2.8 Sample racks
A sample rack is a turntable which accommodates sample vessels and
which is placed on the sample changer. As in titrations or measure-
ments various sizes of sample vessels are normal or necessary, differ-
ent types of easily exchangeable sample racks can be used. The num-
ber of sample vessels which can be accommodated on a sample rack
depends on their diameters.
When used with the 824 Easy Sample Changer the highest rack posi-
tion is intended to be used for a special beaker for rinsing or condition-
ing/dipping.
Metrohm supplies the following standard sample racks:

Each sample rack is unambiguously identified by a magnet code. Mag-
netic pins, attached to the base of the rack, provide a 6-place binary
code. This means that the magnet sensor can automatically recognize
the rack that is attached when the first beaker position is in front of the
tower.
