Single Layer Hydrophilic PES Membrane for Bio-burden Reduction

Single Layer Hydrophilic PES Membrane for Bio-burden Reduction

The Highly retentive and porous structure of these sterilizing grade membrane filters provides highly effective filtration by retaining particles and bacteria absolutely, with 100% Retention. PES membrane is inherently hydrophilic and does not require pre-wetting with IPA or flushing with DI water. This eliminates a potential source of contamination and hazardous waste. They provide the finest, most efficient and reliable performance for critical final filtration applications.


Biological Grade Cartridges are well-suited for critical applications where superior flow, microbial reduction and particle retention at 0.1, 0.2, 0.45, 0.65 and 0.8 micron are needed. The PES membrane also exhibits low protein-binding characteristics. Low protein binding feature makes it suitable for aseptic processing in biopharmaceuticals as well as food & beverages industry. 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.
