9.2.11 SOFT TIME-BASED FREEZING and subsequent storage
In order to select a SOFT time-based freezing cycle, you just need to make sure not to insert the
core probe
The time-based freezing and storage cycle consists in three phases:
► 1st phase: Soft freezing cycle (60% of the whole duration of the cycle; Room temp. setpoint 0°C)
► 2nd phase: Hard Freezing cycle (40% of the whole duration of the cycle; Room temp. setpoint -40°C)
► 3nd phase: Storage (Room temp. setpoint -20°C)
After completing a phase, the blast chiller automatically switches to the next one.
- Make sure the core probe is disabled.
- Make sure the blast chiller is in “ON” mode, that the keyboard is not locked (chapter 11) and that
no procedures are being carried out.
