SteriPS Filter Cartridges
Single-layer PES Membrane · Sterilizing Grade

Cobetter SteriPS® Filter Cartridges are specially designed to provide superior flow rates at an economical cost. The unique construction features a high particle removal efficiency. Hydrophilic polyethersulfone membrane cartridges require no prewetting and ready to use. This assures a cost effective device while maintaining excellent performance in the beverage applications.


Features and Benefits

  • Low diffusion flow
  • Inherently hydrophilic PES membrane
  • High surface area design provides excellentlow rates and extended service life while aintaining high bacteria removal efficiency
  • Lower protein binding

Log Reduction Values are calculated using the following formula:

LRV = log 10(    total number of organisms entering the filter total number of organisms entering the filter)




Integrity Testing Parameters

The Integrity test is a non-destructive test that can be performed
by the user to ensure the filter is installed correctly and ready for operation.
