Product Details
Sterile Venting PTFE Membrane Filters with Optional Support Backing
PTFE membranes are used in a variety of healthcare applications
such as the venting in IV filters,spike vents and transducer
protectors, protecting medical devices, equipments and sensors from
fluids , aqueous aerosols and contamination.
PTFE membranes are naturally hydrophobic with excellent chemical
resistance, making them the ideal choice for sterile venting of air
and gases, non-aqueous solvents, acids, and aggressive fluids. In
the biotech and pharmaceutical industry, PTFE membranes are used in
filtration of strong acids and aggressive solutions, venting of
gases. PTFE membrane filters are also used for the filtration of
corrosive solvents and acids, to which other filter types are not
resistant because of its excellent chemical compatibility with pH
tolerance ranging from 1 to 14.
We offer PTFE membranes without support which has superior thermal
stability,specifications as following,
