Description of PTFE Membrane Filters

PTFE membrane filter is made of polytetrafluoroethylene ultrafine fibers by hot-melt bonding together. 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.

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.

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. It 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 filter with low protein binding capacity and high protein recovery rate and can be used for HPLC sample preparation. 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, and the 100000-class cleaning working shop all ensured the high quality.
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.
Inert to most aggressive solvents, including strong acids.
Operating temperature ranges from -120°C to 260°C.

Main Performance of Hydrophobic membrane filter

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

Applications of PTFE Filter

Solvent sterilization
For filtration of anhydrous samples
Compressed air sterilization filtration
High-purity gas filtration in the electronics industry
Clarifying corrosive substances, strong acids, and alkalies
Purify samples and mobile phases of HPLC and GC
Used to sterilize gasses, vent gas from aqueous solutions, or sterilize or clarify aggressive chemicals
