Test Tubes
Test tubes are available rather economically with us in a multitude of lengths and widths to serve a varying number of medical, surgical, and laboratory requirements. A test tube, is a piece of laboratory glassware composed of a finger-like length of glass tubing, open at the top, with a rounded U-shaped bottom. Disposable test tubes are also available in various materials and dimensions to meet the diverse requirements of laboratory. These are typically used by chemists to retain multiple discrete samples of materials, generally liquids during various chemical procedures and experiments and are designed to allow easy heating of these samples.
