bright light source with optical devices! Do not look directly
into the light source. Fire hazard!
Lenses in optical devices can cause considerable damage due
to the "burning glass effect" if improperly handled or stored!
Make sure that optical lenses are never left in the sun without
a cover!
Use the supplied cover!
Certain surfaces of the device are hot during operation and
can cause burns if touched.
Do never fill xylene into one of the MPS devices.
Flammable substances should never be placed near to the
device.
The device may only be operated by trained specialists.
Paraffin is flammable and should be handled with care. Spillage should be avoided.
Paraffin on the surfaces must not be removed with sharp tools as it would ruin the coating.
It should be avoided to allow xylene to react on all surfaces.
Xylene is a flammable organic solvent. Its flash point is between 27
and 32 °C. Xylene vapors are heavier than air and can easily catch fire
on hot surfaces or sparks even over a greater distance.

7.7HEATED PARAFFIN (WAX) CONTAINER (MPS P and MPS P I module)
i
For a robust performance of the device the flow of molten paraffin
is exclusively driven by gravitation. To assure a rapid flow, please
refill the paraffin container before it empties completely.
The design of the MPS P and MPS P I allows two ways of working with your device.
The first common one is using the timer, which is explained in chapter 7.6 TIMER. This
allows you to have a ready to use unit in the morning with liquid paraffin in it. Therefore,
adjust the start time for tank heating with an appropriate lead time.
Another way is starting the heating manually by going to the Main Menu and activate the
paraffin heating by pressing after you went down the menu with (see cursor
position in table below). After pressing again the status (On or Off) starts blinking and
can be regulated by or .
One line below you can adjust the paraffin tank temperature and another line beneath

7.8 HEATED WORKING AREA (MPS P and MPS P I module)
As mentioned in chapter 7.7 HEATED PARAFFIN (WAX) CONTAINER you can heat the
working surface of your MPS P or MPS P I to allow you to place and align your tissue
sample while the paraffin keeps liquid. Even the temperature can be influenced in the
Main Menu.
You only have to go to the Main Menu by pressing and go down to the line Surface.
As you adjusted the tank settings you are able to set the working conditions to fit your
specific needs.
The function surface heating can be switched on and off manually and by the timer, the
temperature can be regulated in single degree steps.
7.9 COOLED WORKING AREA (MPS P and MPS P I module)
If the cooling element is switched on, the inbuilt cooling fan
is running. The lower and rear airing slots should never be
covered.
The actual temperature of the cooled working area may
vary dependent on the temperature set for the heated
working area and the ambient temperature.
Your new device has a cooling spot which provides a lowered temperature to harden the
liquid paraffin earlier than waiting for hardening with your local air temperature.
To switch the cooling spot on and off you only have to push . For the MPS P you will
see the status of the cooling spot on the standard screen in the last line.
7.10ILLUMINATED WORKING AREA (MPS P and MPS P I module)
For optimized visibility of your work there is a light included in the MPS P and MPS P I
device which you can switch on and off with . Additionally, you can adjust the light
module in the front by turning the black tube as shown in the picture below.

7.12MAGNIFIER (MPS P and MPS P I module)
Each device is equipped with a magnifier
that can easily be turned to the right and left if
required.
The magnifier will keep its orientation even if
turned away temporarily.

20/28 Manual_MPS_2021-10-022.00_EN.docx
7.13 PARAFFIN TRIMMER (MPS P and MPS P I module)
The integrated paraffin trimmer makes efficient
removal of excess paraffin from each cassette.
As a result, the risk of a not adequately clamped
cassette in the cassette clamp is significantly
reduced.
Due to the generous design of the paraffin
trimmer in the heated work surface, the paraffin
melts and can thus immediately drain through
the drainage into the paraffin waste tray located
under the work surface.
7.14 PARAFFIN COLLECTION TRAY
(MPS P and
MPS P I module)
The paraffin from the paraffin waste tray should
not be reused.
To empty the tray, pull it out completely. The
paraffin waste tray should be cleaned daily.
7.15 HEATED FORCEPS (MPS P and MPS P I module) [if device is equipped with this accessory]
The device can also be equipped with electrically
heated forceps. The forceps will be activated by
plugging into the connection for heated forceps at
the front of the paraffin wax dispenser (MPS P and
MPS P I module).
The heated forceps tip allows a more precise
orientation of the dehydrated tissue. As soon as
the work is finished, insert the tips into the forceps
holder. This is drilled through so that the melting
paraffin drains through the drainage system, the
working surface into the paraffin waste tray. This
ensures a clean, tack-free and non-stick forceps
tip.
