Sartorius Vivaspin™ 2 Centrifugal Concentrators: PES Membrane

Description

• Combines high speed with superior retentate recovery for concentrating very dilute solutions
• Sartorius Vivaspin™ 2 Centrifugal Concentrators: PES Membrane feature twin vertical membranes, small internal surface areas and thin-channel chambers
• Available in a range of MWCO and packaging quantities
• Vivaspin concentrators are disposable ultrafiltration devices for concentrating biological samples
• Vivaspin 2 is designed for use with samples from 500μl to 2mL in rotors that accept 15mL centrifuge tubes
• The unique design provides high-speed concentrations for even particle-laden solutions and near-total concentrate recovery
• Twin vertical membranes and optimal design for fast, safe concentration Patented twin vertical membrane design for ultra-fast processing speeds In a single spin, solution volumes up to 4mL can be concentrated up to 30x in 5–30 minutes Thin-channel filtration chamber minimizes membrane fouling and increases filtration speed Dead stop pocket built into the bottom eliminates the risk of sample filtration to dryness High-flux PES membranes feature very low protein binding and low extractables Designed for maximum flexibility and sample recovery Low internal surface and membrane area for superior recoveries from very dilute solutions Two methods for easy concentrate recovery: Directly pipet the concentrate from the dead stop pocket in the concentrator Reverse-spin the concentrate into the recovery cap, which can be sealed for storage Both methods provide near-total concentrate recovery of greater than 90% Volume graduation for easy monitoring of concentrate volume and 8μl dead-stop volume Universal compatibility with swing bucket or fixed angle rotors accepting 15mL centrifuge tubes
