My massive stash is in my even-more-massive chest freezer. Stuff I'm likely to need to get at in the next year is on a shelf near the top, stuff I won't need for years is at the bottom.
I got a NIIMbot on prime day. I'm obsessed with it and am labelling things all over the place.
I never labelled my individual vials. I bought three kits at a time, packed them into thermoses that hold thirty vials, labelled the outside and inside the lid of the thermoses, and chucked them in the freezer. When I couldn't fill a thermos with the same batch, I packed in things with different colored caps, and labelled what color cap meant which thing.
I want to label my individual vials. It would be so cool that, any time I pulled a vial, it said what it was, what it came from, the amount in it, the batch number, and when I got it. I can do that with any kits I have coming; but I have a decade's worth of stuff in the freezer and I want to do it.
But those are packed into thermoses that have never been opened, dessicant packs on top. For every set of vials, it will mean opening it, dumping out the vials, putting the labels on, repacking them into the thermos dessicant back on top, and close it up. I'm guessing that'll take 5-10 minutes each, during which time they will warm up and then refreeze.
I think this is absolutely fine and I am being silly. I ALSO simultaneously think this is going to be putting them through a freeze-thaw cycle and I'll lose potency for no good reason except that I wanted to label things after the fact.
Somebody tell me it's fine, calm down. Or tell me it's NOT fine, don't do it, everything will be ruined forever.
