Glass cylinder – 0025mL
Professional Grade Borosilicate Laboratory Glassware is a type of glass with the main glass-forming constituents silica and boron oxide.
Borosilicate glasses are known for having very low coefficients of thermal expansion (~3 × 10−6 /°C at 20°C), making them resistant to thermal shock, more so than any other common glass. Such glass is less subject to thermal stress and is commonly used for the construction of laboratory measuring cylinders, beakers, flasks, test tubes and funnels.
