Minux® FS800 Cryostats Semi-Automatic

FS800 Cryostat, also called freeze microtome, is a semiautomatic type designed to consistently produce high quality frozen sections of maximum quality. Featured superior capability, it is able to cut tissues at low temperatures (as low as -35 °C) quickly. Even at open-window opeation model, the Cutting-Edge Cooling Technology achieves less than 2°C of temperature fluctuations in 3 hours.

Available Types:

  • UV: for large specimen numbers and varying specimen types with UVC for increased user safety.
  • Specimen: Standard type with individually controlled temperature settings on both the cabinet and the object specimen holder.


“With excellent low temperature stability, RWD cryostat produces high quality section consistently.”

——Capital Medical University


“RWD Cryostats can maintain a stable temperature and produce high-quality sections even after slicing for more than half an hour with the camber opening all the time.”

——Shenzhen Institute of Advanced Technology, CAS


“Stable temperature, high quality sections without curling”

——Kunming Institute of Zoology, CAS

  • Applications
1. Stable

1.1 Stable temperature:
the advanced temperature control system, compressor and cooling system perfectly guarantee temperature stability.
1.2 Stable slice quality: 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.

2. Safe

2.1 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.
2.2 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

3. Efficient

3.1 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.
3.2 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.
3.3 Automatic sleep and wake-up: save energy, simplify manual operation and reduce waiting

RWD FS800 and FS800A cryostats have been registered and listed by the US FDA (available on the FDA official website) and have been approved for clinical use.
