Vivaspin® concentrators are disposable ultrafiltration devices for the concentration of biological samples of 0,4 to 2 ml.
- High retentate recovery >90%
- Vertical membrane design for ultra-fast concentration
- Safe sample concentration due to dead-stop volume
- Convenient concentrate recovery by pipetting
- Volume graduation for easy reading/monitoring
Vivaspin® 2 can effectively be used in swing bucket or fixed angle rotors accepting 15 ml centrifuge tubes. The patented vertical membrane design and thin channel filtration chamber (US 5,647,990) minimises membrane fouling and provides high speed concentrations, even with particle-laden solutions. Vivaspin® 2 combines the speed of the classic Vivaspin® products with low internal surface and membrane area in order to achieve superior recoveries from very dilute solutions.
