Cylinders provide accurate measurements even at the lowest graduations. These cylinders are used in ASTM tests D 86 and D447. Models 34200-04 and -05 meet ASTM E 133 requirements. Cylinders are made of borosilicate glass and feature easy-to-read white ceramic scales and handy pouring spouts. Heavy, round bases on the smaller sizes and a hexagonal base on the 2000 mL size ensure stability on your benchtop.
