Test Tube 10ml, Graduated with Stopper, Borosilicate Glass, Each

Livingstone Graduated Test Tube with Stopper, 10ml is crafted from high-quality borosilicate glass (GG17), ensuring durability, precision, and reliability in laboratory use. Designed for safe sterilisation, this test tube is autoclavable and ideal for applications requiring consistent performance under heat and chemical exposure. With a softening point of around 820°C and stable operating temperature below 450°C, it provides strong thermal shock resistance and withstands sudden temperature shifts without stress-induced cracking. Compared to standard soda-lime glass, borosilicate glass offers superior mechanical strength, excellent chemical stability, and a low expansion coefficient (3.3×10-6/°C), making it the preferred choice for demanding laboratory environments.
