6.1 Beaker sensor

Every tower of a Sample Processor is equipped with a beaker sensor

detecting the availability of a sample vessel in front of the tower. An infra-

red sensor identifies devices of various materials if they are located in a

correct position in the front of the tower. In the rack configuration of the

control device or the control software, the setting 'Beaker sensor' Tower

must be selected. The beaker test is carried out whenever a rack position

is moved to in a method run.

The beaker sensor on the tower can only be used with single-row sample

racks.

6.2 Rinsing nozzles

Using rinsing nozzles is very effective in order to rinse sample vessels (with

sensors and buret tips) efficiently. Rinsing nozzles are available in two

model versions:

￭ 6.2740.020 spray nozzle

For the fine-spraying of the rinsing solution. The nozzle has a small ball

at the opening. The distribution (but also the backpressure) of the rins-

ing liquid is clearly higher than the one of a rinsing nozzle.

￭ 6.2740.030 rinsing nozzle

The rinsing liquid is applied as a fine jet for optimal removal of layers

on electrodes and on titration accessories.
