SPBRMF PTFE filter cartridges are highly retentive hydrophobic PTFE membrane filters with polypropylene components that have been specially designed for critical liquid and gas sterilization applications. The PTFE membrane provides excellent chemical compatibility and superior flow per unit area for steam-in-place and hot gas applications. All filter cartridges are 100% integrity tested to ensure filter performance each and every time out of the package. PTFE filter cartridges are well-suited for critical applications where superior flow and particle or microorganism removal efficiency is required.
