    • Great little set of 3 flasks

Nice priced set of 3 flasks. The sizes vary, and so does the mouth so multiple size stoppers will be needed if you want to use them. The quality seems fine, with thick rims. I've just started using and have only heat steamed them for light purification. This went well with nothing to report. Overall, good started kit or addition to existing if you need a few sizes. ... show more

Size: 50/150/250ml Style: Set
Good quality, but when I got the package the labels on the flask were covered in dust, however a rinse of water cleaned it off just fine.

    • Perfect for Science Experiments!
Size: 250ml Style: Pack of 6
These narrow mouth flask made my 5th grade Elephant Toothpaste experiment amazing! The narrow top allowed my students to see the foam rise and spill over the narrow top. As a teacher, I was so happy with the weight and sturdiness of the flasks. They cleaned up beautifully and I’ll be able to keep them year after year. ... show more

    • Barbie flasks-as my wife calls them!
Size: 5ml Style: Pack of 2
Lovely cute little Erlenmeyer flasks! Bought for use in a melting point application, the size is perfect for my Fisher-John’s Melting Point apparatus. Can also be used for vaporizers at 1620 hours if your interests lie there. Between construction and size, more durable than larger volumes.

Size: 50/150/250ml Style: Set
Best option in my opinion for the price. I have even dropped them more than one time on the concrete floor in my shop and both times they simply bounce without breaking. These beakers are my favorite and I use them any chance I get.
