Whatman 2814T Polycap HD 150, 20.0 micrometer Pore Size, Polypropylene, FNPT Inlet & Outlet, 5/pk

This heavy-duty capsule filter is commonly used for coarse clarification and prefiltration of buffers, solvents, reagents, emulsions, and process fluids. It is especially useful as a finishing or protective filtration step before reverse osmosis, ultrafiltration, or microfiltration systems.

This model features a 20.0 µm polypropylene membrane housed in a 150 mm capsule with female NPT inlet and outlet connections. It is supplied non-sterile in packs of five and is designed for high-flow processing applications.

The all-polypropylene housing, media, and support structure offer broad chemical compatibility across a wide range of pH values and temperatures. This robust design enables reliable performance with many laboratory and industrial solutions.

Yes. Polycap HD capsule filters can be autoclaved with steam at 121 °C for about 20 minutes if sterilization is required. This makes them suitable for workflows that need clean or controlled filtration conditions.

The 20 µm rating is intended for coarse particle removal and high-throughput prefiltration rather than fine sterilizing filtration. It helps remove larger particulates while maintaining very high flow rates and long service life in process applications.
