CytoSAVER is a next-generation solution that does not require liquid nitrogen as a refrigerant, unlike traditional controlled-rate freezers. It is a compact, space-saving, on-demand product that can be used when you only need a power source. The built-in software allows you to perform programmed freezing of animal cells, cord blood, sperm, eggs, etc. at the desired cooling rate.

  • Lightweight and compact design, can be used inside a clean bench or isolator. It is also ideal for use in clean rooms and CPC/CPF.
  • The cooling plate can be set without tools, which prevents temperature rise during sample transfer.
  • The cooling area has a torque-hinged cover for easy opening and closing.
  • The built-in heater allows the cooling plate to return to ambient temperature after the freezing process is complete.
  • You can set and register your desired freezing pattern from the built-in touch panel.
  • Plate/sample temperature can be measured and recorded, and processing results can be output in PDF and CSV format.
  • Users can be managed with the user login function, and there are three levels of authority settings (FZ-2200 only).
