Safety devices S
The device is equipped with the following safety devices:
• A door switch interrupts the CO
opened.
• When operated with the gas monitoring option, a gas monitor switches the gas supply to a full gas
tank.
• An overtemperature protection protects the samples from harmful overheating in case of failures.
• A pressure compensation opening ensures pressure compensation in the device workspace.
• The alarm relay circuit uses audible and visual alarms to indicate errors during operation.
Workspace atmosphere
In the workspace of the incubator, the particular physiological ambient conditions for the preparation
and cultivation of cell and tissue cultures are simulated. The workspace atmosphere is determined by
the following factors:
• Temperature
• Relative humidity
• CO
• O
2
Temperature:
To ensure undisturbed operation, the temperature in the operating room must be at least 18 °C and the
incubation temperature must exceed this temperature by at least 3 °C.
The heating system controls the incubation temperature from this temperature threshold up to 55 °C.
By heating the inner compartment with independent heater circuits and by separately heating the outer
door in addition, condensation is prevented on the sidewalls and the ceiling of the workspace and the
glass door or gas-tight screen.
