Hi have half an A4 copy paper box full of these with no lids. Any suggestions for use? They haven’t been used in the nearly three years I’ve been here. If they’ve got a good use I’m happy to look at getting lids for them rather than disposing of them. My only thought so far is the rusty nail prac but we just use test tubes for that…

Just a thought - is the top the same size as a dropper bottle? You can buy caps for the dropper bottles.

Use a stopper. I have a stack of lids that seem to fit lots of little bottles. Don't know where they came from though. I use little bottles for powder testing, keep them in kits.
