3 Nozzle Head
The nozzle head moves over the processing stage up and down (vertically along the z-
axis). It carries the pipetting unit, the sensor unit and the magnet unit. The pipetting unit
consists of 8 independent working air-filled plungers, each connected to a nozzle (1)
which takes up the Reaction Tip. The Reaction Tip (3) is held by the O-ring (2) on the
nozzle. A specially designed sensor unit checks all 8 channels indiviually for clots in the
sample material, correct position of the reagent cartridge and piercing tool, loss of reaction
tips, as well as for the presence of sample tube and internal control tube (if appropriate).
4 Processing Stage
The processing stage holds the cartridge rack with the reagent cartridges, the tip trays, the
tube rack with elution tube rack, the heating units and the waste tank. It moves back and
forth (horizontally along the y-axis), thereby moving the cartridge rack with the prefilled
reagent cartridges into position so they can be processed. It contains a loading mechanics
that lifts the cartridge rack to the top position for easy insertion and removal of the car-
tridge rack or the cartridges. The equipped cartridge rack is then manually pushed down
to the low position of the loading mechanics inserting the respective cartridge wells into
the heating unit.
5 Touch-screen
From the touch-screen, you can operate all instrument features. E.g., you can program a
run, install a new protocol, maintain the instrument or search for accumulated data. You
can activate the functions on the touch-screen either with your fingertips or with a PDM
pencil.
