8.0 MEASUREMENT AND CONTROL OF TISSUE TEMPERATURE
8.1 The optimum cutting temperature for a given type of tissue is best determined by experiment.
Several Physitemp thermometers are available for such measurements; they also have many other laboratory
uses. There are several sizes of needle probe, which can be inserted in the specimen either before or after
freezing. The BAT-12 thermometer, which has a range from -100
o C to +200 o C, permits the user not only to
find optimum cutting temperature, but to return to it subsequently.
8.2
One of the main advantages of these freezing stages is the ease with which the temperature of
frozen tissue can be varied, simply by adjusting the CURRENT control. The following temperatures have
been found satisfactory:
Tissue Temperature o C
Kidney -15
Brain -18
Liver -18
Thyroid -20
` Skin -30
Keloid -35
Patella -40
9.0 MAINTENANCE, WARRANTY AND SERVICE
9.1 MAINTENANCE. The stage needs no maintenance at all. It may be cleaned as necessary with a
soft cloth, water or detergent. DO NOT IMMERSE IN WATER. Because of expansion and contraction due
to the wide temperature range, it is not possible to completely seal the stage.
