PTFE Membrane Filters
Description
Description of PTFE Membrane Filters
PTFE membrane filter is made of polytetrafluoroethylene ultrafine fibers by hot-melt bonding together. Difference from glass fiber membrane, PTFE filter is a kind of membrane material for deep filtration. Membrane filter disc has the following characteristics: membrane filter 0.22 μm is produced from food-grade isotactic polypropylene. No additives in the whole process; stable physical and chemical properties and good compatibility. PTFE membrane filter manufacturers provide 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. When filtering the gas, 99.9999% can retain various bacteria, bacteria, and particles above 0.01μm.
The PTFE membrane has hydrophobic properties and can filter out water in air and gas. As an absolute retentive membrane, hydrophobic PTFE membrane filters have excellent corrosion resistance and high flow rate, which are equivalent to Millipore membranes. Thin, highly porous, our PTFE disc has OEM service and their sizes could be customized.
Used for gas filtration to achieve sterility, large flux, high temperature resistance, strong acid and alkali resistance, wide chemical applicability, 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.
Hydrophobic 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. PTFE membrane filter is mostly used for the filtration of anhydrous samples, strong acids and alkalis and other corrosive solutions, HPLC sample preparation, and mobile phase sample clarification.
Like PVDF membrane filter, they are all hydrophobic membrane filters with low protein binding capacity and 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.
Advantage of Membrane Filter Disc
ISO9001 approved, membrane imported from Germany for its rare materials
100000-class cleaning working shop all ensured the high quality.
Membrane filter disc have good filterability and corrosion resistance.
Operating temperature ranges from -120°C to 260°C.
Inert to most aggressive solvents, including strong acids.
Corrosion resistance, lightweight, thermal stability, accurate detection.
Hydrophobic membrane filter prevents moisture from passing through air vents and resistant to almost all chemicals. Round disc type and roll type are both available for different applications.
Main Performance of Hydrophobic membrane filter
Resistant to strong acid and a strongly alkaline solution.
Hydrophobic membrane, high-temperature resistance.
Good chemical compatibility, resistance to most chemical solvents.
It becomes a hydrophilic PTFE membrane after treatment with ethanol or isopropanol.
Applications of PTFE Filter
