Description of Hydrophilic PTFE Membrane Filters

With its filter media as hydrophilic PTFE, hydrophilic membranes filters can help users reduce costs by eliminating the need for expensive pre-wetting in the applications that require the superior temperature, chemical resistance, and low extractors of PTFE membrane. Its bubble points (0.22μm, 0.45μm) are above or equals 0.1MPa and 0.06MPa respectively, with its diameter ranging from 13mm, 25mm, 47mm to 90mm, 142mm, 293mm. Its pore size is 0.22μm, 0.45μm and chemical compatibilities are superior to aqueous, organic solvents and mixed solvents. Hydrophilic PTFE membrane filters are the strongest membrane filters for strong acid, alcohol, and so on. Our company has full range of products, diameters and pore sizes can be customized, OEM services are available as well.

Advantage of Hydrophilic PTFE Membrane Filters

Hydrophilic PTFE Membrane Filters of our company have been approved by ISO9001 and all are imported from Germany and the US to ensure high quality. The filters are manufactured in 100,000 class cleaning room with various sizes, pore sizes, and diameters available in supply for different applications. We also provide OEM service.


Hydrophilic applications
All types are available. (Roll type or round disc type)
Excellent chemical stability and particle retention
Compatible with all commonly solvent
High flow rate and low protein binding capacity
Lowest level of IC extractable, optimizing background level insensitive IC analyses

Applications of Hydrophilic PTFE Membrane Filters

It is commonly used in the following conditions:
HPLC and other mixtures of aqueous and organic solvents,
Filtration of strong acid, base, and corrosive solvent,
Natural product screening,
Aqueous solubility testing,
Total drug analysis etc.
