DURAN® Measuring cylinders are for holding measuring varying amounts of liquids. Available in two different accuracy Classes – Class A with main ring points graduation and Class B with line graduation. For additional differentiation, the measuring cylinders with accuracy Class A have a blue graduation whereas the B Class measuring cylinders a white graduation. Volume content tolerances for measuring and mixing cylinders conform to DIN and ISO accuracy limits. Thus the desired concentration can be precisely created. Measuring cylinders with a batch number and accuracy Class A are supplied with a batch certificate. This certificate documents the mean value obtained from measuring the batch in question, the standard deviation and the day of issue. The batch certificates can also be retrieved online. The batch number consists of four digits. The first two numbers specify the production year, and the following two numbers specify the batch, e.g.: 18.01.
特點和優勢
