Description
Sample kit Spectra/Por® 3 regenerated cellulose is a dialysis membrane kit specified with a molecular weight cut-off (MWCO) of 3500 and a flat width of 18 mm. Regenerated cellulose membranes are standard tools for buffer exchange, desalting and removal of low-molecular-weight solutes while retaining peptides, small proteins and similar macromolecules. The kit format supports evaluation of Spectra/Por® 3 before scale-up to bulk tubing. Delivered as one unit weighing 0,100 kg, it is practical for protocol scouting in biochemistry, biophysics and analytical sample preparation. Offered by manufacturer REPLIGEN, the membrane belongs to established dialysis hose systems used across filtration and separation laboratories. The narrower 18 mm width suits smaller sample volumes, and the 3500 MWCO provides tighter retention than higher-cut-off grades. Suitable for research teams refining dialysis conditions, comparing Spectra/Por® grades or validating clean-up steps prior to chromatography, concentration or downstream analysis.
This article belongs on Ultrafiltration & concentrators, in Filtration.

Questions about Sample kit Spectra/Por® 3,reg. cellulose, MWCO 3500, width 18 mm, 1 unit(s)
What is this article?
Sample kit Spectra/Por® 3,reg. cellulose, MWCO 3500, width 18 mm, 1 unit(s) is the article on this page. Luminix Health distributes REPLIGEN for laboratory use. It sits in Ultrafiltration & concentrators, inside Filtration, in Lab consumables.
An ultrafiltration device holds back macromolecules above a stated molecular-weight cutoff and passes salts and water. It concentrates a protein or exchanges its buffer. The cutoff, the volume and whether it is a centrifugal device or a stirred cell are the specification. A 0.2 µm syringe filter does not do this.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
