The PureFlo® SZL Series Nylon filter capsule is economically priced and designed for improved wetability in processes which require critical integrity validation testing. The unit provides excellent compatibility and superior flow per unit area as compared to other membrane capsules. The PureFlo® Nylon filter capsules have been specially designed for sterilizing in biopharmaceutical applications where bacterial retention is required. The hydrophilic nylon membrane does not require pre-wetting agents, thereby eliminating a potential source of contamination. The nylon membrane is a low protein-binding media to improve your process. 

The capsules were specifically designed with an easy-to wet-out structure of nylon membrane, polyester (PET) support and internal nylon end caps. The units have luer lock plugs for the vent & drain for simple and efficient evacuation of air and liquid. The units are used for filtration of small to medium volumes of fluid for processing in production, laboratory and pilot runs. No adhesives, binders, or surfactants are used in the manufacturing process of these capsules. They are rinsed with pyrogen-free water to reduce extractables and speed production. All filter capsules are 100% integrity tested to ensure filter performance each and every time out of the package. The capsule can be ordered pre-sterilized.
