Instructions for Use V 2.5 RevF – 09/2014

Safety instructions - working with the instrument

Paraffin is flammable and should therefore be handled with due care. Do not use sharp tools to
remove solidified paraffin from the work areas, as this may destroy the coating on the surface.
Use the plastic spatula supplied with the instrument.
During operation, the paraffin reservoir, embedding mold tray, cassette tray, work area as well
as the forceps holder are hot.
Risk of burning!
Do not store any combustible and flammable substances near the instrument. There is a fire
hazard if work with an exposed flame (e.g. Bunsen burner) is carried out in the direct vicinity
of the instrument (solvent vapors). Therefore, keep all ignition sources at least 2 meters away
from the instrument!

Hazards - servicing and cleaning

Switch off the instrument each time before servicing and pull out the power plug.
When using cleaners, please comply with the safety instructions of the manufacturer and the

Paraffin reservoir (1)

The paraffin reservoir has a capacity of approx.
3 liters. The paraffin temperature can be set be­tween 55 °C and 70 °C in 5 K increments. The lid
should always be in place otherwise the adjusted
temperature cannot be maintained.

An overtemperature cutout is provided to prevent
overheating the paraffin if temperature control
fails.
A built-in filtering screen prevents any particles
contained in the paraffin from getting in the par­affin block.

Recycled paraffin may NOT be used in
the Leica EG1150 H due to the danger
of contamination.

Dispenser (2)

The dispenser is heated separately. The tem­perature setting of the dispenser and paraffin
reservoir is coupled.
The quantity of paraffin released from the filler
tube (14) can be adjusted continuously with the
metering screw (11).
The dispenser handle (12) is used for manually
operating the paraffin flow. It is provided with
a pressure clip (13). The pressure clip is height­adjustable and can be shifted to the side (left or
right) depending whether the dispenser handle is
released with the mold or the finger .
The dispenser handle can be operated by simply
pushing the mold (or the finger) against the pres­sure clip. Slightly pushing the handle backwards
will open the dispenser valve . Once released,
the handle flips back in the original position and
the valve shuts.

5. Operation

Work top (3)

The temperature of the work top can be adjust­ed between 55 °C and 70 °C in 5 K increments.
This includes the embedding area, forceps
holder (5) and the cooling spot (4).
The working area has a groove around it and
several drain holes (15), through which excess

5

paraffin rapidly drains.

3

4

3

Cooling spot (4)

The cooling spot is an integral part of the work
area. Its position directly in front of the em-

15

bedding area enables convenient working in
ergonomically most favorable conditions.
To orientate the samples, the mold is filled
about one third with liquid paraffin. The liquid
paraffin begins to solidify rapidly on the cool­ing spot.

4

While the paraffin is semi-liquid, the sample
can be oriented as required. Finally, the mold
can rapidly be filled up with paraffin.

While orienting the tissue, the paraf­fin should not become too solid, as
this may cause different phases in

5

the finished block, including fissures
inside, as a result of which the block
may break during sectioning.

Forceps holder (5)

The removable forceps holder under the dis­penser can accommodate up to 6 forceps.

Fig. 11

The forceps holder is constantly heated
to approximately 70 °C.
Risk of burning!

8

The paraffin collection tray must be
emptied daily. To prevent contami­nation, do not reuse paraffin collect­ed in this tray.
If the instrument is operated without
the paraffin collection trays there is
risk of burning.

Embedding mold tray and cassette tray (16)

Depending on the preferred working direc­tion, the two heated instrument trays (6, 7)
can be used for embedding molds or cas­settes. The temperature is adjustable between
55 °C and 70 °C.
A removable tray (16) for cassettes or embed­ding molds can be placed in each instrument

17

16

tray.
Each receptacle can hold approx. 100 cas­settes or approx. 50 molds.
A lid (17) is provided for each of the trays (16)
to prevent loss of heat and contamination in-

Fig. 12

side the tray. For easy access, the lid can be
slid back and folded up.

