Reaction Tray Mixers; Reaction Tray Wash Mechanisms - Siemens ADVIA 2400 Operator's Manual

The RRV contains 340 reusable cuvettes (20 sets of 17 cuvettes).
The RRV cuvettes are immersed in the reaction tank in an oil-heat bath. This keeps the
cuvettes at a constant temperature of 37°C for sample analysis.

Reaction tray mixers

Figure 1-14 Reaction tray mixers
The reaction tray (RRV) mixers (MIXR1 and MIXR2) stir the contents (sample and
reagent) of RRV cuvettes brought to their respective mixer positions.
Mixing is performed using a spinning, reciprocating, and vibrating paddle. Strong and
weak stirring options are available.
Both mixers are located behind the reaction tray. MIXR1 mixes sample with reagent 1
(R1). MIXR2 mixes sample with reagent 2 (R2).
