Vent Filters with Teflon (PTFE) Membrane

Sterile and non-sterile vent filters with a PTFE membrane and different connectors for use with venting applications. As with our other Teflon™ filters, these vent filters can withstand the most aggressive sample solutions.

Vent filters function like standard syringe filters, but the built-in connection options make it easier to hook them up as part of a venting separation process.

PTFE Vent Filter Options:

Sterile or non-sterile
Connections: 6 to 12 mm hose barb or 1/8 NPT
0.2 or 0.45 Micron pore size
65 mm Diameter
