Our Whatman hydrophobic integral venting filters range consists of Polyvent and Sterivent options. Polyvent and Sterivent vent filters are available in disc and capsule formats ranging from 25 mm discs to large-size capsules. Our HEPA-VENT and HEPA-CAP vent filters range with glass fiber filter media available as 50 mm discs and in three capsule sizes to enhance venting applications. Many of the capsule vent filters come with a variety of end fittings for easy connections and enhanced security. Whatman venting filters are products for air and gas filtration from vessels or tanks made to prevent contaminants such as bacteria or particulates access to the vessel. Hydrophobic vent filters with PTFE membrane work bidirectionally to keep the product inside the vessel and keep contaminants out when draining or filling vessels like fermentation tanks. Vent filter with glass fiber media and HEPA retention allows clean air to pass in and out of vessels such as incubators providing sterile venting and high air flow rate.
