Cedex HiRes Analyzer Operator’s Guide
XIII. Warnings and Precautions
Moving parts may cause hand injuries. Never use the Cedex HiRes Analyzer without the protective cover
on the Multi Sampler and Syringe Module.
It is important that the following safety instructions and guidelines be observed in order to ensure safe and
reliable operation of Cedex HiRes Analyzer:
Place the device on a dry and sturdy surface, free of vibrations.
Avoid transporting the device as much as possible once it has been assembled.
Prevent the device from getting wet.
Protect the device from dust and smoke.
Do not expose the device to direct sunlight.
Ensure there is suffi cient air circulation around the Cedex HiRes Analyzer during operation (particularly
around the computer and monitor).
Operate within a constant temperature range of 50°F – 100°F (10°C – 40°C).
For best performance it is recommended to keep the analyzer permanently on and only shut down the
software application on a regular basis.
The Cedex HiRes Analyzer should only be used with the supplied or specifi ed devices (Cedex HiRes
Analyzer, Cedex HiRes Software, monitor, computer, Multi Sampler, Reagent Tray).
Do not install any additional software on the corresponding computer.
Only trained personnel in a controlled laboratory environment should operate the Cedex HiRes Analyzer.
All services and repairs should be performed only by authorized service technicians.
Always ensure that there are suffi cient reagents in the reagent containers.
Clean the containers before reusing them.
Always observe the safety regulations when handling Trypan Blue, Detergent, Cleaning Solution or acids
and bases.
Waste contaminated with tissue or cells, e.g. Cedex Sample Cups, pipette tips, etc., must be disposed of
according to the recommended rules for handling biohazard materials.
Any leaks in the Liquid Management system must be repaired immediately. Contact your distributor or
authorized service technician.
Always ensure that there is a Cedex Sample Cup attached to the single sample port or placed in the Default-
Cup position on the Multi Sample tray.
Only use Cedex Detergent for the cleaning process in the Liquid Management system.
Only use Cedex Sample Cups from Roche Diagnostics GmbH for the conveyance of cell samples to the
sample port.
Other sample cups can cause irreparable damage to the Cedex HiRes Analyzer!
Always wear protective clothing, particularly gloves, when handling samples.
To prevent damage to the fl ow chamber, no particles larger than 80 µm should enter the measurement
system.
Particles ( especially microcarriers) larger than 90 µm should not gain access into the analyzer because they
cause irreparable damage and render the device non-functional.
Dirt or dust particles should not gain access into the device.
Ensure that all equipment required for sample preparation, e.g. Cedex Sample Cups, pipette tips, etc., are
stored in a dust-free environment since coarse dust particles can impair the fl ow chamber’s functionality.
Check that the Cedex Sample Cup is free of contamination before use. Only clean Cedex Sample Cups can
guarantee optimal functioning of the Cedex HiRes Analyzer.
