• Screw heat extractor into quick-freeze
shelf.
• Place it directly on the specimen surface.
After approx. 30 seconds (depending on
tissue type and specimen size) the speci-
men is entirely frozen.
To prevent unnecessary distortion of
the specimen during contact freez-
ing, the weight of the heat extractor
can be balanced.
• For that purpose, loosen screw (2) and ad-
just knob (1) upwards or downward.
• Retighten screw (2) to fix knob (1) in the ap-
propriate position.
