sterile membraneA filter is a device used for sterile filtration of liquids at low pressure. It usually consists of a filter element and a shell. The filter element contains this filter membrane, and the shell is responsible for introducing the liquid to be filtered into the filter element and discharging the filtered liquid. This kind of filter can be widely used in biopharmaceutical, food and beverage, microelectronics and other fields.
The interior of the filter element of the filter is usually made of multi-layer composite materials. The material of the central layer is made of polysulfone, polypropylene or Made of polymer materials such as polyester. Such materials can ensure biocompatibility and chemical inertness while ensuring filter membrane performance. In addition, the periphery of the filter element is supplemented by a support net and filter cloth to ensure the stability and pressure resistance of the filter element structure.
sterile filter membraneA major advantage of the filter is that it can well prevent microbial contamination such as bacteria and viruses. Its working principle is to filter microorganisms through the filter membrane in the filter element. This kind of filter membrane is usually made of polyamide, polycarbonate, polyester and other materials, and can effectively remove bacteria and viruses with a diameter of more than 0.1 micron. In addition, filters are able to retain useful biomolecules such as proteins, peptides and nucleic acids.
sterile filter membraneFilters are widely used, and their main application areas include:
1. Biopharmaceuticals: In the field of biopharmaceuticals, filters are widely used for sterile filtration of fermentation broth and cell culture fluid to prevent microbial contamination. At the same time, it can also be used for the extraction and purification of useful molecules such as proteins and antibodies.
2. Food and Beverage: sterile filter membrane Filters can be used for water treatment, juice clarification, and beer in the food and beverage industry The factory’s yeast filtration and other aspects ensure the sterility of the product while maintaining the original taste and color of the product.
3. Microelectronics: In microelectronics manufacturing, sterile membrane filters can be used to filter deionized water , to remove tiny particles and organic matter in the water to ensure the production quality of the chip.
In short, sterile membrane filters play a key role in the fields of biopharmaceuticals, food and beverages, and microelectronics. , can be said to be an indispensable device. Interested parties are welcome to enter the store and contact us.
