What do you use 100ml droppers for? We have some here that are brand new. They don't fit in the unitrays. Do any of you use them for anything? Do you use them in the unitrays without the divider? or is there a different storage tray that's convenient for a set of 10? I was thinking universal indicator would be good in them but I'm not sure how to keep them conveniently on the shelf...

Can you buy caps for them? You could save them for prac exams where they need <100mL of solution per student. If you want to use them for dropper bottles, could you get your TAS people to drill holes in a block of wood to fit the bottles?

you can get the solid caps from Science Supply.

I still use them, I use a sturdy food storage container to store 6 x. I print labels off riskassess for the bottles and the container. I prefer the 50ml, the rubber teat/droppers do perish though. I get mine at the end of the year usually with budget remainder, or to flesh out an order. You can just use a rubber stopper depending on the solution, handy for indicators you only need a little bit of.

I tend to tore our chemicals with the sealed caps and only swap over to the rubber droppers for use in class. Got sick of all the droppers perishing.
