Winstar Series Hydrophobic PTFE Syringe Filters

Hawach WINSTAR PTFE syringe filters with pore size of 0.22μm are purple, and syringe filter with pore size of 0.45μm is orange. PTFE syringe filter is widely used in biological, chemical, electronics, medical and other fields.

Description of 0.45 μm PTFE Syringe Filter

PTFE syringe filters are automatically produced by ultrasonic welding, 100,000-level purification workshop, HPLC, IC and integrity testing support, to ensure the stability and reliability of product quality.

Polytetrafluoroethylene (PTFE) is an effective filter for solvent chemicals and other non-aqueous solutions. Wide range of chemical compatibility, strong chemical stability, and inert PTFE membrane, especially suitable for the filtration of corrosive, strong acid, and strong alkali chemicals. Ethanol and water can also be added to make it hydrophilic. Hawach has two port sizes of disposable syringe filter Teflon are 0.22 μm and 0.45 μm.

0.45 μm PTFE syringe filter membrane is made of PTFE, which is completely natural and permanently hydrophobic. Even under a very low-pressure difference, it can ensure the unimpeded passage of moist air or other gases, while the aqueous solution cannot pass through. Its performance is just the opposite of that of the disposable PTFE hydrophilic filters membrane. PTFE syringe filter 0.22 micron membrane has strong chemical compatibility, and it can filter almost all organic solvents and strong corrosive chemicals. When the water phase solution must be filtered with PTFE membrane, it must be pre-soaked with ethanol or isopropanol before the water phase solution can be filtered.
