Polyvinylidene Fluoride (PVDF) membrane is a naturally hydrophobic, unsupported membrane, it has received great attention because of its outstanding properties including high thermal stability, excellent mechanical strength and chemical resistance, which makes it has good resistance to organic solvents, corrosion, oxidation and withstand solutions of pH 2-10.

Cobetter Polyvinylidene Fluoride (PVDF) filter is available in Hydrophobic version or Hydrophilic version(after hydrophilic treatment). The PVDF membrane is produced with high porosity and optimized porous structure, it is an essential membrane in various industries, for example Medical, Laboratory,Food & Beverage, Pharmaceutical, etc.

The Hydrophobic PVDF membrane with excellent hydrophobic ability, fast air flow rate and professional general /sterile filtration capability, easy for assembling as unnecessary to distinguish the front and back side, can be ideally used as a PVDF venting membrane filter or air filtration/sterilization for medical devices or diagnosis assay.

Also hydrophobic PVDF membrane can be used as a carrier media of biosensors or a transfer membrane for protein blotting applications (Western Blot / ELISPOT). The optimized porous structure and high binding capacity for protein of Cobetter hydrophobic PVDF membrane makes it easy to access bound proteins and remove unbounded probes. The low background for fluorescent blots of PVDF membrane significantly increases signal-to-noise ratios for high sensitively in quantitative, multiplexing applications.

The Hydrophilic PVDF membrane with very low protein binding and high flow rate features, is ideal for clarification, pre-filtration and sterile filtration of fluids such as water, diagnostic reagent, buffer, cell culture medium, ophthalmic solution, blood products/serum, etc, offering efficient bacterial and particulate retention.

Also the hydrophilic version PVDF membrane are popular in the usage of syringe filter, funnel filter, vacuum filter and sterility testing devices applications for particles removal, sample preparation or general filtration,etc.
