Vivacell 70 combines the ease of use of centrifugal devices with the flexibility and control provided by pressurized ultrafiltration cells. Vivacell 70 is inexpensive, quick and easy to assemble, requires no tubing connectors or stirring mechanisms and can be adapted to equipment availability or to specific user preferences. For convenience, simply spin in a large capacity centrifuge (carriers accepting 250 mL bottles). For highest speed particularly with difficult samples, pressurize the device with air or inert gas before centrifuging. For more process control or for single samples, combine gas pressure with a gentle orbital shake or you can even pressurize and then leave to stand on a bench top or in a refrigerator for highest simplicity with minimum equipment requirements. The longitudinal membrane inhibits fouling, whilst the built-in dead stop will hinder further concentration when residual volume drops below 150 μL.
