Strainrite’s PRMXE 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 polyethersulfone 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.
These cartridges meet USP Biological Reactivity Test, in vivo for class VI-121°C plastics. Sterilizable using industry recognized and accepted methods.


  • High surface area membrane offers excellent life and flux rates, while providing absolute-rated filtration
  • Absolute-rated membrane provides reliable, consistent and repeatable filtrate quality
  • Low pressure drops yield higher flow rates and reduced processing time
  • Non fiber-shedding Polyester and Polypropylene support materials eliminate fiber migration
  • Low hold-up volumes
  • Pleat design for greater surface area, ensuring longer service life, fewer change outs and reduced operating costs per element
  • Thermally bonded construction without the use of adhesives or binders, resulting in lower extractables
  • Integrity tested
  • High strength design allowing for extended use and multi-autoclave cycles
  • All materials of construction are FDA compliant with CFR Title 21, Pharmaceutical grades are bio-safe in accordance with USP Class VI
  • Optional built-in pre-filter layer for extending membrane life and reducing filtration costs
