Test Tubes
Find glass and plastic test tubes, wooden or plastic test tube racks (stands), and other equipment for doing laboratory experiments or chemistry science projects. Glass test tubes are strong borosilicate and can be heated; plastic are polystyrene. Order the Giant packs for kids. Need rubber stoppers to fill the ends? Go to our stoppers page.
Test tubes are ideal for working with small quantities of a liquid, such as testing how much vitamin c is in lemon juice. Read our article for an overview of lab equipment.
