Pall 4402 Vent Filter Vacushield 0.2 um Pore 50 mm Disc with Hose Barb - 3 Filters

The Pall 4402 Vacushield Vent Filter is a pack of three filters designed to protect vacuum pumps and systems from liquid and aerosol contamination.

These filters utilize a hydrophobic PTFE (polytetrafluoroethylene) membrane with a 0.2 µm pore size. This pore size effectively traps bacteria, microorganisms, and other particulate matter, preventing them from entering the vacuum system and causing damage or contamination. The hydrophobic nature of the PTFE membrane prevents aqueous liquids from passing through, further safeguarding the vacuum pump. These vent filters are crucial for maintaining aseptic conditions in various laboratory applications, such as cell culture, microbiology, and sterile filtration processes, while also protecting laboratory personnel from potential biohazards.
