The centrifuge works using the sedimentation principle, where the centrifugal acceleration causes denser substances and particles to move outward in the radial direction. At the same time, objects that are less dense are displaced and move to the center. The mini centrifuge has three different rotors sizes, which rotate at highest RPM of 14000. It used for separation of several sample (Broth, DNA, RNA, Protein etc.) based on its sedimentation rate.
