Sartorius™ Vivacell 70 PES Centrifugal Concentrators

Description

Designed for ultra-fast concentrations

• Features a vertical membrane design that minimizes fouling
• Built-in deadstop of 150μl will prevent concentration to dryness
• High flux PES membrane
• High retentate recovery > 90%

Easy to handle

• Disposable, easily assembled ultrafiltration unit
• Requires no tubing connections or stirring mechanisms
• Can be adapted to equipment availability or to specific user preferences
• Universal rotor compatibility

Total process flexibility: centrifuge or pressure filtration

• For convenience, the units are simply spun in a large capacity centrifuge (carriers accepting 250ml bottles)
• For faster concentration, the device can be pressurized with air or inert gas before centrifuging
• For better process control, gas pressure can be combined with gentle orbital shaking
• For highest simplicity, the device is pressurized and can be left standing on a bench top or in a refrigerator
