Product description

This 15 mL graduated glass test tube is equipped with a well‑fitted ground‑glass stopper to prevent liquid leakage and volatile substance evaporation. Clear permanent scale markings are printed on the tube body for accurate visual volume reading. Constructed from high‑quality borosilicate glass, the test tube delivers good heat‑resistance and chemical corrosion resistance, suitable for most common laboratory reagents. The round bottom design supports routine operations such as liquid mixing, sample holding and reaction testing. Perfect for school chemistry labs, scientific research laboratories and home science experiments. The ground‑glass stopper can be tightly sealed, making it also available for short‑term sample preservation.
