Tips:
1. Beakers are generally not used as measuring instruments.
2. Before heating the beaker, wipe the water from the outside of the beaker.
3. We recommend that liquids heated in beakers should not exceed 2/3 of the beaker volume.
4. When heating corrosive liquids, in order to avoid liquid splashing on the skin, we recommend the use of watch glass cover.
5. In order to prevent the beaker from breaking during the mixing process, the glass rod should not touch the bottom or wall of the beaker when dissolving materials with the glass rod.
6. The margin of error is ±5%

These feel like very durable glass measuring cups for liquids. It's easy to read the measurements and they nest perfectly within each other not taking up very much space.

These beakers are great, love the sizes and they work. The main thing that caught my attention was how well packaged they were. The Amazon driver could have thrown these from the driveway and I don’t think they’d have broke. I’ll be ordering again

these are great. only got 4 stars because one of the six came broken so of course I could not use. with that said they are very durable for being glass beakers. they are perfect for when i make my lotions and hand creams because they with stand the heat really well and a stir bar. I am sometimes not so graceful and have dropped them from time to time and they are holding up really well. No cracks or scratches i can see and have been using them frequently since purchase. The 250ml size is perfect for about 90% of the things I make and i love they were very affordable

I mean, they’re beakers, what else could you want to know? I haven’t broken them yet, and I break EVERYTHING, so that speaks well of them

Good beaker except for the gradations, which read about 50ml lower than actual volume. I compared with a US made vessel and also weighed. US vessel and scale matched, Okûlab beakers marked gradations are at accurate intervals, but the whole scale is printed too high on the side, 50ml too high.

The bottom is not flat, and it wobbles when sitting on a flat surface.It still works well and for the price is hard to beat.

the 1000 ml beaker had a chip. i shouldn't have to buy 2 sets to get a full set. too much bother to return inferior Chinese products .

Only 900 ML is graduated. The rest you have to guess. No idea where they got the picture they're using.
