6.7 Tray
The freezer pack consists of the freezer plate (98)
and the insulation jacket (99). It is for cooling (or
keeping cold) paraffin specimens. Up to 35 stan-
dard cassettes can be cooled at the same time.
The specimens require approx. 20 min. for being
cooled from room temperature (approx. 20 °C) to
"sectioning temperature."
The cooling performance depends on the ambient
temperature and the volume of the specimens
being cooled.
The insulation jacket can be placed on the hood
of the microtome in the same manner as the tray,
or it can be placed next to the instrument.
The tray is mounted on the hood of the microtome
so that the small feet on the underside fit into the
cutouts on the hood.
It is for storage of the utensils used during sec-
tioning as well as the sectioned specimens.
When using the freezer pack on the
instrument the tray (Fig. 44) must be
removed.
• Remove the freezer plate from the insulation
jacket and place it in a deep freezer, ideally
overnight (but for at least six hours) at approx.
-23 °C.
• Reassemble the freezer plate and insulation
jacket and place them on the bench or the
instrument.
