If you've ever wondered where to buy test tubes, you've found your answer!

Find them in clear glass and clear plastic. HST's glass test tubes are made from strong borosilicate glass and can be heated, and our plastic ones are polystyrene. "Baby soda bottles" come with a screw cap and are kid-friendly for even the youngest scientists. HST offers round bottom test tubes as well as tubes with a conical bottom.

Also find other complementary equipment for your laboratory experiments and science projects. Shop wooden or plastic racks (stands), culture tubes, metal clamps, cleaning brushes, and more.

A lab test tube is ideal for working with small quantities of a liquid. For example, in testing how much vitamin C is in lemon juice or other lab applications.

Test tubes are general purpose and even make fun party favors or stocking stuffers! Need rubber stoppers to fill the ends? Go to our stoppers page. Home Science Tools is your source for all your lab supply needs. Accessibility and a variety of options await you. What are you waiting for? Checkout! Spark Wonder and Discover the Wow!
