Bacterial Air Vents

Economical, Disposable Depth
Filter for Venting Applications

• Hydrophobic filter prevents the passage of aerosols, protecting equipment and staff
• Versatile - Can be used for in-line barrier on culture vessels or for bioisolation of vacuum sources
• High pressure rating ensures product integrity during pressure surges

• Use as a vent device for receiving vessels and small isolation or environmental chambers
• Recommended for small-volume venting and degassing
