Formerly from Spectrum Labs - Spectrum and Repligen are now one.
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.
Biologically inert and ultra-pure, Biotech Cellulose Ester (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)
