Bacterial Air Vents without Closing Cap

Many medical devices require vents to keep their internal pressure in balance with the ambient pressure.

This avoids the deformation of rigid plastic containers and interruptions in flow of fluids.

Our product must protect the fluid path from bacterial contamination (must maintain sterility).

One good example of this is maintaining sterility of an IV set and glass solution bottle, and to equalize the internal pressure of the bottle via a vent on the spike.

Venting characteristics can be obtained by using hydrophobic membranes.

GVS has a wide range of air vent products that incorporate PTFE or hydrophobic acrylic membrane for this function.
