sterile filter membraneThe filter is a type of filtration equipment widely used in biopharmaceuticals, food industry, hygiene and other fields. It is mainly used for biological Products and liquid pharmaceuticals are sterile filtered. The following is an introduction to some parameters of the film.
1. Material
Sterile Filter membraneCommonly used materials for filters include polyamide, polycarbonate, polyvinylidene fluoride, etc. Each material has its own scope of application and characteristics. For example, polyamide has high temperature resistance and chemical stability. , suitable for filtration under high temperature and high pressure conditions; polycarbonate material has good corrosion resistance and mechanical strength, and is suitable for filtration under acid and alkali environments.
2. Pore size
The pore size of the filter is usually between 0.1-10 microns. Different pore sizes are suitable for different filtration needs. For example, a pore size of 0.2 microns can filter most bacteria and microorganisms well and is the pore size of a common sterile membrane filter.
3. Filtration area
Filtration area refers tosterile filter membraneThe useful filtration area of the filter, usually measured in square meters. Filters of different specifications have different filtration areas. You can choose the appropriate specifications and area according to your needs.
4. Working pressure
Working pressure refers to the pressure that the filter can withstand, usually The unit is bar. Pay attention to selecting a working pressure that meets the requirements to ensure the normal operation of the filter and avoid problems such as leakage.
5. Cleaning methods
Cleaning methods are divided into two types: chemical cleaning and physical cleaning. It is necessary to choose the appropriate cleaning method according to the specific situation. Chemical cleaning usually uses cleaning agents to remove bacteria and microorganisms; physical cleaning uses physical forces such as water flow or air flow to clean, and is suitable for some relatively simple filters.
In summary, sterile filter membrane filter parameters include material, pore size, filter area, working pressure and cleaning method etc. Choosing appropriate parameters can ensure the normal operation of the filter and achieve the expected filtering effect.
