The type of centrifuge rotor is introduced

Fixed Angle rotor refers to a fixed Angle between the central shaft of the centrifugal tube and the rotating shaft, most of which is between 14 and 45 degrees. The larger the Angle, the better the separation effect. The advantages of this rotary head are low center of gravity, balanced operation, and can quickly collect sediment. However, when the particles settle, they will hit the centrifugal tube along the centrifugal force direction, and then slide along the tube wall to the bottom of the tube, forming precipitation. The wall effect is easy to cause strong convection in the tube, affecting the separation effect.
There are two types of common centrifugal rotors: fixed Angle rotors and horizontal rotors. Here are the main differences:
Fixed Angle rotor:
Fixed Angle rotor refers to a fixed Angle between the central shaft of the centrifugal tube and the rotating shaft, most of which is between 14 and 45 degrees. The larger the Angle, the better the separation effect. The advantages of this rotary head are low center of gravity, balanced operation, and can quickly collect sediment. However, when the particles settle, they will hit the centrifugal tube along the centrifugal force direction, and then slide along the tube wall to the bottom of the tube, forming precipitation. The wall effect is easy to cause strong convection in the tube, affecting the separation effect.
Horizontal rotor
Also known as the swing rotor, consisting of a horizontal rotor, a hanging basket and an adapter. When stationary, the basket is in a vertical state, while when running, it is in a horizontal state, at a right Angle to the bearing. The sample will concentrate precipitation at the bottom of the centrifugal tube. The advantage is that the position of components in the sample relative to the tube wall does not change during and after centrifugation, so the centrifugation effect is better than that of angular rotor.

Daily maintenance and calibration of pipette
a. After each experiment, the scale of the pipette gun should be adjusted to the maximum so that the spring can return to the prototype to extend the service life of the pipette gun. b. Pipettes with liquid suction should not be placed flat: the liquid in the head can easily contaminate the inside of the gun and may cause the spring of the gun to rust. c. When setting the range, please be careful to rotate until the required range number is clear in the display window, and the range set is within the range of the pipette. Be careful not to rotate the button out of the range, otherwise it will jam the mechanical device and damage the pipette.
