21 Leica EG1150 H – Paraffin Embedding Station
Work top (3)
The temperature of the work top can be adjust-
ed 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
paraffin rapidly drains.
Cooling spot (4)
The cooling spot is an integral part of the work
area . Its position directly in front of the em-
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 cool-
ing spot.
While the paraffin is semi-liquid, the sample
can be oriented as required. Finally, the mold
can rapidly be filled up with paraffin.

The forceps holder is constantly heated
to approximately 70 °C.
Risk of burning!
While orienting the tissue, the paraf-
fin should not become too solid, as
this may cause different phases in
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 dis-
penser can accommodate up to 6 forceps.
