AI Technical Summary

Technical Problem

In existing centrifuge devices for separating mesenchymal stem cells, the test tubes are not fixed stably and tend to tilt, resulting in insecure fixation.

Method used

The device employs a combination of a fixed mechanism, fixed components, a fixed disk, a rotating disk, a clamping rod, a first gear, a mechanism seat, a gear ring, and a second gear. By rotating the gear ring, multiple rotating disks are driven to rotate synchronously, thereby achieving multi-directional clamping of the test tube and ensuring that the test tube is vertically fixed.

Benefits of technology

This method achieves stable fixation of the test tubes, prevents them from tilting, and improves the reliability and safety of the experiment.
