Beschreibung

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
