organelle isolation. The ability to control the amplitude at the probe tip is a prerequisite for process optimization. And because each application requires its own set of processing parameters, due to variation in volume and composition, the optimum amplitude can only be determined empirically. When processing a new sample, it is recommended that the amplitude be set first at 50% (30% with a microtip) and then increased of decreased as required.Yeast, gram-positive bacteria, and to a lesser extent, gram-negative bacteria have considerably harder cell walls in comparison to animal cells, and require relatively high power for cell disruption.Gram negative bacteria typically require 10 to 15 minutes of processing, while staphylococcus requires 20 to 30 minutes.Microorganisms differ greatly in their sensitivity to ultrasonic disintegration. For example, the most readily disintegrated are the rod-like forms (bacilli), while the spherical organisms (cocci) are much more resistant. The group Mycobacteria, to which the tuberculosis organism belongs, is particularly difficult to disrupt. Generally, animal cells are more easily disintegrated that plant cells, and red blood cells are more readily disintegrated than muscle cells because they lack a protective cell wall.Cellular disruption is the first step in RNA isolation and one of the most critical steps affecting yield and quality of the isolated RNA. Typically, cell disruption needs to be fast and thorough. Slow disruption, for example placing cells or tissue in guanidinium isothiocyanate (GITC) lysis solution for a long time prior to sonication, may result in RNA degradation by endogenous RNases released internally. This is especially a concern when working with tissues high in endogenous RNase such as spleen and pancreas. Disrupting frozen tissue is more time consuming and cumbersome that processing fresh tissue, but freezing samples is sometimes necessary. Samples are usually frozen when, 1) they are collected over a period of time and thus, cannot be processed simultaneously; 2) there are many samples, 3) samples are collected in the field, or 4) mechanical processing of fresh samples is insufficient for thorough disruption. A mortar and pestle or bag and hammer are typically used when the starting material is frozen. RNA will remain intact in tissues for a day at 37ºC, a week at 25ºC a month at 4ºC and indefinitely at subzero temperatures.Ultrasonic processing will typically cause the temperature of the sample to increase especially with small volumes. Since high temperatures inhibit cavitation, the sample temperature should be kept as low as possible - preferably just above its freezing point. This can be accomplished by immersing the sample vessel in an ice-salt-water bath. Temperature elevation can also be minimized by using the pulser.Increasing hydrostatic pressure (typically 15-60 psi) and viscosity can enhance cell disruption. For microorganisms, the addition of glass beads in the 0.5 to 1mm size range promotes cell disruption. Beads are almost a prerequisite when working with spores and yeast. A good ratio is one volume of beads to two volumes of liquid. Glass beads are available from Cataphote, Inc. P.O.

Lysozyme, byaluronidase, glycosidase, glucalase, lyticase, zymolase and lysostaphin digestion are among the enzymatic methods frequently used with yeast and Lysozyme with bacteria. Enzymatic treatment is usually followed by sonication in a GITC lysis buffer. Collogenase may be used with collogen, lysostaphin with staphylococcus, and trypsin hyaluronidase with liver and kidney.If enzymes cannot be used, the following procedures should be considered: Freezing the sample at -70°C overnight, then thawing it in water immediately prior to ultrasonic processing.Most animal tissues can be processed fresh (unfrozen). It is important to keep fresh tissue cold and to process it quickly (within 30 minutes) after dissection. When working with fresh tissue, the cells must be sonicated immediately at the time the GITC lysis solution is added. This can be done by dispensing the lysing solution in the tube, adding the tissue and immediately sonicating. Samples should never be left sitting in lysis solution, undisrupted. Large samples of hard tissues should be first treated in a blender or a mechanical homogenizer.Animal tissues that have been frozen after collection should be disrupted by grinding in liquid nitrogen with a mortar and pestle. During this process, it is important that the equipment and tissue remain at cryogenic temperatures. The tissue should be dry and powdery after grinding. Grinding should be followed by thorough sonication in a GITC lysis buffer. Processing frozen tissue in this way is cumbersome and time consuming, but effective.Cultured cells are normally easy to disrupt. Cells grown in suspension are collected by centrifugation, rinsed with PBS to remove culture medium, and then lysed by sonicating in a GITC lysis buffer. Placement of the vessel on ice while washing and lysing the cells will further protect the RNA from endogenous RNases released during the disruption process.Soft, fresh plant tissue can often be disrupted by sonicating in a lysis buffer. Other plant tissues, like pine needles, need to be ground dry, without liquid nitrogen. Some hard, woody plant materials require freezing and grinding in liquid nitrogen prior to being ultrasonically processed. Plant cell suspension cultures and calluses can typically be sonicated in a lysis buffer within 2 minutes. The diversity of plants and plant tissue make it impossible to give a single recommendation for all. However, most plant tissues typically contain polysaccharides and polyphenols that can coprecipitate with RNA and inhibit downstream assays. Treating a plant tissue lysate with polyvinylpyrrolidone (PVP) will precipitate such problematic components from the lysate before the actual RNA isolation is carried out.Whenever possible, the tissues should be diced very small to permit movement within the liquid. Tough tissues such as skin and muscle should be macerated first in a blender or the like for about 10 seconds, and confined to a small vessel during ultrasonic treatment. If sub-cellular particles are desired intact, the amplitude should be kept low, and the processing