1 Cleaning and Maintenance Checklist
This checklist provides information about when each cleaning and maintenance routine should be done.
Perform these routines on a daily basis:
c
LM Shutdown: Always after the last measurement and before the Cedex HiRes Analyzer shutdown.
c
Standard Clean: After the final measurement of a set of samples or before a longer pause between
measurements.
c
Chamber Clean 2: At least twice per day.
Carry out this routine on a weekly basis:
c Intensive Clean
c Change of Trypan Blue solution
The following routine should be done every week for users that refill reagents themselves:
c Empty the reagent containers and the waste container.
c Thoroughly clean the containers.
c Refill the reagent containers (see “Refilling Containers Individually”).
Carry out this routine twice per month:
c
Special Intensive Clean: At least twice a month with 0.1 to 1 N HCl instead of detergent.
Carry out these routines on a regular basis (once a week or after 250 measurements):
c Clean the casing, Reagent Tray, Multi Sampler housing (if installed), and Reagent Port by wiping down with
70% alcohol and a lint-free cloth.
c Run a focus adjustment of the Analyzer every month or after any change of position or vibration of the
measurement system.
In order to ensure that the Cedex HiRes Analyzer is fully operational, an Intensive Clean must be carried out
once per week even if the system is not being used for measurements.
