Standard Grade Dialysis Membranes:
Spectra/Por® 1 - 7 RC for general dialysis

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.

Float-A-Lyzer
(Note: Biotech Grade Dialysis Membrane is better suited for applications that require a better molecular selectivity and/or membrane purity.)
