Spectra/Por 4 Regenerated Cellulose (RC) Dialysis Tubing

Spectra/Por 4 Regenerated Cellulose (RC) Dialysis Tubing

  • Available in a variety of diameters and flat widths to meet your application needs

  • Regenerated cellulose (RC) membrane for the gentle separation and purification of solutes

MWCO from 12,000 to 14,000 daltons. Similar to SPECTRA/POR 2 membranes, except thicker. Dialysis time is slower, but at much less cost.
Dialysis tubing is available in a range of nominal MWCO's for less specific separations. Use the economical-grade Spectra/Por 4 membrane for less critical general applications such as desalting and buffer exchange. All are packaged dry with 10% glycerol and contain trace levels of heavy metals and sulfur.

S/P 1 has MWCO of 6000 to 8000 Dalton
S/P 2 has MWCO of 12,000 to 14,000 Dalton
S/P 3 has MWCO of 3500 Dalton
S/P 4 has MWCO of 12,000 to 14,000 Dalton
s/P 5 has MWCO of 12,000 to 14,000 Dalton
