The CRT-PES Series Biological Grade Filter Cartridges are IFP’s most advanced biological-grade solution, designed for high-end biopharmaceutical filtration where reliability and sterility are critical. Built with a hydrophilic PES (polyethersulfone) membrane, these cartridges provide absolute-rated retention validated by microbial challenge testing, making them the gold standard for serum and protein-based processing.

Their low protein-binding properties ensure maximum recovery of sensitive biomolecules, while broad pH compatibility (1–14) supports demanding multistage filtration setups. Pre-rinsed with pyrogen-free water, CRT-PES cartridges eliminate pre-wetting steps, reduce contamination risks, and integrate seamlessly into blood serum clarification, intermediate polishing, and biological-grade filtration.

Technical Data Sheets

Fit of IFP CRT Cartridges with Filter Housings

The choice of cartridge end cap significantly impacts sealing performance, pressure rating, and fluid distribution. The 226 O-Ring Fin (Code 7) is the most secure and widely used in critical applications, while DOE (Code 0) remains an older technology; its use is limited mainly to non-sterile processes.

End Cap Type Housing Connection Details
226 O-Ring Fin (Code 7) Most Popular - Highest Pressure Rating Recessed 226 O-ring groove with locking tabs and center receptor for fin Offers the most secure fit with dual O-ring compression and bayonet locking tabs. The integrated fin aligns the cartridge, enhancing pressure stability and promoting even solution distribution.
222 O-Ring Flat (Code 2) Recessed 222 O-ring groove with flat bottom The housing head features a precision-machined cavity to fit the 222 O-ring, ensuring tight axial compression. Uses a flat receptacle-no locking tabs.
226 O-Ring Flat (Code 6) Recessed 226 O-ring groove with flat bottom Features a wider, deeper groove for 226 O-rings. Provides enhanced sealing over 222 but lacks bayonet lock or fin alignment.
Flat Gasket (Code 0) Least Popular - Lowest Pressure Rating Flat knife-edge or gasket seat at both ends Cartridge is held by compression plates or spring caps. No O-rings or locking tabs-best for low-pressure, general-purpose filtration.
