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

- 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
