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

Repligen’s Standard Grade Regenerated Cellulose (RC) membrane is available as dry rolled tubing as an economical and versatile option for general dialysis applications in which there is a significant size difference between the molecular weights of the species being separated.

SpectraPor 1-5 dry standard grade (RC) dialysis tubing and 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.

Consider Customized SpectraPor 1-5 dialysis tubing specifically for GMP multi-batch and Large Volume Dynamic Dialysis.
