final sequence, which have to be carried out once before the start of a
sample series or once after it has been completed. This offers many
advantages, particularly for titrations. The electrode can be conditioned
before the first titration or subjected to a special rinsing process.
A learn mode is available for creating run sequences and, with its help,
command parameters can be set in manual operation.
Exchangeable standard sample racks are available for many sizes of
beakers and test tubes. Freely selectable "special beaker" positions can
be defined for each rack. These are then used for including rinsing or
conditioning beakers, which can be addressed in any part sequence,
on the rack.
By extending the system with a 786 Swing Head the number of samples
to be processed on a rack can be considerably increased. The robotic
arm of the 786 Swing Head allows any point on a sample rack to be
addressed. This means that the number (max. 999 rack positions) and
arrangement of the samples is virtually unlimited. On request we can
supply customer-specific special racks for individual requirements.
Freely definable position tables can be loaded via the RS232 interface
and suitable PC software for the configuration of special racks.
