3.2.13 Fluidics panel
The fluidics panel contains tubing and hose connections to the following
components:
Figure 3.20 Fluidics panel
 Chiller tubing. The chiller tubing provides the coupling fluid
circulation path between the Echo liquid handler and the chiller. The
chiller maintains the fluid temperature at 22°C.
Tubing is sufficiently long to allow the chiller to be placed on the floor
below the Echo liquid handler (for reduced vibration and good
ventilation).
 Compressed air line. The compressed air line connects an external
air supply to the Echo liquid handler. Two Echo liquid handler
mechanisms use compressed air: process door and ionizer bar.
Air pressure must be between 80 to 150 psi.
 Vacuum line. The vacuum line shown in Figure 3.20 connects the
Echo liquid handler to the surge tank, and then to the vacuum supply.
The vacuum lines inside the Echo liquid handler pull coupler fluid back
from the acoustic transducer and return the fluid to the coupler fluid
bottle. Another vacuum line removes coupler fluid from the bottom
of the source plate just before it is unloaded. Vacuum flow depends
on the vacuum source (house or pump). See vacuum specifications on
page 3-18 .
