Dewar Ditty


#1

Dewar ditty, I’m a wondering what to do.
Dewar ditty, liquid N or CO2?

Dewar ditty, got to chill some ethanol
Dewar ditty, without going in the hole.

Dewar ditty, I’m still wondering want do
Dewar ditty, so I’ll ask the Good Life crew…


There are a number of threads discussing how to get your solvent cold.

Either on a budget, or in a hurry, or with huge chillers that aren’t a huge disappointment.

I needed to get that ditty out of my head, and I’m gonna try direct liq CO2 injection.

I figured I’d try and document where the required clues can be found lying around, while I go find them again.

Under the assumption that that would be useful for others later.

Getting two birds stoned is almost always a win :wink:

A client suggested these as a solution, https://c1d1labs.org/low-temp-and-explosion-proof-freezers/

I responded with “how about we get a CO2 Dewar, and see what we can manage…”.

Chances are he’ll do both.
