AI Technical Summary

Technical Problem

In nuclear magnetic resonance spectrometers, the plastic hose connecting the liquid nitrogen tank to the spectrometer magnet is prone to freezing, cracking, and shaking, leading to the risk of liquid nitrogen leakage, which affects the smooth addition of liquid nitrogen and the safety of the equipment.

Method used

A liquid nitrogen auxiliary device for nuclear magnetic resonance spectrometer was designed, including a support assembly, a connection end fixing assembly, a hose support assembly, and a support leg assembly. By supporting and fixing the hose, shaking and displacement are reduced, thereby improving stability and safety.

Benefits of technology

It effectively prevents the hose from freezing and cracking and shaking, ensuring a stable delivery of liquid nitrogen, improving experimental efficiency and safety, and adapting to the liquid nitrogen filling needs of liquid nitrogen tanks of different sizes and locations.
