8. MAINTENANCE
Besides regular cleaning, the device is basically maintenance-free.
For cleaning the units only use alcoholic media, not acetone or xylene.
For the housing it is best to use a commercially available cleaner for
plastics. The housing should not come in contact with alcoholic or
other solvents.
Never spray or use cleaning medium directly onto operating foils.
Please take note of the safety aspects of the device.
Wear protective clothing and disposable gloves according to Good
Laboratory Practices.
Some general instructions for paraffin:
Paraffin is flammable and therefore must be handled with care. Avoid spillage of liquid
paraffin.
All components of the Slee embedding center MPS P I and MPS P II that come into contact
with paraffin and the interior of the devices are carefully sealed to prevent wax from
entering. Nevertheless, if paraffin is spilled, it should always be removed carefully.
The paraffin tank and the cassette bath, if required, should be filled with care. Avoid
overfilling.
The paraffin in the cassette bath must be exchanged every day to avoid contamination.
Solid paraffin particles on the surface of the work area must not be removed with sharp
tools, as this could damage the finish. A soft plastic spatula is ideal for paraffin removal.
Alternatively, solid paraffin can be lifted off easily by lightly warming it.
To clean the paraffin tank, it can be lightly warmed up and the paraffin block can be
removed. Alternatively, it can be flown out completely through the arm. The reservoir is
cleaned inside with a paper tissue. Care should be taken that the reservoir is
contaminated. Any dirt inside should be removed.
For cleaning of the forceps holders, they can easily remove. They are fixed with magnets
onto the housing. They are frequently a source of contamination and are susceptible to
dirt. Therefore, they should be cleaned thoroughly. They are heated during operation
through the placement onto the work area and they are thus very hot (approx. 80 °C).
The paraffin collection tray is to be checked daily. The paraffin should be emptied regularly
to ensure that excess paraffin can drain to the tray.
