  • Working temperature 4 – 60 C
  • Peltier controlled heating/cooling
  • Maintain relative humidity at 100%
  • Touch screen control and setup
  • Automated shutter control allows smooth, instant injection of the sample grid into the coolant. A lift for the container brings the coolant close to the shutter to ensure optimal vitrification
