Selected User Reviews For 12PK Watch Glasses, 5" (12.5cm) - Cover Lids for Beakers & Flasks - Evaporation Dish - Polished with Ground Edges - Eisco Labs

Covers are of good quality, have smooth edges, and are clear

5/5

It's not borosilicate glass, but it could be flint glass. I ordered some large ones, and they appear to be quite thin in comparison to the heat resistant ones I've used previously - That is why I believe they are made of flint glass. I use these to cover beakers, sometimes at low temperatures but never at high temperatures, so they're perfect for me. They're also what I use with my microscope. I'll probably get a few smaller ones as well - I'll let you know as soon as I've double-checked that these are working properly.

Good product at a good price; I used one to replace the glass in my barometer and now have extras!

They appear to be of good quality, but you don't have any

4/5

They appear to be of reasonable quality, and you won't require much else. Everything is in good working order, including the glass, which is clear and has an even cut.
