Page 16: Sample Racks
3 Sample Racks A sample rack is a sort of turntable for the positioning of beakers which are to be placed on the 717 Sample Changer. Because for titration, various sizes of beakers are common or required, many kinds of racks can be used and are easily interchangeable. The rack offers space for various numbers of samples depending on the diameter of the beakers. - Page 17 3 Sample Racks The standard racks provided by Metrohm are already equipped with a predefined magnetic code for every rack type. If several racks of the same type are used, the magnet rods can be ar- ranged differently so that a unique identification of a sample rack is possible, if this is desired.
