I use them for ants so haven’t tested them for heat shock but they’re great for visibility. Gonna buy again.

Plain glass tubes… no writing or labels. Strong and well made. The box has cardboard dividers which makes storage easy.

I got these so I can turn them into meth pipes and then sell them to my meth head friends cuz that's what meth friends do LOL just kidding people actually got them to store spices in on the range of the marijuana spices LOL not kidding on that I did have to take the corks though that came with them and cut little kind of grooves into them so that the they would hold them into the glass tube better so otherwise it just kind of slip and fall out but the packaging is great on it none of them broken or anything like that you know maybe a couple of little scratched you know on the lines of almost having a crack but not so I've been happy there and then we're broken out but other than that I'm happy

I am one of those whom actualy use test tubes to conduct tests.These tubes have a failure rate above 40%when heating a sample.I can hear it already. "You don't just put them in an intense heat source."I don't. I have tried slowly heating the tubes. You know warmming them up. The tubes still crack. I have had to anneal these tubes in order to get any use from them.No I shall not recommend these low vrade tubes.
