Jul 28, 2015 · When we perform sterility testing we use 0.45 micron filter but when we prepare and filter the disinfectant solution we use 0.22 micron filter. During batch preparation of SVP, LVP and liquid injections we also use 0.22 micron pore size filter for filtration of batch. The reason behind these questions is the purpose of using these filters.
LabFriend is open, but please expect delays. The COVID-19 crisis continues to cause heavy fluctuations in prices, stock levels, ETAs and freight estimates for manufacturers and suppliers alike.
Syringe filters. Available with either PP, PTFE or nylon membrane. Membranes are available in either 0,2 or 0,45 µm pore size, with the choice often made on analytical column packing size. If the column packing size is larger than 3 μm then use 0,45 μm, and if 3 μm or smaller then use 0,2 μm. PP membrane: These polyvalent filters are

Microbiological filters from a variety of reputable manufacturers are available through Hach, including Pall, Millipore, Xenomax, and Gelman. Commonly used in detection and enumeration of coliform organisms, 0.45 µm, 47 mm diameter filters are available in various quantities, along with 25 mm sizes and different pore diameters.
Sample filtration using syringe filters containing 0.45 μm (HPLC) or 0.2 μm (UHPLC) pore size membranes will also extend the life of chromatography columns by preventing particulate from blocking the flow path between the column packing. PVDF syringe filters offer excellent chemical compatibility, including aggressive acids and alcohols.

Syringe filters with different pore size ratings are suitable for different applications. For example, syringe filters containing 0.45 μm are typically used for HPLC sample preparation and 0.2 μm is used for UHPLC. In life science applications 0.1 and 0.2 µm pore sizes provide sterilization of buffers, culture media, and additives.
