To ensure reliable operation of the ZE5™ Cell Analyzer and accuracy of experimental results, perform
preventive maintenance regularly.
Important:
Always follow the personal protective equipment (PPE) guidelines relevant to your
laboratory's safety procedures for handling the chemicals recommended in this section and for
any biohazards encountered during instrument maintenance, including the waste bottles.
Recommended Maintenance Schedule
Daily
The system must be shut down through the software on a daily basis. If the system is not shut down
properly at the end of each day, it might be prone to contamination.
During the shutdown procedure, the sample line, probe, and flow cell are cleaned automatically with
the onboard cleaner. If additional cleaning is needed, it can be run prior to the shutdown process. See
Cleaning the Sample Line and Probe on page
regarding approved cleaners for the system tubing.
To perform the system shutdown procedure
1.
Ensure that the onboard cleaner bottle contains sufficient fluid.
2.
Click Shutdown in the Home window to initiate the automatic shutdown process. For more
information, see
Weekly
Each week, wipe down the system with a mild disinfectant. Clean any debris or buildup on the loader
stage and surrounding area. Inspect the bulk fluidics area for any drips or buildup and clean the area.
Inspect the levels of cleaner and sheath additive to ensure that they are sufficient for system usage.
When you fill the cleaner and additive bottles, the fluid level must not exceed the half-full mark on the
bottles.
