Introducing our 250 ml Borosilicate ASTM Graduated Cylinder with Guard, designed for accurate measurements in laboratory applications. This Class A cylinder conforms to ASTM standards, ensuring reliable performance. With 2.0 ml graduations and a tolerance of ±1.0 ml, it provides precise volume readings. Crafted from high-quality 3.3 borosilicate glass, it offers excellent chemical durability and can withstand high temperatures and thermal shocks due to its low temperature gradient. The hexagonal base provides stability during measurements. It is also autoclavable at 121°C, allowing for easy sterilization. Compliant with ASTM E1272, this graduated cylinder meets the highest quality standards. For detailed information on temperature and chemical durability, please refer to the specifications tab.
