费休氏容量法测量冻干人用狂犬病疫苗中水分含量的不确定度分析

费休氏容量法测量冻干人用狂犬病疫苗中水分含量的不确定度分析邱文娜饶玲王永智方朝东李磊江苏省泰州医药高新技术产业园区疫苗工程中心，江苏泰州 225300[摘要] 目的对费休氏容量法测量冻干人用狂犬病疫苗中水分含量的不确定度进行分析，为评价该方法的准确性和可靠性提供科学依据。

方法建立费休氏容量法测量冻干人用狂犬病疫苗中水分含量的数学模型，找出影响不确定度的因素，并对各个不确定度分量进行评估。

结果计算出各变量的不确定度，取包含因子K=2，置信概率为95%，费休氏容量法测量冻干人用狂犬病疫苗中水分含量的扩展不确定度为0.082%。

结论卡尔费休容量法检测冻干人用狂犬疫苗中水分含量时，不确定度主要由测定时卡尔费休试液的消耗体积和滴定度F值产生，该评价方法适用于冻干狂犬疫苗水分测定的不确定度评定与报告。

Methods A mathematical model for measuring moisture content in freeze-dried rabies vaccine for human use was established by Karl fischer method,and the factors affecting the uncertainty were found and the components of the uncertainty were evaluated. Results The uncertainty of each variable was calculated and the inclusion factor K=2 was taked.The confidence probability was 95%.The expanded uncertainty of Karl fischer method for measuring moisture content in freeze-dried rabies vaccine for human use was 0.082%. Conclusion When Karl fischer method is used to detect the moisture content in freeze-dried rabies vaccine for human use,the uncertainty is mainly generated by the consumption volume and titer F value of Karl fischer test solution at the time of determination.This evaluation method is applicable to the evaluation and report of the uncertainty in the determination of moisture content in freeze-dried rabies vaccine.[Key words] Karl fischer method;Freeze-dried rabies vaccine for human use;Moisture content;Uncertainty assessment狂犬病是由狂犬病毒所致的人畜共患急性传染病，流行性广，病死率100%，有效预防该病的措施是接种狂犬病疫苗[1]。

鱼虾加工副产物生成甲壳素的工业流程1.首先，生产车间将收集来自鱼虾加工的副产物。

First, the production workshop will collect the by-products from fish and shrimp processing.2.副产物包括鱼骨、虾壳等。

The by-products include fish bones, shrimp shells, etc.3.这些副产物经过清洗和加工后，被送入萃取设备。

After cleaning and processing, these by-products are sent to the extraction equipment.4.萃取设备会用酸或碱对副产物进行处理。

The extraction equipment will treat the by-products with acid or alkali.5.处理后的副产物会生成液体和固体两部分。

The treated by-products will generate liquid and solid parts.6.固体部分主要是富含甲壳素的残渣。

The solid part mainly consists of residues rich in chitosan.7.过滤和离心技术被用来分离液体和固体。

Filtration and centrifugation techniques are used to separate the liquid and solid.8.液体部分则包含溶解的盐和碱液。

The liquid part contains dissolved salts and alkali solution.9.固体部分被送入脱水设备进行浓缩和干燥。

The solid part is sent to dewatering equipment for concentration and drying.10.干燥后的甲壳素残渣可作为饲料原料。