22

When working with half-open lids (17),
raise the temperature one level to ensure
that the paraffin remains molten.

Only operate the cassette and em­bedding mold tray and paraffin res­ervoir with lid; otherwise the set
temperature cannot be maintained.

The foot switch (22) actuates the mag­net valve of the dispenser.
It must be connected as described in

Chapter 4.6.

The plug of the foot switch
MUST be screwed to the
socket. Otherwise hot paraf­fin can escape, even if the
switch is not activated.

Pressing the foot switch opens the
valve, releasing it closes it. This keeps
the operator's hands free to work with
the instrument.
The flow volume can be adjusted with
the metering screw (11).
The dispenser handle (12) is not re­quired when using the foot switch and
can be folded upwards.

Proceed as follows:

• Setthemeteringscrew(11) to mini-
mum.

• Carefully fold the dispenserhandle

(12) back/up with your thumb and
index finger.

an extended period.

• The heaters become active and the LEDs indicate the values last set.
The target value LEDs for the heating areas (1, 3, and 4 in Fig. 18) flash

quickly for the duration of the heating phase (cf. "Display of the heating
intervals").

Fig. 16

The LED for the paraffin reservoir (2 in Fig. 18) flashes in 1-second inter-

vals and thereby indicates the intensified heating of the paraffin reser­voir (for 4 hours).

If temperature settings are modified during the heating phase, the in-

strument will store the new settings and the heating phase will then
correspondingly take longer.

• Fill the paraffin reservoir with paraffin.

Prior to leaving the factory, the Leica EG1150 H is tested thoroughly under laboratory condi­tions. For this reason, you will find a small quantity of clean, hardened paraffin. You can work
with this paraffin without any problem.

Advance times

Display

Enhanced mode

5. Operation

To ensure that the instrument is ready (all working temperatures reached)
at the programmed start time, the various sections are activated in advance
as follows:

Paraffin tank: Heating starts 4 hours before working time begins.
Work top: Heating starts 4 hours before working time begins.
Dispenser tube: Heating starts 1 hour before working time begins.
Cooling spot: Cooling starts 1 hour before working time begins.

During the heating phase, the display reads - - : - - ; the colon flashes in
intervals of seconds.
The advance times cannot be modified.

A large amount of heat is needed for melting paraffin. This is only account­ed for in standby mode for a respective preliminary time. In the operating
mode, the paraffin reservoir is heated just enough to maintain the paraffin
at the selected temperature. Therefore the melting process can be sped
up by increasing the heat supply (enhanced mode) whenever necessary
(e.g. when solid paraffin has to be added to the reservoir when working in
shifts). The paraffin reservoir is then heated for a period of four hours to a
higher temperature (enhanced mode).

Press simultaneously

Leica EG1150 H – Paraffin Embedding Station

Fig. 23

To activate the enhanced mode, push and hold
the and buttons simultaneously.
The brief lighting up of all four target value
LEDs of the paraffin reservoir confirms that the
on-demand heater has been activated. In other
words, the buttons have to be held until all 4 LEDs
light up.
The selected set value LED flashes while en­hanced mode is enabled.
The enhanced mode can be switched off at any
time by pressing and holding the same key com­bination. Deactivation of the on-demand heater
is also confirmed by all four target value LEDs
lighting up.

6. Maintenance and Cleaning

6.1 Cleaning the instrument

Do not use xylene for cleaning. Xylene vapors are heavier than air and can ignite at a consider­able distance from the source of heat.
A fire hazard exists!
To avoid scratching the surface of the instrument only the plastic spatula that is supplied with
it should be used for cleaning – on no account use metal tools!

Work surfaces

• Allcommonlaboratorycleaningproductssuitablefortheremovalofparaffin(e.g.Paraguard

or xylene substitutes) can be used to clean the work area.

• Avoidprolongedcontactoforganicsolventsonthesurfaceoftheinstrument.
