Liquid nitrogen diffuser

thingiverse

Here I designed a nitrogen diffuser to draw off liquid nitrogen (or any other liquid) coming from an high pressure source. I tried it to draw off Liq. N2 from 70L dewar (about 1bar pressure) into a small narrow dewar for cooling trap, and it works. Still not tested how many cooling cycles it can withstand. I will try it to draw off from high pressure liq.N2 tank (7bar pressure), then I will let you know. Works also with water, to slow tap water coming from laboratory taps. Obviously, liquid nitrogen MUST BE handle only by trained persons. Use it at your own risk. https://youtu.be/QRvEGYDn8k4
