6.6 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 standard 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.
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.
The tray is mounted on the hood of the micro-
tome so that the small feet on the underside fit
into the cutouts on the hood.
It is for storage of the utensils used during
sectioning as well as the sectioned specimens.
