PureFlo® general grade polyethersulfone (PES) filter cartridges are a cost-effective alternative to standard or pharmaceutical gradecartridges for prefiltration of aqueous-based liquids.The PES membrane in an all high-purity all-polypropylene construction provides excellent chemical compatibility and competitive flow rates per surface area. No adhesives, binders, or surfactants are used in the manufacturing process.
The hydrophilic PES membrane does not require pre-wetting with IPA then flushing with water, thereby eliminating a potential source of contamination and hazardous waste. In addition, unlike hydrophobic filters such as polypropylene and PTFE, the hydrophilic membrane reduces the potential for bubble formation by not de-wetting in out-gassing fluids.
General grade PES filter cartridges are fabricated and packaged under cleanroom conditions.
PES Water Grade Cartidges
Regulatory Compliance Manufactured from materials that conform to the requirements of 21CFR Part 177 of the U.S. Code of Federal Regulations and USP Class VI Biological Test for Plastics. ISO 9001, ISO 14001 and ISO 13485 certified.
Rinse-Up Cartridges will rinse-up to 18 mega ohm with a minimum of DI throughput. (Pre-rinsing is available on standard biological and pharmaceutical grade PureFlo® PES filters.) Sanitizing Agents Cartridges may be sanitized by autoclaving or in place with common chemical sanitizing agents.
