6.3 Extended Non-Use and Storage
The Echo liquid handler is designed to be used on a regular basis (daily or
within a week). Regular use keeps the acoustic transducer wet and provides
consistent liquid transfer results.
The acoustic transducer must remain wet to retain the high degree of
precision and accuracy that is required for nanoliter volume transfer. If the
transducer is allowed to dry out, the focal length can change, which can
affect DMSO measure and transfer accuracy.
If you do not plan to use the Echo liquid handler for longer than two
weeks, perform one of the following options:
 If the Echo liquid handler remains connected to the power source,
chiller, air and vacuum lines, then perform the maintenance
procedure described in section 6.3.1.
 If the Echo liquid handler will be disconnected and stored for an
indefinite period of time, then the instrument must be prepared for
storage. See section 6.3.2.
6.3.1 Maintenance During Extended Non-Use
The following procedure assumes that the Echo liquid handler is still
connected to the power source, chiller, air and vacuum lines.
1. Recirculate the coupling fluid once a week. See the procedure “Cycle
fluid through the Echo system” on page 6-13 .
2. Perform scheduled maintenance at two-week and one month intervals.
Call Labcyte Service and Support to schedule six-month maintenance.
See “Maintenance schedule” on page 6-2 .
