Vivaspin® centrifugal concentrators are disposable ultrafiltration devices for the concentration of biological samples. Vivaspin® 500 centrifugal filter units offer a simple, one step procedure for sample concentration with volumes from 5 to 500 µl. They can effectively be used in fixed angle rotors accepting 2,2 ml centrifuge tubes.
- 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
The patented vertical membrane design and thin channel filtration chamber (US 5,647,990), minimises membrane fouling and provides high speed concentrations.
