Propor LR

PROPOR LR filters have been specifically designed for high flow and effective removal of Ralstonia pickettii and other diminutive organisms.

Propor LR

A number of studies have concluded that not all microorganisms are removed by 0.2 micron rated “sterilising” grade membranes under all conditions. PROPOR LR filters use a 0.1 micron rated membrane, which can remove diminutive organisms, whilst maintaining flow rates typical of a 0.2 micron filtration system.

Ralstonia pickettii is one organism that has frequently been shown to penetrate a 0.2 micron rated membrane and is a common contaminant in purified water systems. PROPOR LR filters have been validated directly against the removal of Ralstonia pickettii.

Features & Benefits

  • Fully correlated against Ralstonia pickettii and integrity testable
  • Increases retention efficiency whilst maintaining existing 0.2 micron rated system size
  • Up to 2.5 times higher flow rate than competitive 0.1 miron rated filters
  • MURUS and DEMICAPs can be gamma-irradiated and autoclaved
