Technical Field

The utility model belongs to the technical field of centrifugal equipment, concretely relates to laboratory centrifuge.

Background

When a suspension containing fine particles is left to stand still, the suspended particles gradually sink due to the action of the gravitational field. The heavier the particles, the faster they sink, whereas particles of lower density than the liquid will float up. The speed at which the particles move under the gravitational field is related to the size, morphology and density of the particles, and in turn to the strength of the gravitational field and the viscosity of the liquid.

The centrifugation is to accelerate the sedimentation velocity of particles in liquid by using a strong centrifugal force generated by the high-speed rotation of a centrifuge rotor, and separate substances with different sedimentation coefficients and buoyancy densities in a sample.

During the centrifugal rotation, the rotation angle of the test tube needs to be adjusted, so that the particles in the liquid can be settled to the bottom of the test tube. Therefore, the utility model provides a laboratory centrifuge; the upper and lower positions of the test tube are limited by the cover body, and the phenomenon that the particles are too high to be accurately separated from the liquid due to too high sedimentation positions is avoided; the test tube can be taken out through the cover body in an integrated manner without being pulled out manually and independently; and a rotator structure for regulating and controlling the rotation offset angle of the test tube.