time increased.Yeast can be extremely difficult to disrupt because their cell walls may form capsules or nearly indestructible spores. To process yeast, sonicate in a tube containing the sample, guanidinium-based lysis buffer and small glass beads (0.5 – 1 mm). Pretreatment withzymolase, glucalase and / or lyticase to produce spheroplasts that are readily lysed may also be useful.To disrupt filamentous fungi, scrape the mycelial mat into a cold mortar, add liquid nitrogen and grind to a fine powder with a pestle. The powder can then be thoroughly sonicated in lysis buffer to solubilize completely. As fungi may also be rich in polysaccharides, pretreatment with polyvinylpyrrolidone (PVP) may be beneficial. Bacteria, like plants, are extremely diverse; therefore, it is difficult to make one recommendation for all bacteria. Ultrasonic processing will lyse most Gram positive and Gram negative bacteria, including mycobacteria. Although it is recommended that glass beads and lysis solution be used; it is possible to lyse some Gram negative bacteria by sonicating in lysis solution without beads. Bacteria cell walls can be digested with lysozyme to form spheroplasts. Gram positive bacteria usually require more rigorous digestion and longer processing time. The spheroplasts are then lysed with sonication in GITC lysis buffer.Disruption of cells found in soil and sediments is accomplished one of two ways. One technique isolates the bacterial cells from the material prior to the RNA isolation procedure. This is accomplished by homogenization of wet soil in a mechanical blender followed by a slow speed centrifugation to remove fungal biomass and soil debris. The supernatant is centrifuged again at a higher speed to pellet the bacteria cells. Cells can then be lysed as described above for bacteria. Other techniques describe RNA isolation from the soil or sediment directly. For example, one method requires soil to be added to a diatomaceous earth and lysis buffer, and then sonicated. The sample is then centrifuged to remove solid debris.Always immerse the probe deep enough below the surface of the sample to inhibit aerosoling or foaming, foaming substantially reduces cavitation. Processing at a lower power setting without foam is much more effective than processing at a higher power setting with foam. Decreasing the power, increasing processing time and lowering the temperature of the sample will usually prevent aerosoling and foaming. Do not use any antifoaming agents or surfactants.During cavitation, free radicals are formed which, if they are allowed to accumulate, can greatly affect the biological integrity of the sample by reacting with proteins, polysaccharides, or nucleic acids. Although during short periods of processing their formation is not normally considered a problem; for longer durations, the addition of free radical scavengers such as, carbon dioxide, N2O, cysteine, reduced glutahione, dithiothreitol or other SH compounds, might be beneficial. Saturating the sample with a protective atmosphere of helium or nitrogen gas, or dropping a small pellet of dry ice in the sample, will also inhibit free radical formation. Whereas it is true that gas is required for effective cellular disruption, it is not necessary that the vapor phase be oxygen or air since any gas except carbon dioxide will work just as well.21Various methods can be used to measure the efficiency of the disruption. For example, a visual count can be made using a microscope.For greater accuracy, a protein assay could be used. This procedure is widely recognized as a good method for measuring cell disruption by taking into account the amount of protein released after disruption. The disrupted cells are then tested and checked against this number for percentage breakage.There are several types of protein assays. One commonly used is the Folin Reaction (Lowry Assay) method, as it is comparatively simple and provides consistent results. This colorimetric method has a sensitivity to protein of around 8 µg / mL in the assay solution.The assay turns blue in the presence of proteins due to the reaction of copper ions in the alkaline solution with protein and the reduction of phosphomolybdate- phosphotungstic acid in the Folin reagent by aromatic amino acids in the treated protein.Fractional protein release, Rp, is calculated using the following equation and multiplying the result by 100:Rp = Cf – CbCt – CbCf = Free proteinCt = total proteinCb = Background proteinThis gives the actual disruption percentage, taking into account the background levels of protein before disruption.Since the greatest concentration of energy is beneath the probe, it is imperative that the sample be kept as close to the tip as possible, liquids are easily processed because the free moving cells circulate repeatedly below the probe. Solid materials however have a tendency to be repelled by the ultrasonic, and should be processed in a vessel large enough to accommodate the probe, yet small enough to restrict sample movement. For small samples, conical shaped test tubes are recommended.Allowing the probe to contact the vessel will decrease the power output, and cause minute grey glass particles to migrate into the sample. Although these glass particles will not adversely affect the chemical composition of the sample, they will form a thin grey layer on centrifuging. If the probe has to come in contact with a solid sample, use a standard 20mm (3/4”) diameter stainless steel centrifuge tube cut to 70mm (3”) length. Do not use a glass tube. Microtips must never allowed to come in contact with anything but the liquid, because the stress resulting at the point of contact with a hard surface will cause the microtip to fracture. Although larger probes will not fracture if they come in contact with a glass vessel, they may cause the vessel to fracture.Before each application, place the tip in water or alcohol and energize the power supply for a few seconds to remove any residual substances. If concerned about contamination from previous use, clean the probe with a 20% Virkon solution and rinse with distilled water. Because Virkon®, Dupont's broad spectrum cleaner / disinfectant is effective against a wide range of virus, bacteria and fungi, it is ideally suited for that purpose.
