Popis
Dry RC Membranes Spectra/Por® 1, 2, 3 and 4
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
Contain low levels of impurities such as heavy metals and sulphides. Supplied dry and kept pliant by a layer of glycerol.
Spectra/Por® 1, 3 und 4: For standard dialysis, different MWCO and flat widths
Spectra/Por® 2: Membranes with higher permeability
