Vivaspin concentrators are disposable ultrafiltration devices for concentrating biological samples. Vivaspin 2 is designed to use with samples from 500μl to 4 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 concentrations for even particle-laden solutions. Vivaspin 2 combines the speed of Vivaspin products with low internal surface and membrane area to achive superior recoveries from very dilute solutions. Vivaspin 2 offers flexibility for process optimization. With Vivaspin 2, one can directly pipet 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
