Vent Filters
Vent filters made of hydrophobic membranes are commonly used in air or gas applications and for venting of bioreactors, fermentation tanks, and carboys. The important considerations when selecting a gas or vent filter are air flow rate and particulate or microorganism retention. The build-in membranes must provide sufficient surface area to accommodate the air flow required by the system. Cobetter offers a broad portfolio of vent filters with effective filtration areas range from 7.3 to 20 cm².
Overview
What is a Vent Filter?
A vent filter is a compact, sterile filtration device designed to protect systems from airborne contaminants while allowing gas exchange. It consists of a hydrophobic membrane (e.g., PTFE or PVDF) housed in a polypropylene devices, commonly used in bioprocessing, pharmaceuticals, and chemical storage.
Applications
- Bioreactor Venting: Prevents contamination while allowing CO₂/O₂ exchange.
- Sterile Media Storage: Maintains sterility in tanks during fluid transfer.
- Solvent Storage Tanks: Filters airborne particulates and moisture.
- Fermentation Tanks: Controls microbial ingress in beer/wine production.
