Fluid Chiller - Labcyte Echo 520 User Manual

3.2.11 Fluid chiller

Another essential component of the Echo liquid handler system is the fluid
chiller. This component draws water from the coupling fluid bottle, adjusts
the fluid temperature, and circulates the fluid through the acoustic
transducer.
Coupling fluid temperature control
Correct Echo liquid handler coupling fluid temperature is 22.0°C. This
temperature can be monitored on the D
handler software application.

Set the fluid chiller to 22.0°C. See Appendix C for chiller instructions.
3.2.12 Surge tank
A 10 L surge tank is standard with the Echo liquid handler system. When
vacuum demand is at its highest, the surge tank ensures a continuous
source of vacuum. It prevents system errors resulting from low vacuum in
laboratories where house vacuum barely meets the minimum vacuum
requirement or is inconsistent due to other laboratory demands. Surge
tanks are available for purchase for older Echo units.

Caution: Incorrect fluid temperature can reduce the precision and
accuracy of the fluid that is transferred, and potentially damage the
acoustic transducer. Ensure that the chiller is correctly connected to
the Echo instrument and is running at recommended temperature.
