Cylinder, Measuring, Class B with spout

The Class B Measuring Cylinder with Spout is a precision laboratory instrument used for measuring liquid volumes with moderate accuracy. Made from high-quality borosilicate glass or durable transparent polymer, it is compliant with ISO 6706 / ASTM E1272 standards for Class B accuracy. The cylinder features permanent, easy-to-read graduations and a tapered spout to facilitate smooth, controlled pouring of reagents or samples without drips. Class B tolerance ensures dependable readings where analytical-grade accuracy is not required, making this measuring cylinder ideal for general laboratory applications, including sample preparation, chemical mixing, and volumetric transfers. The hexagonal or round base provides stability and minimizes tipping, while the non-wetting inner surface allows for complete drainage of measured liquids. Available in a wide range of capacities, from 10 mL to 2000 mL, these cylinders are autoclavable, resistant to thermal shock, and suitable for most aqueous and organic chemicals.
