50ml Narrow Mouth Erlenmeyer Flask, Borosilicate Glass, Heavy Duty Rim, Thick Wall, Karter Scientific 213G26 (Single)

My son uses this for at home science projects, he is very happy with it and likes the thick feel of the glass.

The graduations are easy to see. I found the white markings really help with darker chemicals. My application doesn't require precision, but still, it is nice that the graduations are very easy to see and use. The glass is thick so maybe it will not shatter if I drop it, who knows, I will be careful as I don't want the clean up.

I got exactly what I expected. With a product like this, you get EXACTLY what was described.

I'm not really doing science with this - I bought it to use with The Smoking Gun hand-held smoker - so that I can add smoke to cocktails! This is perfect for this use . . . and, I guess, at least for me - it's science!

It came very promptly, and was just what I needed to demo a volcano for my first graders.

It's a beautiful flask, even for a flask. But it works equally well as an art object. Bought it for my daughter, who has an odd obsession with lab gear. (It could be a lot worse!) But even if you want it for its intended purpose, it's just fine. Reasonable price too!

I was looking for a replacement for an antique bottle with rubber stopper that I use to serve cream in for my B&B. This is perfect. I will be ordering a larger one for summer when I have more guests to feed.

Exactly what I expected it to be! Arrived not broken, arrived quickly, truly amazing.
