Description

Test tubes are cylindrical, open-ended containers commonly used in laboratories for holding, mixing, and heating small quantities of liquids or solids. They are typically made of glass or plastic and come in various sizes and shapes, including round-bottom, flat-bottom, and conical. Test tubes are essential tools in chemistry, biology, and medical laboratories for a wide range of applications, including chemical reactions, sample storage, culture growth, and diagnostic testing. They can be used standalone or placed in test tube racks for organization and stability during experiments. Test tubes are versatile and widely used in scientific research, education, and industrial processes.
