dewars

Then I get a bottle of 12 year aged Dewars for $35 and my god was the Dewars better...

But they don't take into account that: 1) Vacuum flasks / dewars use a vacuum for thermal insulation.

I think the one at the local university takes several dewars of helium just to bring it online.

The original vacuum flasks were made of glass, and a lot of laboratory grade vacuum flasks and Dewars are still made of glass.

Maintaining a building, as well as receiving a weekly delivery of liquid nitrogen and topping up a few dozen giant dewars and monitoring their temperatures.

Next time, I switched what was in the bottles, it was the Dewars that won.

Some dewars have a better or worse vacuum than others.

I wouldn't be surprised if Goldman Sachs had warehouses full of dewars of helium...

Patients can be transferred between dewars if necessary.

Iv been trying to keep an eye out for used LN2 tanks and dewars on different used places so I can grab one for cheap.

Readers that half understand vacuum flasks / dewars: no or fewer gas particles in a vacuum means no or less energy those particles can collectively transport, that is correct but ignores the measures taken to prevent radiative heat loss.

The dewars I was talking about above hold several hundred liters, are about 5-8 feet tall, and primarily for liquid helium (where evaporation is way more of a factor.

There was some discussion in Dewars book "To the End of the Solar System"[1] about the different cultures at the national labs related to the development of nuclear thermal rockets.

The non-pressurized LN dewars I've seen had a "plug" that was just a cylinder of foam that slid into the neck of the dewar, with a light plastic cap on top.

One of the wealthiest men I have ever met co-founded what is now "The Nation's Largest Sperm Bank" with a $2,500.00 investment, mostly to buy medical and lab equipment, like liquid nitrogen dewars.

One of the very wealthiest people I have ever met founded "The Nation's Largest Sperm Bank" in the early 1970s with $2,500.00 of his own money, along with just one other partner, mostly for liquid nitrogen dewars, medical lab equipment as well as pr0n.

Avoid the lower tiers of the big blends (Johnny Walker, Dewars, etc) - they are mostly grain alcohol.
