SLF-L - Hydrophobic Polytetrafluoroethylene (PTFE) Membrane Cartridge Filter
Masterfilter SLF-L hydrophobic PTFE filter cartridges are composed of hydrophobic PTFE membrane. Its features include exceptional organic and inorganic corrosion resistance and inherently hydrophobicity. They are highly recommended for the pre-filtration and sterile filtration of strong solvents, highly corrosive fluids and strong oxidant fluids.
