EDUPET THEMONG 11pcs Plastic Graduated Cylinders and Beakers Set, 10ml, 25ml, 50ml, 100ml, 250ml Cylinders with 25ml, 50ml, 100ml, 250ml, 500ml, 1000ml Beakers and 2 Brushes, Ideal for Science Lab

This set was low-cost and I received it promptly after ordering. Let me make this clear: I did NOT purchase this set because I needed legit laboratory equipment. I bought it because I needed a few of the smaller size beakers to measure refrigerant oil for air conditioning systems used in automobiles. I needed these to measure amounts between 50 ml to about 200 ml with accuracy that was better than an old kitchen measuring cup. My other requirement is that they hold up reasonably well to strong chemical solvents such as brake cleaning fluid. This set has done both of those things. The plastic has withstood contact with refrigerant oil and brake clean very well. As an aside, I also like that all pieces have raised molded markings in addition to printed ink markings. This was also a concern of mine, considering their intended use. Most chemical solvents take ink off of plastic very rapidly. If you are looking for a reasonably priced set of measuring vessels that are not going to have to withstand the rigors of a true laboratory, this is it. I would recommend these especially to anyone who wanted a Mad Scientist Playset for the kids; you can't beat the price, they actually measure liquid, they seem at least as durable as any toy plastic can be, and they included two bottle brushes to help with cleaning. :-) I hope this helps in your purchase decision.

I can't attest to how accurate these are - but if you want to have fun with science, these are great. We fill them with water, or other liquids and pour and pour! Back and forth! Yes, they were bought for a child and they have provided hours of fun. The bottom of one cylinder was stepped on and broke slightly, but the rest held up quite while! Well worth the purchase price!

I am using these to mix dyes and these give me way more accuracy than a measuring cup or something. I will say that one of the small cylinders (25ml) was cracked and leaks, but the item was packaged well and I don't think it was broken in shipping. I suspect it was damaged at the warehouse in storage. All in all, this set meets my needs and is a good value, so I cam keeping them.

Basic measuring devices , very tough material not easily broken , not to difficult to read . The 250 ml graduated cylinder accuracy stated at +or - 2.5 ml at 20 c . The 100 ml graduated cylinder rated at +or - 1 ml at 20 c . The beakers are very nice and graduated with pouring spouts , should stand up to painting solvents , dense plastic . Very satisfied at this price point.

This is what it is! My daughter likes using these to measure with. She has made color mixing experiments, chemical reaction experiments, measuring calculations, measuring for homework, etc. the list goes on for how useful these are. They are thick plastic very durable. I would recommend this to everyone.

Cheap, but effective. I got this set because I needed to match paints/stains on a few pieces of furniture I repaired. Once a match was made, I could accurately mix a larger amount for painting or staining the furniture.As a retired chemist, I almost bought glass (old habits die hard!), but figured I couldn’t break these plastic ones. I was right; knocked several beakers with elbow and to the floor they went. Beakers-1 Gravity-0

The only think I disliked is that it’s not very easy to read when using in a class full of third-graders. I used a marker to go over the lines and numbers. But I love that they come in different sizes and come with the brushes to clean them. They’re easy to use and there were plenty.

i was getting dodgy results with these graduates and decided to check them on a scale. The 1 liter graduate was off more than 5%. I tared the graduate and slowly filled it with pure water until I got 1 kg. The cylinder was full well above the 1000mL level. These graduates do have a place if you're clumsy and drop things, but do check the graduation markings using a scale and water. I've had to put new markers on mine.
