Sartorius™ Vivaspin™ 2 Centrifugal Concentrator with Cellulose Triacetate (CTA) Membrane

Description

• Vivaspin concentrators are designed for the concentration or diafiltration of initial sample volumes up to 3 mL and can be used with swinging bucket or fixed angle rotors that accept 15 mL centrifuge tubes
• Vivaspin's patented vertical membrane design and thin channel filtration chamber (US 5,647,990) minimize membrane fouling and provide high-speed concentration for even particle-laden solutions
• The speed of Vivaspin products combined with low internal surface and membrane area allow superior recovery from very dilute solutions
• The Vivaspin 2 also offers flexibility for process optimization: one can directly pipette the concentrate from the dead stop pocket (built into the bottom of the concentrator) or reverse-spin the concentrate into the recovery cap (which can be sealed for storage)
• Either method results in near-total concentrate recovery
• High retentate recovery >90% Vertical membrane design for ultra fast concentration Universal rotor compatibility Safe sample concentration due to dead-stop volume Convenient concentrate recovery by pipetting Optional re-spin for concentrate recovery Volume graduation for easy reading/monitoring
