The FS800 frozen microtome is a semi-automatic microtome whose box and sample head can be refrigerated independently. It is used clinically for rapid pathological diagnosis during surgery and scientific research.





  • Smart thermostat: 1. The compressor adopts variable frequency temperature control mode, which has a    small temperature fluctuation range and more accurate temperature control. A stable low-temperature environment is conducive to cutting high-quality slices. 2. Active cooling of the sample head realizes temperature control of the sample head through multiple methods such as compressor, refrigerant, and semiconductor refrigeration, creating optimal slicing conditions to meet the needs of various types of samples.
  • Precise injection: The top-level cross guide rail and precision screw, together with the five-phase high-resolution sampling motor and the horizontal sampling slider made of aviation aluminum, form a high-precision sampling system to ensure the quality of slices.
  • Rapid positioning: Patented visual pointer mark, the angle adjustment data is intuitive and visible, when adjusting the tissue angle of different inclined surfaces, the direction of the sample head can be precisely controlled to avoid waste of tissue samples.
  • Low-Temperature UV Disinfection System: The equipment is equipped with an ozone-free UV disinfection system to reduce the risk of contamination from infectious materials. UV disinfection can be performed at any time and at any temperature.
  • Automatic sleep and wake up: It will automatically go to sleep according to the set time. In sleep mode, it can be scheduled to wake up automatically without manual operation. It can be used immediately when needed.
  • Waste management system: Realize alarm management for waste liquid bottles that are not in place and full bottles overflowing to prevent waste liquid from flowing out and contaminating the ground.
