50ml Beaker, Low Form Griffin, Borosilicate 3.3 Glass, Double Scale, Graduated, Karter Scientific 213D31 (Single)

I was very impressed with these, they were perfect, crystal clear, bubble free, and they arrived in perfect condition. They were packaged carefully and padded so they did not have any damage upon arrival. The size and fit are accurate, the glass was thick and great quality, I feel like these will last a very long time!

Out of all of my Amazon orders this one unlike many of the others is exactly as advertised. Great job! Maybe Amazon and their affiliates will learn from your professional business model. That is all!

Very beautiful glassware! The dimensions stated on the produce page were accurate. You can’t beat this for the price! Glass is thick, and doesn’t feel super fragile, which is always a concern of mine when buying lab glass. I haven’t tested it with extreme temperatures, so you may want to check other reviews for that (I only need this for room temp collection, and measurements) The writing on the glass is very big, and clear! I don’t need to strain my eyes to see it, even with dim lighting. I took some liquid measurements and they seemed to be accurate enough. I didn’t notice any glaring inaccuracies. So all of my concerns have been put to rest. The only regret I have is that I didn’t buy the 6 piece set for $4 more. I didn’t see that deal until after I placed my order. I will definitely be returning for more in the near future.

10/10. Easy to use, accurate as described, perfect thickness for chemical retention. Bubble feee and very sturdy. Would buy again.

I bought this 6-pack beaker set for general household use, and they're certainly good for that. They come well-packaged, arrived undamaged (I was worried about that), and the glass and the graduations are in perfect condition. Despite what the product info may imply, they're made in China. Unpacking was a bit difficult, and finding a good way to store the set is also not the easiest. I ended up trimming the original packaging to make "sleeves" for each beaker that are open on the top. Then I store them inside the original box as they came, nestled in a stack and protected by the sleeves. The glass doesn't clink, it's reasonably secure, but still easily accessible. Now, if you've ever done chemistry at university or in a professional setting, you'll know that these aren't "scientific grade" by a long shot. Compared to what you'll find in a laboratory, the glass is rather thin, i.e. may break easily, and the graduations are unsuitably coarse and imprecise. An overall tolerance of 5% is already poor, but given the wide steps of the graduation marks, I'd be surprised if one can get anything better than 10-15% out of these, unless you want a volume matching a mark exactly. For extra annoyance, some of the markings aren't very practical. For example, the 250 ml beaker is marked in 50 ml steps that are divided into 4, not 5, subdivisions, so the small marks go in steps of - you did the math - 12.5 ml! Have fun with that. Also, the graduations are not etched but rather somehow painted onto the surface and will probably wear off with use, which would not happen with pro-quality glassware. But, like I say, they are fine - and priced right - for general, low-precision household use.

This works really well on my magnetic stirrer, and it's a great volume (storage) to work with. Easy to clean, easy to use daily, wish the volume markers were on both sides of the container. I really like the glass, and it seems to hold well with use, no scratches and is still clear.

These are the right size for what I need to do.

good
