SpectraPor® 7 RC dialysis tubing is chemically treated to specifically minimize the heavy metals and sulfur compound impurities inherent to all regenerated cellulose membranes that could otherwise interfere with protein function, enzyme activity or molecular purity. SpectraPor® 7 is packaged wet in a 0.05% sodium azide solution and only requires a quick rinse to remove the preservative. All Standard Grade RC membranes carry no fixed charge, exhibits low adsorption and have 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.
