Characteristics and differences of horizontal and angular rotors in centrifuges At present, the rotors commonly used in laboratory centrifuges are horizontal rotors and angular rotors. How do you choose to use them? The horizontal rotor allows for large volume separation and facilitates delamination from the centrifuge tube. However, the horizontal rotor has a higher center of gravity and a higher resistance. It is not suitable for high speed separation and has a small amount of wall effect. Second, the centrifugal angle rotor structure features: the center line of the centrifuge tube in the angular rotor and the rotating shaft at a fixed angle of 20 ~ 40 degrees, the greater the angle, the better the separation effect. The angle rotor can achieve low center of gravity, low resistance, stable operation, and high speed separation. However, it is not suitable for large-capacity separation. When the particles are settled, they first collide with the centrifugal tube in the direction of centrifugal force, and then slide along the tube wall to the bottom of the tube. Particles will be deposited on one side of the tube to cause wall effect, which will affect the separation effect.

Here is a detailed description of the characteristics and differences between the two rotors:
First, the working characteristics of the horizontal rotor of the centrifuge:
1. When the horizontal rotor is stationary, the center line of the centrifuge tube in the rotor is parallel to the rotation axis.
2. When the horizontal rotor rotates and accelerates, the center line of the centrifuge tube gradually transitions from a parallel position to a position close to the rotation axis.
3. When the horizontal rotor is decelerating, the center line of the centrifuge tube gradually becomes parallel to the position perpendicular to the rotation axis.
