Product Description
Product Description
This three-piece graduated cylinder set includes 50mL, 100mL, and 250mL measuring cylinders made of high-quality Borosilicate 3.3 glass. Each cylinder meets Class A tolerance as per ISO/ASTM E1272 standards, providing reliable volumetric measurements. The cylinders feature blue graduations, hexagonal bases for stability, and spouts for easy pouring.
Each cylinder is fitted with a removable plastic protective collar. The set is packaged in a custom-fit, thick foam casing for safe storage and transport. The borosilicate glass construction is microwavable and autoclavable, with superior chemical durability and a low temperature gradient capable of withstanding high temperatures and thermal shocks. Heat tolerances include a strain point of 515 °C, annealing point of 565 °C, and softening point of 820 °C.
