refrigerated centrifuge_eppendorf.jpgA laboratory centrifuges work on the sedimentation principle, where the centripetal acceleration is used to separate substances of greater and lesser density. The rate of the centrifugation is calculated by the acceleration applied to the sample and it is typically measured in revolution per minute (RPM) or relative centrifugal force (RCF). The particle's settling velocity during centrifugation depends on the function of their size and shape, centrifugal acceleration, the volume fraction of solids present, the density difference between the particle and the liquid, and the viscosity. This centrifuge accommodates a variety of rotors like swing-bucket and high-speed fixed-angle rotors. The rotorsare available to accomodate:
1. 15 ml, 50 ml tarson round bottom/conical bottom tubes@ 11000 rpm max
2. 1.5-2 ml microfuge tubes @ 14000 max
3. standard slide box - swing bucket @ 3700 rpm max
These can be used for cell harvesting, separating cell lysates and DNA precipitation. It also provides the cooling mechanism to maintain the uniform temperature throughout the operation of the sample.
