With the continuous development of society, a dazzling array of filter membranes have also filled the market. Among them, microporous sterilizing filter membrane is widely used because of its excellent performance. use and approval. Widely used in laboratory sterilization filtration.
The filtration sterilization method is to filter liquid or gas through a filter membrane with micropores to make it larger than the pore size of the filter membrane. Microbial particles such as microorganisms are retained, thereby achieving the method of sterilization. The filtration sterilization method is mostly used for reagents, enzyme solutions, serum, culture fluids, etc. that are prone to decomposition, denaturation and failure when exposed to heat. At present, microporous membrane metal filters or plastic filters are commonly used for positive pressure filtration sterilization, or glass fine bacterial filters and filter balls are used for negative pressure filtration sterilization. The pore size of the filter membrane should be in the range of 0.22-0.45 μm or a smaller bacterial filter membrane should be used. After the solution passes through the filter membrane, small bacteria and spores are blocked because they are larger than the pore size of the filter membrane, and the adsorption effect of the filter membrane is used to Prevent the penetration of bacteria smaller than the pore size of the filter membrane.
The currently independently developed microporous sterilizing filter membrane series can be used as a material for filtration and sterilization. The film is prepared using a special biaxial stretching technology. It is a filtration composite material compounded with other substrates. This material can intercept impurities such as small bacteria while having a large flux.
Microporous sterilizing filter membrane Used for gas filtration to achieve sterility, temperature resistance, strong acid and alkali resistance, and wide chemical applicability . It is widely used in water purifiers, food and beverages, medicine and health, electronics, chemical industry, environmental monitoring and other fields. It has various pore size specifications of 0.1μm, 0.22μm, 0.45μm and 1μm.Microporous sterilization filter membraneIt can effectively remove small bacteria, germs, toxins, heavy metals and other impurities in the water. PTFE membrane technology has always been the core of the business, playing an important role in biopharmaceuticals, equipment, food and beverages, semiconductor processes, communications and other fields. The pore-forming capacity ranges from 0.1μm to 1μm, providing fine filtration, hydrophobic breathability, and sound transmission. and other functional solutions.
