Description

Description of PTFE Membrane Filter

Hawach hydrophobic PTFE membrane filter is made of polytetrafluoroethylene ultrafine fibers by hot-melt bonding together. It is produced from food-grade isotactic polypropylene. No additives in the whole process; stable physical and chemical properties and good compatibility.

0.45um ptfe membrane filter

As a membrane filter manufacturer, Hawach provides a series of pore sizes(0.1μm, 0.22μm, 0.45μm, 1.0μm, 3.0μm, 5.0μm, 10μm), high porosity, large dirt holding capacity, recoil and high-temperature disinfection; good pressure resistance. Thin, and highly porous, our PTFE disc membrane has OEM service and their sizes could be customized.

The PTFE membrane has hydrophobic properties and can filter out water in air and gas. As an absolute retentive membrane, the hydrophobic PTFE membrane filter has excellent corrosion resistance and a high flow rate, which are equivalent to Millipore membranes.

PTFE membrane filter has excellent chemical stability, resistance to organic solvents and strong acids, corrosion resistance; high-temperature resistance, and low protein binding ability. Smooth surface, high filtration efficiency, and wide application range. Like PVDF filters, they are all hydrophobic membrane filters with low protein binding capacity and a high protein recovery rate. The chemical stability and inertness of the PTFE membrane make it suitable for corrosive organic solvents, strong acids, and strong bases. PTFE membrane is also very suitable for HPLC sample preparation.

Its natural hydrophobicity is also very suitable for air and gas sterilization. The PTFE membrane is laminated to a non-woven polypropylene support net to improve strength and workability and can be used at high temperatures up to 120ºC. The difference is that the PVDF membrane filter has strong resistance, only second to the PTFE membrane filter.

Advantages of PTFE Membrane Filter

  • ISO9001 approved.
  • 100000-class cleaning working shop all ensured the high quality.
  • The membrane filter discs have good filterability and corrosion resistance.
  • Hydrophobic membrane filter prevents moisture from passing through air vents and is resistant to almost all chemicals.
  • Hydrophobic PTFE membrane filters have round disc types and roll types are both available for different applications.
  • The operating temperature ranges from -120°C to 260°C.
  • Inert to most aggressive solvents, including strong acids.
  • Corrosion resistance, lightweight, thermal stability, accurate detection.

Main Performance of Hydrophobic PTFE Membrane Filter

Difference from glass fiber membrane, the PTFE filter is a kind of membrane material for deep filtration. The disc PTFE membrane filter has the following characteristics:

  • Hydrophobic membrane, high-temperature resistance.
  • Good chemical compatibility, and resistance to most chemical solvents.
  • Resistant to strong acid and a strongly alkaline solution.
  • PTFE filter becomes a hydrophilic PTFE membrane after treatment with ethanol or isopropanol.

Applications

  • Ordinary laboratory filtration.
  • Membrane filter disc for filtration of anhydrous samples.
  • Solvent sterilization.
  • Remove particles from the HPLC solvent.
  • Compressed air sterilization filtration.
  • PTFE membrane filter is used to sterilize gasses, vent gas from aqueous solutions, or sterilize or clarify aggressive chemicals.
  • High-purity gas filtration in the electronics industry.
  • Purify samples and mobile phases of HPLC and GC.
  • Clarifying corrosive substances, strong acids, and alkalies.
  • Quality control and sterility inspection.
  • Widely used in the fields of pharmacy, food processing, biochemistry, microelectronics, and laboratory consumables.

Mostly used for the filtration of anhydrous samples, strong acids, alkalis, and other corrosive solutions, HPLC sample preparation, and mobile phase sample clarification. Used for gas filtration to achieve sterility, large flux, high-temperature resistance, strong acid, and alkali resistance, wide chemical applicability, and suitable for fermentation tanks, carbon dioxide, nitrogen, and compressed air. When used for gas filtration, it can intercept 100% of various phages, bacteria, and particles above 0.02um.
