Repligen Spectra/Por 4 Standard Regenerated Cellulose (RC) Dialysis Tubing, 75 mm Flat Width, MWCO: 12-14 Kd (12, 000-14, 000

Repligen 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 to 12 and temperatures 4 to 121°c.

spectra/por® 4 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 minutes in water. Some tubing rolls do not contain glycerin and do not require soaking prior to use.
