These are very useful when working with the test tubes. Great price!
Simple but effective
Review by Duane
No bells or whistles...but then again it does it job simply and effectively. I bought two so each of my kids has one available for their experiments. I may need to buy another one since my son is pretty sure he can incorporate it into one of his Lego designs!!

Review by Deb
I bought these based on the recommended items needed for Apologia Human Anatomy & Physiology. Great price and will work great for the activities planned by Apologia. The kids feel like real scientists using this with the test tubes.
a must have!

This test tube clamp is a must have! It holds a variety of sizes of test tubes and makes it easy to hold hot test tubes over a heat source. I recommend this item.
