What Is the Test Tube with Rim Used For?
Students reach for the Test Tube with Rim when they carry out qualitative tests: adding a reagent drop by drop, watching for a colour change, a precipitate or gas bubbles, and warming the mixture over a burner. The generous size leaves room for a glass rod, a thermometer or a small piece of solid, and the transparent wall lets the whole group see what happens.
For safe heating, grip the tube with a holder near the rim, tilt it, point the mouth away from everyone and keep it moving through the flame. Let the glass cool in a rack before washing, and clean it with a tube brush so that no residue is carried into the next test.
