AI Technical Summary

Technical Problem

Existing cuvettes are incompatible with centrifuge tubes, making them prone to displacement or breakage during centrifugation. Furthermore, the lack of an effective sealing structure affects the accuracy and safety of experimental results.

Method used

A cuvette for centrifugation was designed. By setting an elastic gasket and a sealing groove inside the centrifuge tube, combined with a sealing cap and a connecting seat, the cuvette is ensured to be stably fixed during centrifugation. The sealing groove and raised strip enhance the sealing performance and prevent sample leakage.

Benefits of technology

This method achieves stable fixation and sealing of cuvettes during centrifugation, preventing displacement or breakage, improving experimental accuracy and efficiency, and reducing sample transfer steps.
