Introduction

During routine work in histopathology laboratory, excessive paraffin and other impurities buildup on work tables and instruments is everyday occurrence, especially on tissue processors that use liquid paraffin, and on microtome that processes paraffin blocks. It is important to keep microtome clean and to regularly remove excessive paraffin, as well as to keep it functional. Beside cleaning, for keeping microtome working optimally it is essential to lubricate the moving parts using a special Microtome oil. It is recommended to lubricate the moving parts at least once a month, and even more frequently if possible.
