What To Use Loading Liquid Nitrogen

Edit: Henan Tianchi Instrument Equipment Co., Ltd    Date:2018-04-23
What to use Loading liquid nitrogen? I don't want to spend a few hundred dollars to rent a cylinder. Also, I bought liquid nitrogen to buy high-purity nitrogen is not a bit wasteful ... high-purity nitrogen or liquid nitrogen cylinders with fire extinguishers so big? Can the stainless steel insulation cup contain liquid nitrogen? It is said that someone used a thermos bottle and the liner exploded when it fell. How do you do it?
Stainless steel insulation cup is actually possible, but can not hold much liquid nitrogen, it is estimated that will not run for long to run light, large liquid nitrogen bottle is made of stainless steel, but also can withstand a lot of pressure, insulation cup can not be pressure but can be insulated . What we used to be very large in the past was the use of liquid nitrogen in many general warm water bottles. Of course it is best to use a liquid nitrogen tank, which is vacuum insulated.
What To Use Loading Liquid Nitrogen
The tank containing liquid nitrogen is called a liquid nitrogen tank. It is made of aviation aluminum alloy. The glass in the thermos bottle will surely burst. Do not use liquid nitrogen tanks, you can also use Dewar flasks. Smaller amount can choose insulation cup, cylinder type can be. Easy to operate and saves liquid nitrogen. It was often used before sealing the polymerization. There was no danger. However, it must not be sealed and must be open to the atmosphere. Too much pressure will also explode. Sealed, the volume expansion of liquid nitrogen vaporization is not a bomb? Open your mouth or cover it with a cover so that the gas can run out.
