25mm 0.22μm PTFE Syringe Filter Capsules For Liquid Prefiltration
Description of Liquid Prefiltration
WECHENFIB PTFE(polytetrafluoroethylene)-Syringe Filter with excellent solvent resistance and chemical inertia, can filter organic solvents, aqueous solutions, gases, etc. It is suitable for highly corrosive solutions, such as strong acids, alkali, organic solvents and strong oxidizing solutions.
The hydrophobicity of PTFE membrane is also commonly used for the removal of dust, particles, aerosols and bacteria in air and gases. Available in a variety of pore sizes (0.22μm/0.45μm/0.75μm) and diameters (13mm/25mm/33mm) for reliable removal of particles and microorganisms from solutions and gases. The filter housing is made of PP (polypropylene) and is compatible with harsh chemical solvents and acid and base solutions.
