Cytiva Vivaspin™ 6 Sample Concentrators

Description

• Up to 30-fold concentration of the sample can be achieved with recovery of the target molecule typically exceeding 95%
• Patented dead-stop technology ensures that samples cannot be concentrated to dryness and enables direct concentrate recovery
• Accept sample volumes from 100μLto 20mL, with a range of molecular weight cutoff values from M r 3000 to 100,000 Vertical polyethersulfone semi-permeable membrane separating upper and lower chamber resists blockage and tolerates high flow rate Centrifugation forces solvent through membrane, leaving concentrated sample in the upper chamber Compatible pH range: 1 to 9 Active membrane area: 2.5cm 2 For maximum recovery, select a MWCO at least 50% smaller than the molecular size of the species of interest.
