AI Technical Summary

Technical Problem

During the transportation of liquid nitrogen tanks, they are prone to tipping over, overturning, and collisions, which can shorten their service life and increase safety risks. Furthermore, violent shaking can exacerbate the evaporation of liquid nitrogen, affecting the freezing effect of sample collection.

Method used

A device comprising a protective box and a transfer mechanism was designed. Through components such as protective plates, elastic elements, magnetic supports, and the transfer mechanism, the liquid nitrogen tank is secured and protected in all directions to prevent tipping and impact.

Benefits of technology

Effective protection of the safety and integrity of liquid nitrogen tanks during transportation, reduction of liquid nitrogen evaporation, ensuring timely sample freezing, and minimizing the impact of stress on genome sequencing results.
