PTFE Hydrophobic Membrane:PTFE membranes are chemically resistant to nearly all solvents,acids and bases. The membrane has low extractable and good thermal stability. PTFE is hydrophobic and requires pre-wetting prior to use with aqueous solvents
Polypropylene housing : Red color polypropylene housing, non-sterile
Excellent Chemical Compatibility: Filtering harsh chemicals that destory other membranes materials and ideal for aerosol sampling
