Description
Sample kit Spectra/Por® 1 regenerated cellulose is a dialysis membrane kit intended for laboratory separation and buffer-exchange work at a molecular weight cut-off of 6000–8000. The flat width of 32 mm suits moderate sample volumes in research, biotech and analytical settings where controlled retention of macromolecules is required. Regenerated cellulose tubing offers a familiar, widely used membrane chemistry for desalting, concentration and dialysis against aqueous buffers. This single-piece sample kit from manufacturer REPLIGEN allows laboratories to evaluate Spectra/Por® 1 performance before scaling to larger packs. With a unit weight of 0,110 kg, the kit is convenient for method scouting, teaching labs and pilot purification steps. Typical uses include protein and peptide dialysis, removal of small-molecule contaminants and equilibration into new buffer systems prior to chromatography or assay. The defined MWCO window and 32 mm width support reproducible handling with standard dialysis closures and vessels. Spectra/Por® 1 regenerated cellulose remains a practical choice whenever a clear 6000–8000 dalton cut-off and straightforward wet chemistry compatibility are needed in routine dialysis workflows.
