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.
Very durable and very useful

When I received this clamp it was a lot bigger than I thought it would be. It was very strong and very durable. This was great for heating things in flames while moving the test tube around to ensure even heating. It was a great buy, very cheap and will definitely last you a long time.

This clamp is very handy for holding a test tube over an open flame whenever you want to demonstrate a small scale reaction that requires heat. This is a great buy.
