This Miele commercial dishwasher can be used to reprocess
laboratory glassware and laboratory utensils with water based media.
The process includes cleaning and rinsing. Due to the wide variety of
laboratory glassware and laboratory utensils on the market, it may be
necessary in some cases to establish whether it is suitable for
reprocessing in a dishwasher. This will depend on its use and the
type of soiling present. Please also observe information provided by
the manufacturer of the laboratory glassware and laboratory utensils.
Laboratory glassware and laboratory utensils suitable for
reprocessing include a range of items from evaporating dishes to
centrifuge tubes, for example:
– Vessels such as test tubes, beakers, flasks, etc.
– Measuring vessels such as measuring cylinders, volumetric flasks
etc.
– Dishes such as petri dishes, watch glasses, etc.
– Plates such as slides, sequencing plates, etc.
– Small items such as lids, spatulas, magnetic stirring rods, stoppers,
etc.
– Other items such as funnels, pipe/hose pieces, etc.
Pipettes are not included in this list. They are not suitable for
reprocessing in this commercial dishwasher.
Examples of application areas:
– Laboratories in schools, colleges and universities,
– Different areas of inorganic, organic, analytical and physical
chemistry,
– Biology (excluding agriculture soiling).
Laboratory glassware and laboratory utensils for reprocessing are
referred to as the wash load if they are not more closely defined.
Processing conditions must be suitable for the wash load and for the
type of soiling.
Chemical agents must be suitable for the type of soiling and for
methods of analysis being used.
Intended use
7
The use of a suitable carrier (mobile unit, basket, module, insert, etc.)
is important to ensure the adequate cleaning of the load. Examples
are given in the section "Areas of application".
This machine is programmed to carry out the final rinse with mains
water or with processed water of a quality to suit the application (e.g.
purified water, fully demineralised water or demineralised water).
It is particularly important to ensure the appropriate water quality for
the rinse and final rinse of items for analytical purposes.
The machine can be qualified for process validation.
The machine fulfills the requirements of Directive 2006/42/EC on
machinery

User profiles
Daily operators must be instructed in operating and loading the
machine and trained regularly to guarantee safe daily use. They
require knowledge of machine reprocessing of laboratory glassware
and utensils.
Tasks for daily routine operation are located in the Settings menu.
This menu is freely accessible to all users.
More advanced tasks, e.g. interrupting or cancelling a programme,
require more detailed knowledge about the machine reprocessing of
laboratory glassware and utensils.
Alterations or adaptations of the machine, e.g. accessories used or
on-site conditions require additional specific knowledge of the
machine.
Validation processes assume specialised knowledge of the machine
reprocessing of laboratory glassware and utensils, of the processes
involved and of applicable standards and legislation.
Administrative processes and settings are allocated to the Further
settings. This is protected from unauthorised access by a code.
