Liquid helium is the most unique component in its properties. Takes the second place in the table of chemicals.
But the main first place in the group of inert gases. It is very light, has no taste, comes in three states of aggregation.
At the same time, liquid helium is the coldest liquid on planet Earth (the temperature is 0 degrees and it is still liquid).
It has superfluidity, the density is 0.00018 g / cm 3.
The boiling point of liquid helium is 269 degrees, and the melting point is 272 degrees.
Used for MRI. As a refrigerant for super low temperature research. In the nuclear field, as a coolant for a certain type of reactor. For repair work, for leak detection and piping systems.
As a filler in the LED industry, for filling lamp bulbs, as a heat wave removal.
In mixtures for cylinders (for diving divers).
To buy liquid helium in bulk - put the company details in a letter to firstname.lastname@example.org
Indicate the volume of the purchased product (number of liters: 10l, 20l, 50l, 100l).
The price of liquid helium varies from the volume purchased and can be reduced by purchasing additional items. Therefore, first familiarize yourself with the products presented on the company's website.
Storage is carried out in a warehouse - in specialized cylinders or in Dewar vessels.
