Venting and Gas Filtration

Venting and gas filtration is an essential part of laboratory operation. Venting may be as simple as a passive equilibration of gasses from a culture flask to active filtration of a gas into a bioreactor. Vent filters, whether disposable filter units or hardware with disc filters, can be useful for: 

• Equilibration of gasses generated during normal cellular growth and metabolism
• Protecting aspirators, vacuum pumps and house vacuum lines from aerosols or liquid intrusion
• Filtering air/gas into equipment
• Filtering air/gas of unwanted microbes and particulate to maintain the proper environmental growth conditions in a bioreactor
• Protecting sensitive electronics from aerosol or fluid damage
• Protecting the laboratory work environment form unwanted aerosol contamination    
  

The industry’s broadest portfolio of vent filters makes it easy to match filter performance to application requirements. These self-contained, compact filter devices provide high efficiency removal of airborne bacteria and particulate under dry or moist conditions. Rugged polypropylene housings have broad chemical compatibility.
