Polycap TC 36, 0.2/0.1 µm, sterile, with SB inlet and outlet This dual layer polyethersulfone (PES) membrane filtration capsules provides efficient filtration for critical aqueous solutions. 100% integrity-tested during manufacturing; results are correlated to microbial retention. Housing thermally fused (no surfactants or mold releasing agents). Integrity-testable by bubble point, pressure decay, or forward flow methods. Manufactured in clean room facilities under ISO Quality Systems. PES membrane protein adsorption characteristics: HSA 0.4 µg/cm²Insulin 2.0 µg/cm²Gammaglobulin 1.5 µg/cm². Available in sterile and nonsterile versions with a filling bell option. Polycap TC (PES) is available with and without a filling bell. The PES membrane is inherently hydrophilic, has low extractables, is biosafe, has excellent flow rates and exhibits low protein binding.
