Vivacell 100 is a disposable ultrafiltration unit for the concentration of samples up to 98 ml that can be used either in a centrifuge or for pressure filtration. Vivacell 100 thus combines the ease of use of centrifugal devices with the flexibility and control provided by pressurized ultrafiltration cells. Vivacell 100 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 250 ml bottles). 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 350 µl will prevent concentration to dryness.
