Description of the machine

The G 7883 washer-disinfector is a front
loading machine designed specifically
for processing laboratory utensils and
glassware.
In general these include glass, heat
tolerant plastic, stainless steel and
coated metal items such as containers
(e.g. beakers, narrow necked and
conical flasks, Erlenmeyer flasks,
bottles, test tubes, separatory funnels
etc.), measuring vessels (e.g.
volumetric flasks, measuring cylinders,
pipettes etc.), dishes (e.g. Petri dishes,
mortars, watch glasses etc.) and small
components (e.g. stoppers, spatula,
stirrers etc.).
The main aim of processing laboratory
utensils and glassware is to remove
contaminations from both external and
internal surfaces and to rinse off any
cleaning and neutralising agents.
Items are loaded into inserts and
mobile units which are then pushed into
the wash cabinet. The door is then
closed and the programme is started
manually. At the end of the programme
the operator opens the door, removes
the mobile unit and inserts and unloads
the items.

The G 7883 is a single cabinet system
in which the whole process takes place,
including the pre-wash, main wash,
neutralisation, interim and final rinses.
Drying can be selected as an additional
function to complete the process. Each
programme stage follows on
automatically after the previous one.
The main wash, neutralising and rinse
stages are all carried out using water
based agents only. In other words using
cold, hot or fully demineralised water
with the addition of a suitable chemical
agent (cleaning agent or neutralising
agent). Other liquid agents such as
organic solvents or combustible agents
must not be used in this machine.
Before processing anything in this
machine make sure that it is suitable for
machine processing and that it is for
example heat, acid and alkali tolerant.
It is the user's responsibility to decide
whether items contaminated with
substances such as micro biological
material, pathogenic cells, facultative
pathogenic cells, genetically modified
material etc. should be sterilised before
machine processing.
