BOC Histotechnology- Processing During microtome, it is noted that many of the tissues are very hard and shrunken. Of the following, the most likely explanation for this problem is that the: - correct answers INFILTRATING PARAFFIN IS TOO HOT. When tissue is processed in paraffin wax that is more than 2 degrees Celsius to 4 degrees Celsius above the melting point, the tissue becomes hard and shrunken. Decalcification of small specimens can be achieved by fixation in: - correct answers ZENK...
