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.

6.7 Freezer pack

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
