Mem-Pleat S

2.5” diameter
The Mem-Pleat S was developed for the filtration of process fluids that require a high degree of particle retention and/or constant bacterial barrier for effective sterilization.
Hydrophilic asymmetric polysulfone membrane ensures excellent flow rates, broad chemical compatibility, low protein binding, low extractability, high mechanical strength, and temperature resistance in a variety of applications for the biopharmaceutical, microelectronics, chemical, food and beverage industries.
The Mem-Pleat S meets USP Biological Reactivity Test, in vivo for class VI-121°C plastics. Sterilizable using industry recognized and accepted methods.


  • Highly tapered asymmetric pore structure which offers excellent flow rates and high solids loading characteristics
  • Absolute-rated membrane provides reliable, consistent and repeatable filtrate quality
  • Non-fiber shedding Polypropylene support materials eliminate fiber migration
  • Maximum pleat design for greater surface area, ensuring longer service life, fewer change outs and reduced operating costs per element
  • All materials of construction are FDA compliant with CFR Title 21, Pharmaceutical grades are bio-safe in accordance with USP Class VI
  • Thermally bonded construction without the use of adhesives or binders, resulting in lower extractables
  • Low hold-up volumes
  • Pharmaceutical and Electronics grades are integrity testable
