2.5 Racks
A sample rack is a sort of turntable for the positioning of beakers
which are to be placed on the Sample Changer. Because for titra-
tion, various sizes of beakers are common or required, many kinds
of racks can be used and are easily interchangeable. The rack of-
fers space for various numbers of samples depending on the
diameter of the beakers. Metrohm delivers the following predefined
types of standard racks:
Every single rack can be identified by a unique magnetic code.
Rod magnets which are attached to the bottom of the rack can be
combined to form a 6-place binary code. The sample changer can
then automatically recognize the mounted rack. This is possible
when the rack is positioned with the first rack position under lift 1.
After changing a rack, the sample changer should first be initial-
ized by pressing the <RESET> key or turning the instrument off
and on. This way the save recognition of a rack and therefore the
correct beaker positioning is made possible.
