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.
