Cytiva's Whatman™ 28-9322-36 Vivaspin™ 500 Protein Concentrator Spin Column, MWCO 50000, Polyethersulfone, Storage Conditions: 4-30°C

Vivaspin™ spin columns are designed for fast, nondenaturing concentration of biological samples by membrane ultrafiltration. High recovery rates – Up to 30-fold concentration of the sample can be achieved, with recovery of the target molecule typically exceeding 95%. Sample protection – the patented Vivaspin dead-stop technology ensures samples cannot be concentrated to dryness and enables direct concentrate recovery. Ease-of-use – one-step sample concentration in a single tube, for minimal sample handling and reduced sample loss. pH compatibility – for a broad range of pH 1 to 9. High flow rates – and minimal membrane blockage through the vertical polyethersulfone (PES) membrane design. Minimal protein adsorption – thanks to the Vivaspin™ polycarbonate tube design. Download the Vivaspin protein concentrator data file to learn more and to determine the right MWCO (molecular weight cut-off) and volume for your enrichment study. Spin column protein concentration – how does it work? Vivaspin sample concentrators cater to scientists working with sample volumes ranging from 100 μL to 20mL, with a range of MWCO values from Mr 3000 to 100 000. An upper compartment contains sample and the lower compartment separated by a semipermeable membrane. Centrifugation is applied to force solvent through the membrane, leaving a more concentrated sample in the upper chamber. Tip: To maximize recovery of your sample, select a MWCO at least 50% smaller than the molecular size of the target molecule. Still not sure what MWCO and volume are right for you?
