Description
Roti-Spin MIDI 50 kDa is a centrifugal filter unit designed for laboratory filtration and separation work that relies on controlled molecular-weight cut-off. With a stated cut-off of 50 kDa in the MIDI format, the unit supports centrifugation-based sample handling where retained and filtrate fractions need to be processed in a compact spin device. Each pack contains 12 units, giving a practical stock quantity for routine bench workflows in filtration, dialysis-related separation, and general sample preparation environments. The article belongs to the centrifugal filter units group within labware for filtration and separation and is supplied as centrifugation units ready for use in standard laboratory centrifuges appropriate to the MIDI geometry. Physical pack data list a weight of 0,140 kg for the 12-piece unit quantity, which helps with storage planning and goods receipt checks. These Roti-Spin MIDI devices from manufacturer Carl ROTH are positioned for laboratories that standardise on defined kDa ratings across a series of spin filters. Clear identification of the 50 kDa rating on the product name reduces selection errors when several cut-offs are stocked side by side. The twelve-unit pack supports both single-run experiments and small-batch processing without oversized inventory.

Questions about Roti-Spin MIDI 50 kDa, 12 units, Centrifugation Units, 12 unit(s)
What is this article?
Roti-Spin MIDI 50 kDa, 12 units, Centrifugation Units, 12 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Filtration accessories, inside Filtration, in Lab consumables.
Filtration accessories are the holders, the gaskets, the manifolds and the flasks a membrane or a Büchner setup needs. A holder for 47 mm discs does not clamp a 25 mm disc. The gasket is what actually seals.
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.
