✅ Absolute-Rated Filtration for Critical Processes
With a precision rating of 0.22 µm, this cartridge ensures effective removal of bacteria, colloids, and fine particles, meeting the strictest sterility and clarity standards.
✅ Hydrophilic or Hydrophobic PTFE Options
Hydrophilic PTFE enables rapid wet-out and water-based liquid filtration without pre-wetting, ideal for pharmaceutical liquids, biologicals, and beverages.
Hydrophobic PTFE excels in gas and solvent filtration, offering reliable water intrusion protection in sterile air and vent filtration.
✅ Superior Chemical and Thermal Resistance
PTFE offers unmatched compatibility with strong acids, bases, oxidizers, and organic solvents. Maintains mechanical strength and performance in aggressive environments and elevated temperatures.
✅ Sterilization-Friendly
Supports multiple autoclaving cycles and SIP sterilization, reducing replacement frequency and operational costs in sterile processes.
✅ High Flow Rates, Low Pressure Drops
Optimized pleated geometry and PTFE’s inherent low resistance support high flow rates while maintaining minimal pressure loss.
✅ Long Service Life
Durable membrane structure resists rupture and tearing under pressure variations and pulsed flow, ensuring longer operational uptime.
