Description of the machine

The G 7804 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
contamination from both external and
internal surfaces and to rinse off any
cleaning and neutralising agents.
The G 7804 is designed to process one
batch at a time. 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 7804 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.
