Applications and loading
This laboratory glasswasher normally requires a top and a bottom basket.
Depending on the type and shape of the glassware, inserts can be supplied and there is a range of other baskets for special applications. The diversity of the inserts is so great that it is not possible to illustrate them all or give de- tailed instructions on their use here. As an example there are inserts for direct injection spraying of volumetric flasks, butyrometers, pipettes etc.
General glassware used in labora- tories, e.g. beakers, conical flasks, test tubes, etc., can be arranged in full- size, half or quarter inserts in top or bot- tom baskets. Your Miele laboratory dealer will advise on specific require- ments.
The following instructions relate only to basic preparation and loading of glass- ware.
Loading the machine
Removing excess soils
Empty all glassware before loading into the machine. Take any hygiene measures necessary against infec- tion.
Ensure that no acid or solvent residues, especially hydrochloric acid or chlorides get into the wash cabinet.
Remove all agar residues from petri dishes.
Remove blood clots and residues from test tubes, etc.
Remove all stoppers, corks, labels, sealing wax residues, etc.
Notes
Load the glassware so that water will come into contact with all surfaces. This ensures that they will be properly cleaned.
Do not place items to be cleaned in- side other pieces where they may be concealed.
Hollow vessels such as beakers, measuring cylinders, flasks, etc. should be inverted and placed in the correct inserts. A cover net can be used to reduce the risk of movement during the wash process.
Petri dishes and similar should be placed in the correct insert with the soiled side facing the centre.
Pipettes should be placed with the mouthpiece facing upwards.
Deep based items should be placed at enough of an angle for water to run off them freely.
Tall, narrow, hollow pieces should be placed in the centre of the basket to ensure good coverage of water.
Do not cover the funnel in the middle of the top basket. Mobile injector units or baskets with an adapter must engage correctly, (see below).
