- Wednesday, March 27, 2013Good tubesReviewed By: Jack
The quality is excellent for homeschool, the price is very reasonable, and the packing was done well so that none broke during shipping. I haven't heated them so I don't know how they will stand up to a flame. Shipping was faster than I expected. HST's does an excellent job!

They are perfect for 1st yr. chemistry class. After searching other companies, Home Science Tools was by far the best value.
- Monday, August 15, 2011smaller than "normal"Reviewed By: Rachel Biagioli
These are not the "standard" ones that you use in a rack. They are much smaller. I didn't realize the size. but, they seem well made and will do small jobs!

If you're going to be performing high exothermic reactions like making lithium chloride from hydrochloric acid and lithium, don't buy these, they break at those temperatures.
