Microm HM550

The HM 550 series is a uniquely progressive concept for use with frozen specimens of all types. User applications define module selection and make even serial sectioning enjoyable. The HM 550 basic instrument offers a chamber temperature down to -35°C. A fine / trim motorized feed system from 1 to 500 µm, automatic approach system, movable chamber illumination and automatic specimen retraction, are some of the many standard features.

 

  • Indication of data such as set and actual temperature, section sum, remaining travel, number of sections, actual time, trim and fine sectioning thicknesses, retraction function 
  • Automatic approach system (ACA) for the exact and safe approach of the specimen towards the knife and/or blade 
  • Electronical handwheel brake – can be locked in any position 
  • Temperature control of the cryo chamber continuously from 0°C to –35°C 
  • Heated sliding window

 

  • Standby and sleep mode for saving energy 
  • Automatic defrosting device with immediate defrosting and additional interruption function 
  • Fast freezing station for the simultaneous freezing-on of 12 specimens (30 mm chucks) 
  • High performance rotary microtome: 
  • Section thicknesses from 1 mm to 100 mm: o 
    • 1 – 10 mm in 1 mm-increments; o 
    • 10 – 20 mm in 2 mm-increments; o 
    • 20 – 100 mm in 5 mmincrements 

 

  • Trimming section thicknesses from 5 mm to 500 mm: o 5 – 10 mm in 5 mm-increments; o 10 – 100 mm in 10 mm-increments; o 100 – 200 mm in 20 mmincrements; o 200 – 500 mm in 50 mm-increments 
  • Specimen retraction that can be turned off 
  • Horizontal feed range: 28 mm 
  • End position indication and automatic turnoff when reaching the front and rear end positions of the horizontal range 
  • Motorized coarse feed and reset movement with three different speed settings 

 

  • Vertical cutting stroke: 60 mm 
  • Max. specimen size: 70 x 55 mm 
  • Specimen can be rotated in Z-axis, 360° and specimen orientation 
  • 0-positioning of the chuck 
  • Continuous specimen temperature control from +10°C to –50°C 
  • Cutting speed from 0 – 250 mm/s can be controlled continuously (motor option)

 

  • Accelerated return travel for fast operation 
  • Cutting window that can be selected (motor option) 
  • Three operating modes: interval, single and continuous stroke (motor option) 
  • Can be activated either via the foot pedal or manually (motor option) 
  • Motor brake and emergency stop switch for safe operation (motor option) 
  • Integrated Vacutome system for stretching cryo sections as well as for the suction of debris (option) 

 

  • Integrated fast freezing device with separate cooling element (Peltier) down to max. –60°C for four specimen (30 mm chucks) (option) 
  •  Dimensions o Wide: 640 mm (w/o handwheel) o Deep: 760 mm o High: 1200 mm 
  • Weight: 125 – 155 kg (depending on the model)
