It isn’t, but as Thetimefarm above says, the paper trail is what matters. Medical grade liquid helium for MRI machines is a thing. That paper trail is what adds a few zeros to the cost.
As a side note, this is similar to why Fluke multimeters are so expensive:
tl;dw: companies have reams of documents for their certification procedures of equipment, and calibration of the equipment to certify the equipment, and they’re based around the specifics of Fluke mutimeters. They aren’t more accurate or even much fancier than a nice hobbyist meter. Those companies must buy Fluke or completely redo all their procedures with accompanying documentation and certifying by professional engineers. If you’re not such a company, don’t bother spending all that extra money on Fluke.
Yeah, it’s weird. Like yes, all these people put in a lot of effort to make sure that when people could die from equipment failure, we make sure that equipment is very, very good. Adding zeros to the price is the cost of that.
I presume that it has to be certified and probably heavily filtered. It’s not going to be the same as what goes into party balloons.
Liquid helium is -269 °C. There is no risk of confusing it with what’s in balloons.
And its a medical setting which means that the products you use will be certified and calibrated in just the right way.
There isn’t much difference at all.

Amazingly people hate this concept, and it’s strange. We all got downvoted for pointing this out.
