Biotech CE Membrane

Dialysis tubing of highest purity.

Biologically inert and ultra-pure, Biotech CE membrane offers the largest range of concise MWCO's for desalting, isolating ionic species and macromolecular purifications. It is more sensitive to harsh conditions and solvents and generally tolerates weak or dilute acids and 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 and temperatures of 4 to 37 °C.
  • Rigidly controlled porosity for better selectivity and separations.
  • Ultrapure with no trace of heavy metals and sulfides.
  • Does not interfere with macromolecular activity and function.
  • No glycerin removal or pretreatment required.
