Cooling Processes
Specimen and blade holder cooling
Integrated refrigeration systems allow the blade holder to be cooled to -35°C and the specimen head to be
cooled to -50°C. Specimen stations are located on the left side inside the Cryochamber.
These specimen stations passively cool specimens to a temperature of -30°C and can be used as a staging
area.
The temperature range of the specimen head is adjustable b10°C and -50°C.
The instrument is also equipped with an active Cryobar.
The Cryobar area actively cools down to -60°C.
Note
Use the heat extractor to accelerate the freezing of the specimen.
