Dialysis Tubing and Membranes

Dialysis membranes from Repligen include biotech-grade and standard-grade regenerated cellulose (RC) and biotech-grade cellulose ester (CE) membranes, with GMP customization options, for use in both lab-scale and process-scale operations. 

Standard Grade Dialysis Tubing and Membranes 

Standard Grade Regenerated Cellulose (RC) is a clear, flexible and sturdy dialysis membrane with a broader molecular selectivity.

  • Wide chemical compatibility
  • Use with dilute strong acids and bases, concentrated weak acids and bases, most alcohols and some mild or dilute organics, including DMSO
  • Standard RC can tolerate pH 2 - 12 and temperature 4 - 121°C. 
  • 4 membrane configurations: Dry rolled tubing, Pre-wetted (ready-to-use) tubing, Pre-treated (cleaned) tubing and Single-layer flat sheets

    Biotech CE Dialysis Tubing and Membranes

    Biologically inert and ultra-pure, Biotech CE is available in the largest selection of concise MWCOs (0.1 - 1000 kD) and sizes to provide better molecular separation for desalting, isolating ionic species and macromolecular purifications.

    • Moderate chemical compatibility
    • Generally tolerates weak or dilute acids and bases and mild alcohols with only a slight change to the MWCO
    • More sensitive to harsh conditions and solvents
    • Exposure to most organic solvents may damage CE membranes
    • Use with pH 2-9 and temperature 4-37°C
    • Available in 10m/roll tubing and trial size dialysis kits (1m)
