Kärcher PES Cartridge Filter 2.889-219.0, 10 inch, 0.2 µm, Sterile Filtration

The Kärcher PES Cartridge Filter 2.889-219.0 is a high-performance pleated cartridge filter designed for sterile filtration in biopharmaceutical applications. Constructed with a polyethersulfone (PES) membrane and polypropylene hardware, this filter offers excellent chemical compatibility and low extractables. With a pore size of 0.2 µm and a filtration area of 0.7 m², it ensures reliable bacterial retention and integrity testability. The 10-inch length and 226 O-ring with fin (bayonet) end cap configuration make it compatible with standard filter housings.

Advantages

This filter provides high flow rates and throughput due to its large filtration area and pleated design. It is autoclavable, steam-in-place (SIP), and gamma irradiatable, offering flexibility in sterilization methods. The low extractable levels and USP Class VI compliance make it suitable for critical applications such as cell culture media and buffer filtration.
