  • Lowest possible temperature of the Peltier element: -45 C
  • Lowest possible temperature of the Peltier element together with quick-freeze shelf: below -60 C
  • Running time of the Peltier element:15minutes
  • Maximum Specimen Size: 35mmx35mm
  • Specimen Vertical Stroke: 60mm
  • Specimen Horizontal Stroke: 20mm
  • Electric Coarse Feed: rapid 7mm/s; slow 0.35mm/s
  • The section thickness is adjusted in a range of 1μm to100μm

            1μm-20μm     increments 1μm;

            20μm 40μm    increments 2μm;

            40μm-100μm    increments 5μm;

  • Trim Section Thickness Feed: adjusted in the range of 10μm to 400μm

            10μm 50μm     increments 5μm;

            50μm-100μm    increments 10μm;

            100μm-400μm   increments 50μm;

  • Specimen Retraction Distance: adjustable in a range of 0 ~ 80μm, in 5μm increments
  • Working Voltage: AC220V+/-10%50Hz (standard model); AC110V+/-10%60Hz
  • Power: 600W
  • Dimensions: 650x805x1160mm(WxDxH)
  • Net Weight: 115kg


  • This model has an ergonomic design and is manufactured using numerically-controlled machine tools;
  • A specimen retraction function protects the specimen from blade damage;
  • A trim button allows for easy switching between trim and sectioning mode;
  • Includes a counting function for the number of sections and the total thickness;
  • The cryogenic refrigeration system utilizes a forced cooling structure. The refrigeration chamber, freezing shelf, blade holder, and specimen holder are cooled independently by a German double compressor to enhance cooling performance and increase cooling speed.
  • Imported R404A non-CFC refrigerants that are environment-friendly;
  • Achieves the desirable sectioning temperature within 20 minutes after turning on the unit when using the fast cooling mode;
  • UV option enables surface disinfection of harmful bacteria, viruses, and spores by using35 min after each use; It also has low-voltage DC shadowless lamp;
  • Semiconductor cooling function can be turned on and off;
  • Hearable and removable glass door;
  • Two defrosting modes: time defrosting and manual defrosting;
  • Microtome is outside of the refrigeration chamber to avoid the effect of heat-expansion and cold-contraction, thus minimizing the need for maintenance;
  • User-friendly intelligent operational interface is easy to learn and operate;
  • LCD screen displays the number of sections and the total thickness, section thickness, specimen retraction value, temperature setting, date, time, temperature and on/off timer are all included on the main display;
  • Auto sleep function results in longer compressor life: the cryo-chamber temperature automatically stays in a range of -1 to -9 C under the sleep mode, and returns to the sectioning temperature within 15 minutes after canceling the sleep mode;
  • Keyboard locking function to avoid accident maloperation;
  • A mechanical hand-wheel lock ensure safe chamber access, 16 position for locking;
  • The red bar on the blade holder covers the whole length of blade to protect the user and the push bar enables easy changing of the blade;
  • A large-size quick-freezing shelf allows for the preparation of 26specimens at the same time; Two holes for semiconductor refrigeration;
  • It has cleaning device, easy help customer to clean the unit;
  • Specimen Orientation: XY -12; Z -360 adjustable at any orientations to ensure precise placement;
  • Self-detection function for the temperature senor, can help to warn the failure on temperature senor.
