| Chemically pre-treated RC membranes Spectra/Por® 7 Standard Grade Regenerated Cellulose (RC) is a clear, flexible and sturdy dialysis membrane. This 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 preparartion, desalting, buffer exchange, pH change, protein purification. 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 These membranes have been chemically pre-treated to remove trace levels of heavy metals and sulfide compounds. Ready-to-use membrane already equilibrated in water and supplied in 0.05 % sodium azide solution. Simply rinse away the preservative solution with DI water, load the sample and dialyze.
