Membrane Filters – Hydrophobic PTFE, supported

• Properties: Thin, highly porous, behaves as an absolute retentive membrane
• Supported: Polypropylene or polyester laminated to one side to improve handling
• Inert to most chemically aggressive solvents, strong acids and bases
• Thermostable

Applications

• Sterilize gases: Traps aqueous aerosols
• Air and gas venting: Allows gases to pass freely while blocking aqueous liquids, protect vacuum pumps and critical samples
• Sterilize and clarify strong acids and many other solvents incompatible with other membrane types
