    Ultrafiltration Vial

    From: $37 Sizes: 5 itemsCatalog #: 22004, - 22018View allHide

    We offer centrifugal ultrafiltration devices with two molecular weight cut-off options: MWCO=10 kD (10K) and MWCO=3 kD (3K) for simple spin-column purification of proteins or other molecules by size separation. The ultrafiltration membrane allows molecules with molecular weight smaller than the cut-off to pass through into the filtrate collection tube, while molecules larger than the cut-off retained on top of the membrane.
