GLASS TEST TUBE WITH STOPPER

Glass test tubes are fundamental laboratory tools used for holding, mixing, and heating chemical substances. Typically made from high-quality borosilicate glass, these test tubes offer excellent thermal resistance, making them suitable for use in a wide range of temperatures without risk of breaking. The smooth, cylindrical shape with a rounded bottom allows for easy handling and uniform heating, while the open top facilitates the addition of substances and easy observation of reactions.

Glass test tubes come in various sizes, ranging from small tubes used for qualitative analysis to larger tubes for more significant quantities of samples. They are widely used in chemistry, biology, clinical, and educational laboratories for experiments, chemical reactions, sample storage, and more. Glass test tubes are favored for their clarity, chemical inertness, and ease of cleaning, which makes them reusable and ideal for precise scientific work.
