Can anyone recommend a dropper bottle?

Can you help when choosing? I need it to accurately measure when I'm doing droppers in my eyes. I don't want any plastic crap. It needs to be all glass with metal, and it needs to be a dropper. I have a few other drugs I'm dropping in my eyes and so they need to be separate. I've been using a plastic one but I don't think that's a good idea so I'm looking for an upgrade. What's your favorite dropper bottle that is all glass with a metal dropper? I want to be able to dropper it accurately and keep it clean and be really easy to dropper. <br><br>TL;DR: What dropper bottle do you recommend that is all glass with a metal dropper?
