GF Prefilter Syringe Filter????FilterBio? GF Pre-filter?Syringe Filters are syringe-operated filters with glass fiber prefilter. It’s white color, for the housing and membrane, it’s welded together. Compared with the common syringe filter, it has better flow rate and better filtration efficiency. The Classic range is available in all of the major membranes including Nylon, PTFE, PVDF, and PES, which are supplied in 13mm, 25mm, 30mm formats in polypropylene housings.Features:Experience:?All White colorBetter Filtration Efficiency:?Glass fiber pre-filterApplication Compatibility:?Broad range of filtration media meets diverse application needs and best for chromatography applicationSterile:?Filters can be purchased pre-sterilized by Gamma radiation and individually packagedValidated HPLC PerformanceHPLC certification which guarantees the filters will not produce extraneous peaks in the UV range.?100% integrity tested with higher burst strength ratings assuring they will perform consistently.?Available in 13 and 25mm sizes and available in sterile, too.?0.45μm for most clarification applications and 0.22μm when fine particulate removal is required.
