Experimental equipment primarily refers to the instruments and tools specifically designed for students to use in laboratory classes. This includes physics, chemistry, and biology experiment kits for junior and senior high school, as well as individual laboratory apparatus such as microscopes, magnifying glasses, voltmeters, ammeters, test tubes, beakers, evaporating dishes, alcohol lamps, gas‑washing bottles, funnels, graduated cylinders, balance scales, volumetric flasks, and gas‑displacement apparatus.

Test tubes come in various types, including standard test tubes, conical test tubes, and centrifuge tubes. [1] The dimensions of standard test tubes are specified as outer diameter (mm) × length (mm), such as 15×150, 18×180, and 20×200. Centrifuge tubes are designated by their capacity in milliliters.
