Compact Vent Filter Cartridge for Laboratory & Small Batch Processes


This series of Compact Vent Filter Cartridge is designed for laboratory and small-scale production use. Manufactured with heat-sealing technology to eliminate adhesive contamination, they provide secure sealing with ultra-low extractables. Their robust yet compact construction withstands high-temperature sterilization, while the disposable design ensures operational safety. Ideal for protecting sensitive equipment from particulate and microbial contamination in applications such as cell culture, bioreactors, and vacuum systems.


APPLICATIONS

• Cell Culture Gas Treatment: Provides balanced, clean gas environment for cell growth and metabolism processes

• Vacuum System Protection: Effectively protects vacuum pumps and related equipment from particulate and liquid intrusion

• Bioreactor Inlet Filtration: Removes microorganisms and particles from gas streams to maintain optimal bioreactor conditions

• Precision Instrument Protection: Provides reliable intake air filtration for sensitive electronic equipment and analytical instruments

• Laboratory Small-scale Processes: Suitable for various gas and liquid filtration needs in R&D and small-scale production



BENEFITS OF  COMPACT VENT FILTER CARTRIDGE

• Clean Sealing Technology
