Standard Regenerated Cellulose (RC) Membrane:


Dry Spectra/Por® 1-5 Dialysis Tubing & Trial Kits


Standard Grade Regenerated Cellulose (RC) is a clear, flexible and sturdy dialysis membrane with a "looser" molecular selectivity. This economical membrane is ideal for a broad range of applications in which there is a significant size difference between the MW species being separated; including sample prep, desalting, buffer exchange, pH change, protein purification, etc. Offering a good chemical compatibility, Standard Grade RC can be used with dilute strong acids and bases, concentrated weak acids and bases, most alcohols and some mild or dilute organics, including DMSO. Standard RC can tolerate pH 2 - 12 and temperatures 4-121 °C.

Spectra/Por® 1 - 5 Standard RC Dry Dialysis Tubing

Spectra/Por ® 1 - 5 Dry Standard RC Dialysis Tubing is packaged dry for handling and storage convenience. The tubing is available in 15 m/roll and 30 m/roll to provide better economy for applications requiring larger amounts of tubing. Most of the dry tubing rolls contain glycerin as a humectant which is easily removed by soaking 30 min in water. Some tubing rolls do not contain glycerin and do not require soaking prior to use.

Spectra/Por® 1 - 4 Standard RC
Ready-to-Use Dialysis Sacks

Designed for the general dialysis of larger sample volumes, the Ready-to-Use Dialysis Sack consists of a 60 cm length of Spectra/Por 1, 2, 3 or 4 tubing, sealed at one end with a Spectra/Por Closure and a funnel attached to the other for easy filling. Unlike the Spectra/ Por 1 - 5 Dry Dialysis Tubing and Trial Kits, the Spectra/Por Dialysis Sacks are pre-soaked in water to hydrate the membrane and remove the glycerin; making them ready-to-use and more convenient. The dialysis sacks are packaged wet in a preservative solution of 0.05% sodium azide. To use simply unroll, rinse, fill, apply closure and cut tubing.
