Stoddards Test Tube Clamp with Finger Grips – Steel Wire Brass Finish – 5 Inch Length

It is a clamp that holds a test tube — for instance to hold a test tube while heating it without getting burned. It is made from a thick piece of metal wire that is shaped into a spring-loaded clamp to securely hold a test tube.

Note the difference between a test tube clamp, and a test tube rack.  A clamp is a way to hold a single test tube while heating the contents inside without actually touching the test tube itself.  A rack is instead used to hold many test tubes at once in an upright position
