About the Rotor Introduction of Automatic Capping Centrifuge

 

 

The automatic cap removal centrifuge is a kind of conventional laboratory centrifuge machine that automatically removes the cap of the vacuum blood collection tube during the centrifugation process. It is widely used in clinical medicine to remove the cap of the vacuum blood collection tube, thereby improving work efficiency.

 

When using an automatic capping centrifuge, it should be noted that the centrifuge tube is subjected to the action of a strong centrifugal field, and soft centrifuge tubes (such as polypropylene) will collapse if the tube is not filled with liquid. When the particles settle in the angle rotor, they first hit the tube wall in the direction of centrifugal force, and then slide along the tube wall to the bottom of the tube. As a result, particle deposition occurs on one side of the test tube, a phenomenon known as the wall effect. The wall effect is easy to cause the convective disturbance of the settled particles by the sudden change of speed. If the inner surface of the tube is rough, particle movement is hindered, and sometimes particles stick to the tube wall to form small lumps.

 

The rotors of automatic capping centrifuges are commonly divided into angle rotors and horizontal rotors.

 

  • What is an angle rotor.

The angle rotor is the abbreviation of fixed angle rotor. The angle θ between the centrifuge tube filled with the solution and the centrifuge shaft is formed when the centrifuge rotor is manufactured, and the angle cannot be changed. The angle between the two is generally between 14°and 45°. During the centrifugation process, the position of the centrifuge tube is fixed and the sample is redirected. The smaller the angle between the centrifuge tube and the rotating shaft, the greater the degree of redirection. The higher the efficiency.

 

  • What is the horizontal rotor.

The horizontal rotor is also called the swinging rotor. The centrifuge tube is placed in the hanging cup. The hanging cup and the rotating shaft are in vertical and parallel state when they are stationary. The hanging cup must be symmetrically hung on the rotor when in use. When rotating, the hanging cup is thrown from the vertical position to the horizontal position by centrifugal force, so it is also called the outer swing rotor and the leveling hanging cup rotor.
