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.

PTFE membrane is a thin, highly porous film that behaves as an absolute retentive membrane. Their inherently hydrophobic nature make PTFE membranes ideal for applications such as filtering gases, aqueous aerosols, protecting vacuum pumps, or sterile venting fermentation tanks. PTFE is inert.

PVDF membrane filter's biggest feature is very low protein adsorption, and the PTFE filter can also be used to filter gas. PVDF filter is commonly used for purification during sterilizing or clarifying procedures. Sterile PVDF filter membrane are often used for biological sterilization filtration after hydrophilic treatment.

Hawach Scientific Co.,Ltd is a leading membrane suppliers, which provides customers with one-stop shopping, marketing strategies, and laboratory filtration product solutions.As a professional membrane filter manufacturers, Hawach has the strong technical strength and has a group of advanced and modern production equipment, mainly producing laboratory membrane filter.

Nylon membrane syringe filters may not be suitable for all samples and are ideal for near neutral pH aqueous solutions and compatible nonaqueous solvents. For samples composed of acids and bases, hydrophilic PTFE membrane syringe filters and PES membrane syringe filters may be considered.

The 0.5 μm pore size is normally used. Air and gas filtration use the hydrophobic characteristics of PTFE membranes and their ability to stop aqueous aerosols. Usual pore sizes are 0.2 μm and 0.5 μm. Venting of vacuum manifolds, fermentation vessels, and sterile filtrate tanks and containers utilize PTFE 0.2 μm membranes.
