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).
