Sartorius Vivaspin™ 100 Disposable Ultrafiltration Units

• For the concentration of samples up to 98 mL
  • Can be used either in a centrifuge or for pressure filtration
• Combines the ease of use of centrifugal devices with the flexibility and control provided by pressurized ultrafiltration cells
• Easy to assemble
  • Requires no tubing connections or stirring mechanisms
  • Can be adapted to equipment availability or to specific user preferences
• For convenience, the units are simply spun in a large capacity centrifuge (carriers accepting 250 mL bottles)
• For better process control, gas pressure can be combined with gentle orbital shaking
• For highest simplicity of use with minimum equipment requirements, the device is pressurized and then left standing on a bench top or in a refrigerator
• The concentrator features a vertical membrane that minimizes fouling, while the built-in deadstop of 350 μL will prevent concentration to dryness.

Features:

• Easy to handle
• High flux PES membrane
• Vertical twin membrane for ultra-fast concentration
• High retentate recovery (90%)
• Total process flexibility
• Compatible with swing out rotors
