Test tubes are small, cylindrical glass tubes with a rounded bottom and an open top. They come in various sizes and shapes, and some have markings on the side to indicate volume measurements. Test tubes are commonly used in chemical experiments to hold, mix, and heat small quantities of liquids or solids. Test tubes are one of the most iconic and fundamental elements in any chemistry laboratory. These simple yet versatile instruments are used in a wide variety of experiments and tests. Below, their use, types, handling, and care in the laboratory are detailed. 1. Description and General Use Description: Test tubes are transparent glass cylinders, open at one end and rounded at the other. Common Uses: They are used to contain, mix, heat, and react small quantities of liquids or solids. 2 ... A test tubes is a versatile piece of laboratory equipment used to hold, mix, heat, and observe chemical and biological substances. Discover its types, uses. Limitations of test tube Restricted volume capacity limits test tubes to sample handling and small-scale reactions. In tests, poor heat transfer qualities can cause unequal heating and temperature control. Especially with glass test tubes , fragile construction raises the possibility of breakage and possible sample loss. Many test tube designs have inaccurate measurements made harder by insufficient exact volume marks. Non-airtight construction could let samples be contaminated or evaporated ...
