Minux® FS800A Cryostats

With a fully automated, user-friendly operation system, FS800A freeze microtome gives you the confidence to consistently produce reproducible, thin, serial frozen sections of maximum quality. It’s your ideal choice for fast, accurate, and fatigue-free frozen sectioning.

Available Types:
FS800A Auto: Cryostat with motorized sectioning to improve reproducibility.
FS800A Max: Fully automatic cryostat with vacuum cleaning system for whole function.



  • Four automatic slicing modes can meet the needs of different slicing tissue scenes.
  • Cutting window function ensures the quality as well as improve the efficiency.


  • Stable temperature: the advanced temperature control system, compressor and cooling system perfectly guarantee temperature stability.
  • high-precision cross rail and screw, five-phase high-resolution sampling motor and horizontal sampling slider made of aviation aluminum, form a precise sampling system to ensure stable slice quality.


  • UVC disinfection: adopting advanced low-temperature UVC disinfection technology to effectively kill bacteria and viruses, disinfecting the inner surface and the air of the cabinet to reduce the risk of contamination by infectious materials.
  • Waste liquid management system: waste liquid volume will be displayed on the touch screen. Full bottle alarm to prevent waste liquid from flowing out and contaminating the ground.


  • Efficient operation: boasting a colorful touch-sensitive screen. Integrating coarse sample feeding, trimming and section switching, and slice parameter adjustment with a joystick to constitute an efficient operating system.
  • Quick positioning: precise positioning system with ±8°visual pointer make it easy to adjust the specimen clamp to the target angle, reducing trimming and sample waste.
  • Automatic sleep and wake-up: save energy, simplify manual operation and reduce waiting time.
  • Sample installation and marking: buckle design, convenient installation and firm fixation. The unique label design of specimen discs makes it easy to record and identify each sample to prevent confusion.
  • Efficient and thorough defrosting: automatic and thorough defrosting for cryo-chamber, specimen head, quick-freeze shelf. Manual defrost is also available, allowing operator to defrost partly to improve efficiency.
