It is not easy to tip over on the workbench, making it safe when handling liquid nitrogen.
The glass outer wall does not condense moisture.
No glass cracking occurred, which shows that the material quality is very good.
In the laboratory, I use it to store liquid nitrogen, and the 350 ml small capacity is just suitable for experiments.
I have used it for more than half a year without cracks. The silver-plated glass surface reflects well, and the insulation effect is stable.
