SpectraPor® 1-5 Dry Standard Grade Regenerated Cellulose (RC)
Dialysis Tubing & Trial Kits

SpectraPor® 1-5 RC dialysis tubing is packaged in dry rolls and trial kits for easy handling and storage convenience. This tubing is ideal for less critical applications requiring larger amounts of dialysis tubing. While most dry Standard RC tubing contains glycerin used as a humectant, some dry Standard RC dialysis tubing is available without glycerin and does not require soaking prior to use. Dry RC membrane has no fixed charge, exhibits low adsorption and contains trace levels of heavy metals and sulfur compounds. Standard Grade RC membrane has a 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

  • Low cost and economical membrane
  • Good chemical compatibility and operating conditions tolerance
  • Dry for easy handling and storage
  • No azide preservative solution
  • Available in rolled tubing for economy and trial kits for evaluation

Typical Dialysis Applications for Prewetted Standard RC

  • Salt removal and HPLC sample preparation
  • pH change, buffer exchange and final formulation
  • Removal of urea, surfactants and small MW impurities
  • Biopolymer and hydrogel purification (hyaluronic acid, collagen, chitosan)
  • Large volume and GMP batch process dialysis
  • Organic solvent dialysis
  • Ecological, marine and ground water studies

Biotech CE Dialysis Membranes

Biologically inert & ultra-pure, Biotech Cellulose Ester (CE) Membrane offers the largest range of concise MWCO's (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. Biotech CE Tubing is available in more economic 10 meter rolls and 1 meter length Dialysis Trial Kits.

Features and Benefits

  • 9 MWCO's 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

Biotech RC Dialysis Membranes

Biotech RC is Repligen's premium dialysis membrane crafted from a regeneration process that yields superior temperature tolerances and chemical compatibilities while maintaining the same high purity and selectivity as Biotech CE. RC membrane can tolerate concentrated-weak acids & bases, dilute-strong acids & bases, most alcohols and some mild or dilute organic solvents.

PRODUCT

Float-A-Lyzer Dialysis Device

The SpectraPor® Float-A-Lyzer® Dialysis Device is a unique and leak-proof, ready-to-use device designed for easy and convenient dialysis of small sample volumes from 1 – 10 ml. The device is made with high purity Biotech Grade Cellulose Ester (CE) membrane in 9 MWCOs from 0.1-1,000 kD. Screw cap lid and included pipette allow for easy loading, in-process testing and sample retrieval without the risk of needle punctures. Biotech CE membrane exhibits a fair chemical compatibility and tolerates pH 2-9 and temp 4-37 °C. Exposure to most organic solvents is not recommended and should be confirmed on the Repligen Chemical Compatibility table.

Features

  • 3 ready-to-use volume sizes (1 ml, 5 ml & 10 ml)
  • 9 Concise MWCO’s for better selectivity & separations
  • High purity Biotech Cellulose Ester (CE) membrane
  • Leak-proof and color-coded screw cap
  • Complete with floatation ring and pipette included

Typical Dialysis Applications for Float-A-Lyzer® Dialysis Devices

  • Drug dissolution and controlled release studies
  • Salt, urea, surfactant and cesiuam removal
  • HPLC sample preparation
  • pH change, buffer exchange and final formulation
  • Purification of Protein, DNA, plasmids, macromolecules, nanoparticles and liposomes
  • Biopolymer purification and removal of monomers
  • Enzyme activity and ligand binding studies
  • DNA and Protein electroelution
