PVDF Folding Filter Cartridge

Product Introduction：

PVDF folding filter cartridge (polyvinylidene fluoride membrane)

The PVDF folding filter adopts polyvinylidene fluoride microporous membrane, which has good chemical compatibility and extremely low protein binding properties. PVDF membrane is naturally hydrophobic and can be used for aqueous solution filtration without pre wetting after hydrophilic modification treatment. Wide chemical compatibility (especially tolerance to some ketone and ester organic solvents); It is an important filtering option in the fields of pharmaceutical and biological products, as well as electronic chemicals.

Application fields:

◎ Pharmaceutical industry: terminal filtration of biological products, blood products, vaccines, and protein based drugs

◎ Electronics industry: electronic grade chemical filtration, semiconductor wet process

◎ Food and beverage: beer, wine, juice clarification and sterilization filtration

◎ Chemical industry: precision filtration of organic solvents and chemical reagents

Product Features:
◎ Extremely low protein binding capacity (second only to PES)

◎ Chemical compatibility superior to PES

After hydrophilic treatment, it can be directly used in aqueous phase

Suitable for biological products and electronic chemicals
