Laboratory Filter Holders – Sigma-Aldrich Filter housings are used in conjunction with cut disc membrane filters providing structural support and creating a seal around the membrane to prevent filtrate contamination. Reusable syringe filter holders are suited for filtering or clearing small amounts of liquid where a replaceable or removable filter is desired. Filtration Membrane Discs | Fisher Scientific Filter membrane can be made from cellulose, mixed cellulose esters (MCE), polyviny...

LifeASSURE PFS Series PTFE Filters The hydrophobic PTFE filter membrane prevents wetting with aqueous liquids or moisture that can block free air flow. Some applications, however, may require filtration of aggressive fluids such as acids or bases. Depending on compatibility, LifeASSURE PFS series PTFE filters can be used to provide sterile filtration of these fluids by prewetting Emflon® HTPFR Sterile Air Filter Cartridges – Pall Corporation These sterile air filters incorporate a doub...
