Glass Fiber Filter Cartridge

Glass Fiber Filter Cartridge

Glass Microfiber Cartridges are highly retentive adsorption depth filters designed for removing colloidal & viscous contaminants in vaccines and culture media. The construction is with a high temp PP resin for longer life in elevated temperatures. The borosilicate microfiber media with polypropylene construction provides excellent chemical compatibility and superior flow. Featured by high dirt holding capacity and excellent particle retention ability.

This positive zeta modified glass fiber media used in removal of contaminants such as colloids, lipids, protein aggregates and particles for biopharmaceuticals liquids. These filters can effectively protect the final cartridges to extend the service life. No adhesives or surfactants are used in the manufacturing process. The borosilicate microfiber is "non-fiber releasing."

Sealing technology Thermal Bonding, No Adhesives, binders or surfactants are used in the manufacturing process. Filter cartridges are 100% Integrity tested prior to release ensures consistent performance to specification. Advanced Pleat Technology construction allows maximum fluid and contaminant access to filter surface area for highest throughput. The all-polypropylene construction provides excellent thermal and chemical compatibility with low and high pH chemicals.
