Hydrophilic PTFE Membrane

Hydrophilic-PTFE-Membrane-3级-海报.jpgCobetter hydrophilic PTFE membrane is made of pure PTFE membrane bonded to a polypropylene 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. The membrane is super-clean, promises no residual contaminations added to the flux during the clarifying process, ensuring the analysis is not disturbed and the results are accurate.
