Practical experience combined with expertise
Typically Miele
Manual v. machine-based reprocessing
Many laboratories have deliberately chosen to wash their laboratory glassware,
e.g. beakers, pipettes, volumetrics and
flasks, Erlenmeyer flasks, Petri dishes and
test tubes, in a machine-based process.
One reason for this is to avoid the risk of
exposure to hazardous substances.
Broken glass from manual cleaning, for
instance, can cause serious injuries. Infectious and toxic contaminants pose a health
hazard. Cleaning agents often contain
substances that are highly irritant.
Automatic, machine-based processes are
also more easily standardised, validated
and documented. Because washer-disinfectors operate as a closed system with
programmes that run fully automatically,
the potential risk to laboratory personnel
can be kept to a minimum. This in turn
means that machine preparation provides
personnel with maximum protection.
Laboratories use a wide variety of equipment made from glass, ceramic ware and
plastic for testing and analysis, creating
reactions, for isolating or cleaning substances and for taking samples, etc.
Following on from this, cleaning and drying
are essential. The cleaning process must
ensure that equipment, when re-used, is
not affected by its previous use. Requirements vary widely from one laboratory to
the next. To establish which machines and
accessories, cleaning agents, water quality
and cleaning programmes best suit an
application, the following aspects need to
be considered:
1. Applications
Applications subdivide into general areas
(organic, inorganic or physical chemistry,
biology, microbiology, hospital, pharmaceutical, food industry or cosmetic industry
laboratories, etc.). The type of application
will also be an important factor in determining the type of machine and accessories as well as the cleaning process and
cleaning agents required.
2. Laboratory machines
Laboratory equipment needs to be classified according to its various components
(beakers, conical flasks, measuring flasks
and cylinders, pipettes, Petri dishes, test
tubes, phials, centrifugal test tubes, etc.),
and according to size and volume (1 ml,
500 ml, 1000 ml) and the number of items
requiring processing. This information will
enable us to quote the right system for
your requirements.
5
3. Contamination
An intimate knowledge of the physical and
chemical attributes of the contaminants
the machine will need to deal with is of
particular importance in choosing the most
appropriate cleaning process and detergents.
Physical and chemical properties of a contaminant include, for instance, its solubility
in water in acidic, pH-neutral and alkaline
conditions, the efficacy of hydrolysis or oxidation, melting and softening points, its
ability to emulsify as well as a substance’s
suspension or dispersing properties.
4. Disinfection
For certain applications laboratory glassware has to be disinfected. On the one
hand this protects laboratory personnel
who come into contact with bacterial
contamination at work. And on the other,
disinfection prevents bacterial cross-contamination of test samples and instruments
in medical laboratories, hygiene institutes
and pharmaceutical laboratories in the
food and cosmetics industry.
5. Analytical Methods
The results of analyses can be falsified by
contaminants on laboratory glassware.
Knowledge of these factors can help in
selecting the correct cleaning agent.
6. Analytical purity
Each laboratory has its own definition of
“analytical purity”, depending on specifications and the nature and reproducibility of
test methods. The washer-disinfector, including all its accessories and the cleaning
programme used, must be able to achieve
cleaning results that meet the standards
required by the application.

NEW: G 7893 lab washer
with Drying Plus
Miele, innovation leader in glassware
reprocessing, is the first manufacturer to
offer a 60 cm wide washer-disinfector with
integrated “Drying Plus” hot-air drying.
Miele’s new machine concept enables
comprehensive instrument reprocessing
comprising thorough cleaning, safe disinfection and effective drying. All mobile
units with a drying unit connection (TA)
support the drying of inner surfaces as well
as external drying.
Even intricately shaped glassware is properly reprocessed thanks to Miele’s hot-air
drying. An integrated HEPA filter (S class
EU 12) guarantees the purity of the air
used for drying. Filters are replaced simply
and conveniently by opening the service
hatch at the front of the machine to remove
the filter.
Miele’s new G 7893 washer-disinfector
meets all requirements, offering Miele’s
proverbial quality – Made in Germany.

Fully electronic controls, excellent
process security
Programmes and functions on Miele washer-disinfectors G 7883 and G 7893 CD are
reliably controlled and monitored by
MULTITRONIC controls. The majority of
routine reprocessing tasks are covered by
standard washing and disinfection programmes. Process parameters, reprogrammable within the individual blocks that
constitute a programme cycle, allow
further customising to cater for individual
needs. The serial RS 232 interface (depends on model) allows all process data to
be ported to a printer or PC for documentation. The protocol contains key programme data such as running times,
temperatures, dispensing and information
on errors and manual intervention.
Excellent user convenience
Self-explanatory symbols on fascia panel.
The machine status is indicated at any
given time via control lamps. A 3-digit
7-segment indicator in the display with its
own toggle switch can be used to display
the remaining programme duration or the
current washing/disinfection temperature.
Status and control indicators monitor the
process and inform of faults and the need
for servicing.

High performance, efficient use of
energy
High performance, economical Miele
washer-disinfectors offer a large inner
cabinet with 2 wash levels (upper and
lower baskets) for laboratory glassware
and accessories. Direct docking of the
upper basket onto the water circulation
system reduces water consumption per
cycle. Even the water entering the machine
is carefully metered. A flowmeter monitors
water intake quantities and thereby
ensures precise detergent concentrations.
Water and effluent costs are therefore
reduced accordingly.
