This equipment is particularly suitable for the rapid separation and synthesis of trace samples. The speed of a high-speed centrifuge is usually between 10,000 and 30,000 r / min, and the speed exceeding 15,000 r / min is called an ultra-high-speed centrifuge. This type of centrifuge is mainly used to separate, prepare and analyze biological samples, such as cells, tissues, proteins, nucleic acids, etc.

A plurality of slide bars 11 are fixedly installed on the upper end surface of the turntable 6 through a plurality of mounting grooves. Two slide blocks 13 are slidably installed on the outer wall of each slide bar 11 through a limiting mechanism. The limiting mechanism includes limit rods 12 fixedly installed on the inner walls of the plurality of mounting grooves. Each limit rod 12 slides through the two slide blocks 13. The limit rod 12 can limit the two slide blocks 13 so that the slide blocks 13 can only move axially along the outer wall of the slide bar 11. A telescopic spring 14 is installed on the outer wall of each slide bar 11, and the two ends of the telescopic spring 14 are elastically connected to the inner walls of the two slide blocks 13 respectively.
[0023] The outer walls of the two sliders 13 are fixedly installed with clamping blocks 16 through a connecting mechanism. The connecting mechanism includes a connecting rod 15 that is fixedly installed on the outer wall of the slider 13. The end of the connecting rod 15 is fixedly connected to the outer wall of the clamping block 16. The two clamping blocks 16 are fixedly installed with anti-slip pads 17 inside. The shell 1 is rotatably installed with a rotating rod 19 through a connecting mechanism. The connecting mechanism includes two connecting plates 18 that are fixedly installed on the outer wall of the shell 1. The rotating rod 19 is rotatably installed between the two connecting plates 18. The outer wall of the rotating rod 19 is fixedly installed with a connecting block 20.
