The Best Test Tubes You Can Buy

Test tubes are versatile tools. Whether you need them for a laboratory, a school science project, for growing plants, storing liquids and powders, or even holding party favors, test tubes provide many practical uses. Here are some options we recommend.

What to Consider When Buying Test Tubes

Here’s what to think about before purchasing a set of test tubes:

• Volume: Determine if the tube’s volume will hold enough product for the intended use.
• Use and Material: Do you need the test tubes for liquid or powder storage, chemistry projects, or plants? Certain uses will require certain materials; for example, if you need to heat the test tubes under high heat, you’ll want glass ones instead of plastic ones so that they don’t melt.
