  • Regenerated Cellulose Membrane Filter

    What is Regenerated Cellulose?

    Johnson Test Papers’ Regenerated Cellulose membrane is a hydrophilic, solvent resistant, low protein binding membrane. Reinforced with cellulose scrim, the low adsorption properties are Ideal for removing particulates from HPLC samples prior to injection i.e. mobile phase. These filters are essentially microporous cellulose acetate filters made without wetting agents. Easily wettable, they are compatible with almost all HPLC organic solvents such as acetone, acetonitrile and ethanol.

    Use for particle removal and degassing of solvents. RC membranes are also widely compatible with aqueous solutions in the pH range of 3 to 12 i.e. polar and medium polar sample solutions. Extractable with water are less than 1%. RC membranes exhibit low, nonspecific adsorption - good for biological sample filtration where maximum protein recovery is important. When used with a glass prefilter, RC is ideal for tissue culture media filtration, as well as general biological sample filtration.

    For additional information on OEM specific applications, Johnson Test Papers has the product breadth and flexibility to meet your needs, as well as the quality standards to help ensure your success.
