SpectraPor® Pre-treated Standard Grade RC Dialysis Tubing and Trial Kits

Repligen provides a high purity, clean Standard Grade Regenerated Cellulose (RC) dialysis tubing that has been pre-treated for more critical applications that could be negatively impacted by the presence of trace heavy metals, sulfur compounds and membrane adherent impurities.

SpectraPor® Pre-treated standard RC Dialysis tubing and trial kits

SpectraPor® 7 RC dialysis tubing is chemically treated to specifically minimize the heavy metals and sulfur compound impurities inherent to all regenerated cellulose membranes that could otherwise interfere with protein function, enzyme activity or molecular purity. SpectraPor® 7 is packaged wet in a 0.05% sodium azide solution and only requires a quick rinse to remove the preservative.  All Standard Grade RC membranes carry no fixed charge, exhibits low adsorption and have good chemical compatibility with concentrated-weak or diluted-strong acids and bases, most alcohols and some organic solvents, while tolerating pH 2 - 12 and temperature 4 - 121° C. Compatibility to specific solvents should be confirmed on the Repligen Chemical Compatibility Table.

Features and Benefits

  • Pre-treated to minimize membrane impurities
  • Available in large range of MWCO’s
  • Good chemical compatibility and operating conditions tolerance
  • Minimal glycerin content
  • Available in rolled tubing and trial kits for evaluation

Typical Dialysis Applications for Pre-treated Standard RC

  • Salt removal and HPLC sample preparation
  • pH change, buffer exchange and final formulation
  • Removal of urea, surfactants and small MW impurities
  • Purification of Protein, DNA, plasmids, macromolecules, nanoparticles and liposomes
  • Polymer synthesis and isolation (polypeptide, oligonucleotide, polysaccharide)
  • Enzyme activity and ligand binding studies
  • Organic solvent dialysis
