Whatman PTFE Membrane Filters ‒ WTP Range

Description

Polypropylene grid support material for increased strength
Temperature resistant up to 120°C
Resistant to most aggressive acids, alkalis, and solvents
Hydrophobic membrane filters can collect aqueous aerosols

PTFE membranes are especially effective for use with aggressive solvents, liquids, and gases.

Gas sterilization* and liquid clarification

PTFE membranes are used for liquid clarification of corrosives, solvents, and aggressive fluids. Effective sample filtration is critical to prevent equipment damage. GE’s PTFE hydrophobic membrane filters are also suitable for air and gas sterilization* because of their ability to capture aqueous aerosols.
