Description

Desk-top high-speed centrifuge Technical Field The utility model belongs to the technical field of centrifuges, and particularly relates to a desk type high-speed centrifuge. Background The high-speed centrifuge is laboratory equipment, and is widely applied to the scientific research and production fields of biology, chemistry, medicine, agriculture and the like, and is used for separating, extracting and concentrating various components in a sample. The working principle is based on centrifugal force generated by high-speed rotation, so that particles in suspension or mixture are settled, and the separation effect is realized. The patent with the prior application number of CN201920276418.3 discloses a desk type high-speed centrifugal machine, which comprises a shell, a top cover, a control panel, a power supply, a centrifugal chamber, a driving device and a cooling device, wherein a purple light lamp electrically connected with the control panel is arranged on the inner side of the top of the shell, the cooling device comprises pressure equipment, speed regulating equipment and a spiral condensing pipe which is matched with the outer wall of the centrifugal chamber, the water tank is arranged on the outer side of the shell, the spiral condensing pipe is fixed in the shell by an I-shaped screw, a water inlet of the condensing pipe is communicated with a water outlet of the water tank and a water inlet of the water tank respectively through pipelines, the pressure equipment is connected with the speed regulating equipment, and a pipeline through hole and a temperature sensor electrically connected with the control panel are arranged on the right side of the shell. However, the technical proposal has the problems that the device has no door locking structure, the centrifuge can be injured by workers when the centrifuge is not stopped, the device can not detect the rotating speed of the centrifuge, and the centrifugal rotor can fly out to cause personnel injury once the centrifugal rotor is balanced when the rotating speed of the centrifuge is too high. Accordingly, a tabletop high-speed centrifuge has been proposed to solve the above-described problems. Disclosure of utility model The utility model provides a desk type high-speed centrifugal machine, which solves the problem that the centrifugal machine in the related art cannot detect the rotation speed of the centrifugal machine and the balance of a centrifugal rotor.
