      Hydrophilic PTFE Membrane

      Hydrophilic-PTFE-Membrane.jpgCobetter 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.
