Glass Test Tubes – Reusable Laboratory Sample Tubes

Glass Test Tubes are general-purpose laboratory vessels designed for holding, mixing, observing and processing small quantities of liquid or solid samples during laboratory procedures, experiments and demonstrations. They typically feature a clear cylindrical body with an open top and rounded bottom, allowing easy observation of samples and reactions. Depending on the specific product, test tubes may be manufactured from borosilicate glass, soda-lime glass or other laboratory-grade glass, with different levels of chemical and thermal resistance. Glass test tubes are widely used in medical, clinical, research, pharmaceutical, educational and industrial laboratories for sample handling, small-scale reactions and other routine laboratory applications. Key Features Clear transparent glass construction Cylindrical tube design Rounded bottom on standard models Open top Allows easy observation of samples Suitable for small-volume laboratory work Reusable where applicable Available in different diameters and lengths Available with plain or rimmed tops Suitable for a wide range of laboratory applications
