3.1 Medical centrifuge medicalcentrifuge It is widely used in the fields of medicine, biology and pharmacology, which can stabilize the speed around the rotary axis at different angular speeds. Rotating calibration or test equipment. 3.2 Full load ful-load Operation of a medical centrifuge at maximum load. 3.3 No-load no-load Operation of a medical centrifuge under no-load conditions.

4 Overview

Medical centrifuges use the centrifugal force of rotating motion and the difference in buoyancy density to separate, concentrate and purify raw materials. Equipment for each component in the sample. It usually consists of a rotating device, a speed control system, a centrifugal chamber, a centrifugal turntable and a base. It is widely used in related laboratories such as medicine, biology and pharmacology, as well as blood stations, physical examination centers, hospitals and other medical institutions. in medical institutions. There are many types of medical centrifuges, and there are many classification methods. according to the structure, they can be divided into desktop medical centrifuges and vertical centrifuges. Medical centrifuges (also known as floor-standing medical centrifuges); can be divided into refrigerated medical centrifuges according to whether there is a temperature control system (also known as low-temperature medical centrifuge) and normal temperature medical centrifuge; according to the centrifugation method can be divided into preparative medical centrifuge and centrifuge Analytical medical centrifuges; according to the speed can be divided into low-speed medical centrifuges, high-speed medical centrifuges and ultra-speed medical centrifuges machine, see Table 1. ......
