PRODUCT DESCRIPTION
Sterlitech PTFE (Teflon) 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.
