Four Test Tubes and Rack
This is a perfect way to start your own science lab at home. It is also a great way to help students observe science in action. Includes four large, unbreakable plastic test tubes with caps and a sturdy test tube rack that allows you to see everything going on in the test tubes.

Our test tubes are "preforms." They are the early stage of a 2 liter soda bottle. Each preform test tube measures approx. 5.75 inches (15cm) tall, and each holds about 2 ounces (60 ml.)

Test tube racks are available in green, red, blue, or yellow.
