Great valueReviewed By: Julie of KY This flask is a great value and the best part is the great price. I love all the glassware from HST and an Erlynmeyer flask is a very usable piece of glassware.

Great QualityReviewed By: Spencer All of the bombex glassware is just as good as pyrex. I've used both, and the only difference is that bombex is cheaper!

Great Packing!Reviewed By: Jennifer Thompson This flask is beautiful and sturdy.
I have ordered lots of glass and other breakables from Home Science Tools, and never has anything arrived in less than perfect condition. They are without a doubt the most careful packers I know.

StylishReviewed By: Jerry I'm homeschooling and all I needed was a beaker but this flask is not only a good item at a good price but it looks more stylish then a beaker. it will make your lab area look like one.

The company was great in letting me ship them back in exchange for smaller flasks and it was all done in a very timely manner which is always a plus.

- Wednesday, May 30, 2007 strong glass Reviewed By: James Scott this glass is very strong and unbreakable, i accidently dropped it and it was fine. but of cource if you smash it it will break but it is over all a great flask, and it heats up well
