        Polytetrafluoroethylene (PTFE) Membrane for Environmental Monitoring

        GVS Laminated PTFE filters are made of a polytetrafluoroethylene polymer (PTFE) laminated to a polypropylene support for improved durability and easy handling.
        These filters are chemically compatible with strong acids and most aggressive solvents such as alcohols.

        PTFE (fine powder resin) is expanded into a 3-dimensional web-like structure called PTFE which creates billions of microscopic pores.
        This structure utilizes the inherent hydrophobic (water-resistant) and non-stick nature of PTFE to allow removal of particulate captured on the membrane surface.

        Property

        PTFE allows air to pass easily through the membrane while collecting particulate as small as 0.1 micron on its surface. PTFE membranes provide device manufacturers with a consistent, temperature and chemical compatible barrier to microbes and particulate matter.

        The optimal combination of air flow and water entry pressure adds value to most device designs. Inherently hydrophobic, PTFE membranes will not absorb moisture from air or gases, making it ideal for venting applications, phase separations and aerosol samplings.

        Laminated PTFE filters can be used to filter aqueous solutions when prewetted with methanol.
        They are autoclavable up to 130°C (260°F).