thermo fisher scientific冻存管规格 -回复

thermo fisher scientific冻存管规格-回复Thermo Fisher Scientific is a leading provider of scientific research equipment and solutions. One of their key products is the cryogenic storage tube, commonly known as the freezer tube or cryotube. In this article, we will explore in detail the specifications of Thermo Fisher Scientific's cryogenic storage tubes.Thermo Fisher Scientific offers a wide range of cryogenic storage tubes, catering to diverse research needs. These tubes are designed to store biological samples at extremely low temperatures, typically at or below -80 degrees Celsius, ensuring the preservation of sample integrity. Let's delve into the key specifications of these tubes.1. Tube Material:Thermo Fisher Scientific cryogenic storage tubes are typically made of high-quality polypropylene (PP) material. PP possesses excellent chemical resistance, making it suitable for the storage of a wide range of biological samples, including proteins, nucleic acids, and cells. It also offers good thermal insulation properties, ensuringtemperature stability during storage.2. Tube Capacity:Thermo Fisher Scientific's cryogenic storage tubes are available in various capacities to accommodate diverse sample sizes. They typically range from 0.5 ml to 5 ml, allowing researchers to select the appropriate tube size based on their specific experimental requirements. The tubes are usually marked with visible graduations to enable accurate sample volume measurement.3. Tube Closure Systems:To ensure reliable sample containment and prevent any leakage, Thermo Fisher Scientific cryogenic storage tubes feature robust closure systems. These commonly include screw caps with anO-ring seal. The O-ring creates a secure and airtight seal, minimizing the risk of sample contamination or evaporation. Some tubes also come with external thread caps for increased sealing efficiency.4. External Markings:Thermo Fisher Scientific's cryogenic storage tubes are designed with external markings, facilitating quick and accurate sampleidentification. The tubes are often printed with alphanumeric grids or barcode labels on the side, allowing researchers to label and organize their samples efficiently. The markings are generally resistant to common laboratory chemicals, ensuring their durability during sample handling and storage.5. Tube Bottoms:Cryogenic storage tubes from Thermo Fisher Scientific come with various bottom configurations to meet specific research needs. These can include conical, round, or self-standing bases. Conical bottoms are suitable for efficient sample recovery, while round bottoms are commonly used for mixing and vortexing applications. Self-standing tubes have a flat base, enabling them to stand upright without the need for additional support racks.6. Tube Compatibility:Thermo Fisher Scientific's cryogenic storage tubes are designed to be compatible with various storage systems and accessories commonly used in laboratories. These tubes can be stored in liquid nitrogen or mechanical freezers without any adverse effects on sample quality. They are also compatible with automated sample handling systems, making them suitable for large-scale researchprojects.7. Tube Sterility:To ensure sample integrity and minimize the risk of contamination, Thermo Fisher Scientific cryogenic storage tubes are available in sterile and non-sterile options. Sterile tubes are subjected to sterilization methods such as gamma irradiation or ethylene oxide treatment. Non-sterile tubes, on the other hand, provide flexibility for researchers to carry out their own sterilization procedures if required.In conclusion, Thermo Fisher Scientific offers a comprehensive range of cryogenic storage tubes with various specifications. These tubes are designed to meet the critical storage needs of researchers, providing reliable sample containment and preservation at ultra-low temperatures. With their extensive range of capacities, closure systems, markings, and compatibility, Thermo Fisher Scientific cryogenic storage tubes are an essential tool in the scientific community for the successful preservation of valuable biological samples.。

葡聚糖能够提供胶体渗透压，帮助维持分离液的稳定性。

工作原理h i st op aq ue分离液的工作原理基于细胞的密度差异和分层离心技术。

当细胞悬液与hi st op a qu e分离液混合后，由于各个细胞种类的密度不同，它们会在分离液中形成不同层次。

这种密度梯度可由F ico l l-400和其他添加物调节。

具体的分离过程通常包括以下几个步骤：1.混合：将待分离的细胞悬液与hi st op a qu e分离液充分混合，使细胞均匀地分散在分离液中。

2.离心：将混合的样品进行离心分离。

离心过程中，细胞在分离液中根据密度不同而在不同层次聚集。

费舍尔试剂

费舍尔试剂费舍尔试剂是一种常用的化学试剂，用于检测蛋白质、氨基酸等物质的浓度。

它是一种有机化合物，具有特殊的颜色反应，能够与特定的化合物发生显色反应，从而实现浓度的定量测定。

费舍尔试剂的主要成分是二苯基甲酮（diphenylmethanone），它是一种无色结晶体，可溶于有机溶剂如乙醇、乙酸等。

二苯基甲酮是一种有机化合物，其分子结构中含有两个苯环和一个甲酮基团。

费舍尔试剂的显色反应基于二苯基甲酮与特定物质发生的酸碱反应。

在酸性条件下，二苯基甲酮会与目标物质发生酸碱反应，形成有色产物。

这种显色反应可用于测定蛋白质、氨基酸等物质的浓度。

费舍尔试剂常用于生物化学实验室中，用于测定蛋白质溶液的浓度。

在实验中，将待测蛋白质溶液与费舍尔试剂混合，观察混合液的颜色变化。

混合液的颜色越深，说明蛋白质的浓度越高。

费舍尔试剂的测定原理是基于费舍尔试剂与蛋白质分子中的酸性氨基酸残基发生反应，生成有色产物。

这种反应是一种选择性的反应，只有含有酸性氨基酸残基的蛋白质才能与费舍尔试剂发生反应，其他蛋白质或氨基酸则不会产生显色反应。

费舍尔试剂的应用范围很广，除了用于测定蛋白质的浓度外，还可以用于测定氨基酸、肽类物质的浓度。

此外，费舍尔试剂还可以用于检测其他含有酸性氨基酸残基的化合物，如某些药物、酸性糖类物质等。

费舍尔试剂的测定方法相对简单，操作方便。

只需将待测物质与费舍尔试剂混合，经过适当的反应时间后，观察混合液的颜色变化即可。

根据混合液的颜色深浅，可以进行定量测定，计算出目标物质的浓度。

费舍尔试剂不仅在实验室中有广泛的应用，也在生物工程、医药等领域发挥着重要的作用。

它的使用方便、灵敏度高、结果准确可靠，成为生物化学分析中不可或缺的试剂之一。

费舍尔试剂是一种常用的化学试剂，可以用于测定蛋白质、氨基酸等物质的浓度。

它基于二苯基甲酮与目标物质发生酸碱反应的显色特性，能够实现定量测定。

费舍尔试剂在实验室和生物工程领域都有广泛的应用，为科学研究和生产提供了重要的支持。
