Vivacell 70
10 - 70 ml
Ultrafiltration unit for sample concentration with highest process flexibility: Centrifugation or centrifugation of pressurized units, as well as pressure filtration in stationary benchtop mode or with gentle shaking.
ivacell® 70 is a disposable ultrafiltration unit for the concentration of samples between 10 ml and 70 ml and can be used either in a centrifuge or for pressure filtration. Vivacell® 70 thus combines the ease of use of centrifugal devices with the flexibility and control provided by pressurized ultrafiltration cells. Vivacell® 70 is easy to assemble, requires no tubing connections or stirring mechanisms and 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 250ml bottles). For even faster concentration, particularly with difficult samples, the device can be pressurized with air or inert gas before centrifuging. For better process control or for handling of single samples, 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 150 µl will prevent concentration to dryness.
