Hydrophilic PTFE Membrane

Cobetter hydrophilic PTFE membrane is made of pure PTFE membrane bonded to a polypropylene non-woven support. The extreme chemical compatibility (pH 1-14) makes it an ideal material for filtration of almost all solvent, acids and alkaline solutions, and organic-based aqueous samples, and is commonly used for HPLC solvents sample preparation. The membrane is super-clean, promises low residual contamination added to the flux during the clarifying process, ensuring the analysis is not disturbed and the results are accurate.    

Cobetter could supply the hydrophilic PTFE membrane in discs or rolls. We are equipped with precious die cutting machines to meet your customization requirement. Our application experts could help you with product designing and membrane welding process.
