Repligen Biotech Ce Dialysis Membranes, 31 mm Flat Width, MWCO: 0.5 To 1.0 Kd (500 To 1, 000 D)

Repligen Biologically inert & ultra-pure, biotech cellulose ester (ce) membrane offers the largest range of concise mwcos (100 - 1, 000, 000 daltons) for desalting, isolating ionic species and macromolecular purifications. Biotech ce membrane is more sensitive to harsh conditions and solvents and generally tolerates weak or dilute acids & bases and mild alcohols with only a slight change to the MWCO. Exposure to most organic solvents may damage ce membranes. Use with pH 2-9 & temp 4-37°c.

• 9 mwcos ranging from 100 - 1, 000, 000 daltons
• rigidly controlled porosity for better selectivity & separations
• ultrapure with no trace heavy metals & sulfides
• does not interfere with macromolecular activity & function
• 4 tubing flat-widths (diameters) for a range of sample volumes
• no glycerin removal or pretreatment required
• economy packaging provides a 10-meter supply of a particular ce tubing MWCO & flatwidth to meet the demands of ongoing & frequent dialysis applications

specifications:
