HM 355S Automatic Microtome from Thermo Scientific

The Thermo Scientific HM 355S automatic rotary microtome is an electronic, motorized rotary microtome that sections safely even the largest specimens with unmatched quality. It is designed for all applications of paraffin and hard specimens in clinical, research, and industrial labs.


  • Excellent for routine paraffin sections and plastic-embedded specimens
  • Provide high-quality sections with less fatigue
  • Unmatched safety, ease-of-use, reliability, and consistency of results
  • NEW - Rock option: specimen head advances by a set amount to trim specimens without turning the handwheel through full turns
  • Menu-driven control panel can be used on either side of instrument
  • Display monitors a range of functions including cutting speed, section count, section thickness, and advance distance
  • Four cutting modes of operation (single, interval, multi and continuous)
  • User-selected cutting window control maximizes throughput by allowing the return stroke to be faster than the optimized cutting stroke
  • Manual and/or foot pedal control. Double tap start activates sectioning motor
  • One-handed zero-orientation head
