PTFE Capsule Filters

PTFE Capsule filters consistently achieve absolute filtration with low extractables. Constructed using a 100% PTFE membrane, they are especially designed for reliable general chemical and air filtration.

NOTE: We only keep a select group of capsules in stock.  If a capsule is not available for purchase please contact our sales department.   We do require a minimum of 5 units for items not in stock. 

Hydrophobic PTFE Capsule filters require alcohol prewetting prior to aqueous solution filtration.

Sterlitech PTFE filter capsules are highly retentive hydrophobic PTFE membrane filters that have been specially designed for critical applications. The PTFE membrane in an all-polypropylene construction provides excellent chemical compatibility and superior flow per surface area as compared to other membrane capsules. No adhesives, binders, or surfactants are used in the manufacturing process and all cartridges are rinsed with high purity water to reduce extractables and downtime. The hydrophobic PTFE membrane is ideally suited for aggressive chemicals such as acids, bases, and solvents. In addition, the hydrophobic membrane provides superior flow and pressure drop characteristics per surface area for gas filtration and tank venting applications. All filter capsules are 100% integrity tested to ensure filter performance each and every time out of the package. Sterlitech PTFE filter capsules are well suited for critical applications where superior flow and particle removal efficiency at 0.1, 0.2, 0.45 and 1.0 micron is required.
