WebWater flow is measured through a hydrophobic filter and correlated to microbial retention. Bacterial retention testing is the most sensitive integrity test for sterilization ability and microbial reduction, but this testing is destructive and therefore cannot be used if the filter needs to be put into service after testing as the filter would be contaminated with the test … WebFiltration removes particles and impurities from liquids and offers comprehensive solutions when different filtration volumes need to be filtered. Employing these solutions, typical …
WebHydrophobic membrane filters are typically used with compatible non-aqueous fluids. They are also commonly used as air, gas, or vent filters. Hydrophobic membrane filters are sometimes used with water or aqueous solutions; and, in these applications, they must first be prewet with a low surface tension, water miscible fluid prior to use. WebHydrophobic membranes are recommended for gas filtration, low surface tension solvents, and venting, and can be wet in organic solvents such as methanol, allowing both aqueous liquids and organic solvents to pass through.
