Centrifugal separation technology is a new technology developed according to the state of particles in a practical centrifugal occasion. Particles of different densities, sizes or shapes settle in different centrifugation occasions, so a generally spherical inhomogeneous mixture can be separated by centrifugation. Centrifuges are used to further study biochemistry and separate large quantities of substances. For example, cells are collected, plasma is isolated, DNA and protein molecules are isolated from these pre-purified preparations, and viruses as well as large-scale E. coli, strict cell components, nucleoprotein particles, etc. can be isolated. This machine adopts brushless motor, microcomputer control, with automatic calculation and setting of RCF. It has the advantages of multiple program protection, easy operation and maintenance-free.

II. Working principle

The centrifuge uses the principle of centrifugal sedimentation to separate, concentrate or purify cells (particles) with different densities in the solution under the action of centrifugal force.

Place the centrifuge tube containing the same amount of test solution symmetrically in the test tube hole of the rotor. After starting the instrument, the relative centrifugal force (RCF) generated by the motor driving the rotor to rotate at a high speed separates cells (particles) with different densities in the test solution. The size depends on the horizontal distance from the position of the sample to the axis, that is, the rotation radius r and the rotational speed n, and its calculation formula is as follows:


n ------------Speed (r/min)

  r -----------Rotation radius (cm)
