Do you Refrigerate/Freeze your lyophilized powder?

[steppinthrax]

Simple question,

My quess it it shouldn't matter since it comes in the mail the whole way with no special refigeration.

Seems like there could be some logical fallacies associated with your postulation. Try your argument with milk.

The warmer it is, the quicker it will break down. It won't become poisonous but it will become less effective over time. There is no way to stop that, but freezer temperatures slow it.

Freezing at -80C. My stash should be good longer than my lifetime.

at -80 you must be using a ultra low temp freezer. I see them online go for 2 - 4K, of course you have used med equipment from Marketplace. Walmart sells a ultra low fridge that's advertised as going -40 for around 300 bucks but I'm not sure if I trust that.

It's a used vaccine freezer off Ebay

The shipping time is quite short compared to the relative time one would want to store peptides.

Ali express sells the same freezer for 215 free shipping from US. I just bought one.

What is the refrigerant in Chinese copy? Trying to understand how close is it to the original. The control panels are different, but I don't think that itself is an issue

Looks same but in red. Looks like a rebranded version.

That looks like the exact same fridge I saw from Walmart, even the display in the corner is in the same place and same style but the whole thing was in Black

R290 aka propane.

Ok, that's different from ULT25NEU, which is R-170 (Ethane). So Chinese version looks similar externally, but different hardware design.

The Alibaba freezer above (the red one) only gets down to -40 but does it reliably. I am pretty happy with it overall. I think the ULT25 is -86c but much smaller and much more expensive.
