In the realm of chemistry, a test tube is a staple piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top and closed at the bottom. Test tubes are used to hold, mix, or heat small quantities of liquid or solid chemicals for assays and qualitative experiments. Their simplicity and versatility make them indispensable in both educational and professional laboratory settings.
Test tubes come in various sizes but are generally small enough to be easily held in one hand. They are often placed in special racks designed to hold them upright to prevent spillage. The design of a test tube allows for the observation of reactions, such as color changes or the formation of precipitates, making them a fundamental tool for chemists to conduct experiments and analyze substances.
