Description
Sample kit Spectra/Por® 2 regenerated cellulose is a dialysis membrane kit with a molecular weight cut-off (MWCO) of 12 000–14 000 and a flat width of 45 mm. Regenerated cellulose tubing is widely applied for buffer exchange, desalting and size-selective separation of macromolecules in aqueous biochemical workflows. The sample-kit format lets laboratories trial Spectra/Por® 2 performance before ordering larger membrane quantities. Supplied as one piece with a weight of 0,080 kg, it suits method development in protein work, nucleic-acid handling and other dialysis-based purification steps. This kit from manufacturer REPLIGEN fits filtration, water-purification and separation suites where reproducible MWCO behaviour is essential. The 45 mm width accommodates moderate sample volumes, while the 12 000–14 000 cut-off retains larger biomolecules and allows smaller solutes to diffuse. Ideal for research groups establishing dialysis protocols, comparing membrane grades or validating buffer-exchange conditions under controlled laboratory practice.
