Hydrophilic PTFE membrane filter rolls

Hydrophilic PTFE membrane filter rolls for filtration are made of PTFE (polytetrafluoroethylene), and were drawn 2-demension. It is micro-pore film. Applied to extensive industries, including pharmacy, biochemistry, microelectronic, and lab material and etc.

Hydrophilic PTFE membrane filter rolls are Directly and indirectly related to pharmacy, brewing, manufacture of pure water and special need water, beverage and dairy, chemical reagent, biochemical reagent, air filtration of fermentation tank in microelectronic, purification and filtration in microelectronic plants, filtration and separation of antibacterial fluid, production of medicine, air conditioning of hospitals and commercial buildings.

They provide the lowest IC extractable levels and broad chemical compatibility with both aqueous and organic solutions. It removes particulates from aqueous and mild organic solvents for cleaner IC spectra. Syringe filters are available in two pore sizes and two diameters to optimize results.

*Lowest level of IC extractables, optimizing background levels in sensitive IC analyses
*Compatible with both aqueous and organic solutions, offering broad chemical compatibility and flexibility in the lab
*Each Hydrophilic PTFE membrane filter rolls lot is certified to contain low ion extractable levels
*Able to filter solutions at temperatures up to 100˚C
*Available in 0.22um and 0.45um pore sizes and two diameters to suit your application needs
