5 Pack Glass Graduated Measuring Beaker Set 5ml 10ml 25ml 50ml 100ml Thick Glass Borosilicate Low Form Lab Beakers

I ordered these beakers to use for mixing essential oils. I love them! However, be warned that they are made of VERY thin glass. One of my cats knocked over a couple from my first set, and they broke. I ordered a new set, and one beaker was broken when I received it (even thought the box looked fine and the beakers appeared to be packed well). I was able to exchange for a replacement set, no questions asked, and it was super easy and quick! I don't heat them up, so I can't speak to their heat resistance.

Understand these are very small beakers but I knew that before ordering, The 2 smallest ones can be used to hold other small items upright that would otherwise fall over (spilling contents, etc.). None received broken. I finally have enough beakers for my needs.

The one that I would use most often (250 ml) was shattered. They were packaged well, one inside the other. I didn't inspect each one when they arrived. It had t have been broken before it shipped to me. All the others were fine. I didn't realize I had a broken one until it was too late to return them.As far as accuracy is concerned, they say they are approximate.Glass is thin.

Arrived on time and they are just what I needed for my project. I really like the different sizes.

The glass is thin and one piece was broken inside the middle of the stack when I unboxed them, but it was a couple months ago when I bought them so I can’t return it just beware

My first order arrived with a broken 50mL beaker. It’s in the middle of the package (they arrive nested in each other) but was the only one broken. I arranged for return which is a hassle because I have to go to staples to do it. The replacement came. Same one is broken. the box looks fine. I’m guessing this is a factory QC issue. I need to now set up an annoying return again.

The small size of these beakers are perfect for minimizing the amount of solvent or other chemicals used for soaking small parts in during cleaning. I don't have to worry about the borosilicate glass resisting any of the solvents used, like I did with small plastic or metal containers. These are very small, and very thin glass at this size, so some extra caution is required to not break them. They do all nest one inside of the other for storage, but not snugly, so if you're going to transport them like that as well, you'll need to add a sheet of paper or other packing material pushed in between each one to prevent them from rattling and possibly cracking each other.

My daughter is taking an online college chemistry class. One day she accidentally broke one of her glass measuring beakers. She needed a new one in just a few days. Thankfully, this set was available for quick shipping. It was such a relief to be able to quickly replace the beaker in time for her next deadline. My daughter stated that it works fine!
