In-line filter capsules are particularly suitable for sterile venting of fermenters or reaction vessels to prevent airborne particles from entering or exiting the vessel. They are also well suited for tissue culture, in-line filtration, and prefiltration for suction or to serve gas in-line filters.

The Whatman HEPA-CAP Vent Filter glass fiber filter media is strengthened by dual lamination with a tough polyester monofilament. The filters are pleated to maximize surface area for high particle retention and high flow rate. The filters are available in a range of different sizes, formats and end fittings.

• Typical retention efficiency: 99.97% of all particles ≥ 0.3 µm in air
• Depth filter design: allows for high loading capacity and bi-directional flow
• Repeatedly autoclavable: at 121°C for 20 minutes (132°C max)
