Glass Boiling Tubes – Heat-Resistant Laboratory Tubes

Boiling Tubes are laboratory glassware designed for heating, boiling, mixing and holding relatively small quantities of liquids and chemical solutions during laboratory experiments and procedures. They resemble standard test tubes but are generally larger and more robust, providing additional capacity for heating and conducting reactions. A typical boiling tube has an open top, cylindrical body and rounded bottom. Heat-resistant versions are commonly manufactured from borosilicate glass, which provides good resistance to thermal shock and many chemicals used in routine laboratory work. This makes them useful for experiments involving controlled heating, subject to the manufacturer's temperature and handling instructions. Boiling tubes are widely used in educational, research, medical, pharmaceutical and industrial laboratories. Key Features Larger than a conventional test tube Designed for heating and boiling compatible liquids Clear glass for easy observation of contents Heat-resistant construction when made from borosilicate glass Cylindrical body Rounded bottom Open top Reusable Easy to clean Suitable for mixing and conducting small-scale reactions
