12.2 Thermal block
The thermal block
(8)
facilitates the removal of the fro-
zen specimen from the specimen disc.
Keep the thermal block outside the cryocham-
ber at room temperature.
•
Place the cap
(9)
on the required side, so that the
appropriate location hole for the specimen disc is
visible.
•
Insert the shaft
(6)
of the specimen disc
(5)
in the
appropriate location hole
(7)
at the top or bottom of
the thermal block.
•
After about 20 seconds, the frozen specimen can
be removed from the specimen disc with forceps.
•
If the cap is too loose, readjust it with the small
screw
(10)
. Do not overtighten the screw.
•
Once the specimen is removed, take the thermal
block out of the cold cryochamber.
12.1.2 Stat ionary heat extractor
•
Screw the heat extractor into the hole on the quick-
freeze shelf. It can reach three specimen discs.
•
Lower the heat extractor cylinder on the tissue sur-
face. After approximately 30 seconds, the specimen
will be entirely frozen.
To prevent unnecessary distortion of the
specimen during contact freezing, the weight
of the heat extractor can be balanced.
•
To balance the weight of the cylinder, loosen screw
(2)
and move the knob
(1)
up or down as required.
•
Retighten screw
(2)
to fix the knob
(1)
in the appro-
priate position.
12.1 Heat extractors
Specimen freezing on the quick-freeze shelf can be ac-
celerated by the additional use of a heat extractor.
12.1.1 Mobile heat extractor
•
Store the heat extractor in the cryochamber.
•
Place it on the specimen surface to accelerate
freezing.
•
Remove it once the specimen is entirely frozen.
