Which type of microtome is most commonly used in routine histopathology laboratories for sectioning paraffin-embedded blocks?
Show answer and explanation
Correct answer: Rotary microtome
The rotary microtome is the standard for routine work because it allows for the production of serial sections and provides excellent stability. It operates by converting the circular motion of a handwheel into the vertical motion of the block holder.
