Sartorius Sartofluor LG?

The Ultrafilter PF-PT-F is the direct equivalent for the configurations listed below. PTFE pleated membrane (single layer).

What it is: Sartofluor LG: ePTFE membrane with filtration area optimized for liquid (solvent) filtration rather than gas/air. Pre-wetting required since PTFE is hydrophobic.

Use for: Sterile filtration of solvents (alcohols, ketones, acetonitrile, etc.). Aggressive acids and bases where PES/Nylon fail. Process intermediates where solvent chemistry rules out all other sterilizing membranes.
