5.4 – Liquid handling.
handling .
Two syringe pumps and two peristaltic pumps perform all liquid handling.
Each pump has its own defined task. The syringe pumps are used for sample
mixing in the cuvette and for sample dispensing (liquid circuit I; Figure 5.23).
These are also used for liquid handling from the buffer flask to the cuvette
(liquid circuit II; Figure 5.24). The two peristaltic pumps are used for washing
and draining the cuvette (Figure 5.25).
The liquid handling in the Autolab ESPRIT instrument is shown below.
