Biotech RC dialysis tubing

Biologically inert and ultra-pure, SpectraPor® Biotech CE Dialysis Membrane provides superior molecular selectivity and is available in the largest selection of 9 concise MWCO's ranging from 0.1 – 1,000 kD, whether purifying small MW solutes or isolating large macromolecules or nanoparticles. Biotech CE membrane generally tolerates weak or dilute acids & bases and mild alcohols and is compatible with pH 2-9 and temp 4-37 °C. Exposure to most organic solvents is not recommended and should be confirmed on the Repligen Chemical Compatibility table. Simply soak and rinse in DI water, apply Universal Tubing Closures and load sample.
