| Purification based on molecular weights |
Spectra/PorŪ 1-4 and 6 are regenerated cellulose. Spectra/PorŪ 1-4 are for separations at an approximate molecular weight cutoff. Supplied dry, they contain 10% glycerol, 0.1% sulfur and heavy metal traces. Use Spectra/PorŪ 6-7 for separations at a specified MWCO. Supplied wet in a 0.1% sodium azide preservative solution.
