Whatman HEPA-VENT is a disposable, In-Line Filter Device that will retain
99.97% of all particles greater than 0.3 µm. with a Polproplene housing and a Glass microfibre filter they are suitable for a wide variety of air filtraion tasks. They are not suitable for liquid filtration.
Whatman HEPA air filter products offer particle retention of even heavily particulate-laden air samples. Whatman HEPA-VENT filters are highly suited for applications where high retention, dirt-holding capacity, and flow rates are required. They are typically used as in-line filters during air or gas filtration in fermenters, or incubators.
Whatman HEPA-VENT in-line disk filters are convenient, disposable, light-weight filters with high-efficiency glass fiber media for maximum particle retention.
Whatman brand venting filters from Cytiva's business are available for a variety of applications. In addition to Whatman HEPA-VENT filters, The alternative Whatman HEPA-CAP capsule venting filter is available to support greater filtration volumes.
Description
HEPA-VENT is a disposable, In-Line Filter Device that will retain 99.97% of all particles greater than 0.3 µm. HEPA filter media is used throughout the Scientific, Research, and Industrial fields to provide clean/sterile air & gases.
The HEPA-VENT housing is manufactured from rugged polypropylene. The HEPA-VENT filter media is a Glass Micro Fiber (GMF) that has been laminated on both sides with a monofilament and treated to be mildly hydrophobic.
Venting
To ensure clean/sterile air passing in and/or out of vessels (mixing, filling, fermenting, storing and transporting) the GMF media provides high flow rates with low pressures. Press fit or clamp one connector (the HEPA-VENT is bi-directional) to the outlet of the vessel, the other connector is open to the atmosphere.
In-Line
Particles ≥0.3 µm will be removed from the gas/air stream by simply passing through the HEPA-VENT. The stepped hose barbs will accept tubing 6 to 10 mm (¼ to â…œ inch) ID. When using on high pressures, hose clamps should be considered.
Sterilization: Autoclave; at 121 °C (132 °C maximum) for 20 minutes. Multiple autoclave cycles may be possible. However reuse is the responsibility of the operator, who should protect the device from cross contamination and detect loss of integrity by appropriate testing. Et0 or radiation sterilization should be possible based on the materials of construction, however no specific studies have been conducted
