Daily Maintenance and Cleaning Routines
The Liquid Management plays a key role in the Cedex HiRes Analyzer. It is necessary to Prime the system at the
beginning of the day, and to carry out an LM Shutdown prior to shut down of the system in the evening (see
“The Hardware Management Dialog Box”).
In addition, the Liquid Management automatically runs an Ultra Fast Clean routine after every sample
measurement. During the Ultra Fast Clean (approximately 30 seconds), the entire Liquid Management system,
including capillary tubes, flow chamber, and sample port, are rinsed out thoroughly.
Manual cleaning routines can be performed in the Cleaning dialog box. To open the Cleaning dialog box, click
on the CLEAN button in the Shortcuts area of the Cedex Control Center or select Cleaning routines in the
Functions menu:

placed in the DefaultCup position on the Multi Sample Tray to prevent flooding.
Ultra Fast Clean (with detergent and distilled water for approximately 30 seconds)
