AI Technical Summary

Technical Problem

Existing centrifugation equipment is prone to causing precipitated particles to become suspended in the supernatant during operation, affecting the clarity and purity of the supernatant, and consequently impacting the accuracy of experimental results and the stability of product quality.

Method used

A centrifugal separation device for supernatant that prevents sedimentation was designed. The device achieves minute up-and-down reciprocating motion through the cooperation of the guide cylinder and the ball bearings. Combined with the high-speed rotation of the motor-driven shaft and the placement rack, a strong centrifugal force is generated to prevent sediment from accumulating. At the same time, the structure of the sealing cover, the clamping rod and the spring ensures the safety and reliability of the equipment.

Benefits of technology

It effectively prevents precipitates from accumulating at the bottom of the separation tube, maintains sample homogeneity, ensures the clarity and purity of the supernatant, improves the safety and stability of the experiment, and avoids liquid leakage and equipment damage.
