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.
The freezer pack consists of the cooling plate
(98) and the insulation jacket (99). It serves for
cooling paraffin specimens (or keeping them
cool, resp.). Up to 35 standard cassettes can be
cooled at the same time. The specimens require
approx. 20 min. for being cooled from room tem-
perature (approx. 20 °C) to "sectioning tempera-
ture".
The cooling performance depends on the ambi-
ent temperature and the volume of the speci-
mens 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
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 ap-
prox. -23 °C.
• Reassemble the freezer plate and insulation
jacket and place them on the bench or the
