Cuvette Washer
Figure 4-4
Its function is to wash cuvettes once the reactions have been measured. This washing is also performed
as required by dispensing: each time a new sample is dispensed by the probe, the washing system
operates, and cuvettes are washed automatically and sequentially. The washer is divided into 4 double
capillaries: one to aspirate, another to dispense liquid, and two drying capillaries. They carry out the
cuvette washing and drying process.
Washers:
Four stainless steel capillaries which aspirate and dispense washing solution. The first capillar
will aspirate the pure reaction.
Dryers:
Two stainless steel capillaries covered with silicone tubing that are placed on the left of the
cuvette washer to dry the cuvettes which have already been washed. They work with two separate
pumps.
Each cuvette is washed by 2400 µl.
This circuit operates sequentially, acting on the cuvette to be cleaned in six stages:
In the first stage, the reaction liquid is aspirated and wash solution is dispensed into the cuvette.
In the second, third and fourth stages; the wash solution dispensed in the previous stage is aspirated
and new wash solution is dispensed.
In the fifth stage, the wash solution dispensed in the fourth stage is aspirated, leaving the cuvette empty.
In the sixth stage, the final drying is done, and the residual wash solution remaining from the previous
stage is completely removed.
