When using such disinfectants, avoid open flames or exposure
to excessive heat during the entire disinfection process!
• Use such disinfectants only in adequately ventilated rooms.
• After the disinfectant has been allowed to react, wipe the
cleaned device components thoroughly dry!
• Observe safety regulations to avoid fire and/or explosion
hazard caused by alcohol-containing disinfectants!
Water supply:
The water tray of the work space can hold up to 3.0 l of proces-
sed water. When the running operation, always keep a suf-
ficient quantity of processed water of the following quality
available:
• demineralized and distilled or autoclaved for sterilization,
or
• completely deionized and distilled or autoclaved for sterili-
zation.
• When the water level falls below the lower limit, refill
water!
1.6 Intended purpose of the device
1.6.1 Correct use
The CO
2
incubator is a laboratory device for preparing and cultivating cell
and tissue cultures. The device allows the simulation of the special physio-
logical ambient conditions for these cultures due to the exact control of:
Control features
• temperature,
• CO
2
content,
• an increased relative humidity.
The device has been designed for installation and operation in the follo-
wing fields of application:
Fields of application
• Laboratories for cytobiological and biotechnological experiments of
safety levels L1, L2, and L3.
• Medical-microbiological laboratories in accordance with DIN 58 956.
• Laboratories in the central area of clinics and hospitals.
Gas supply
The CO
2
required for the incubator is supplied to the device from a separate
gas supply system, either from gas cylinders or from a central pressurized
gas container.
The layout of the gas supply system must ensure that the operating pres-
sure of the gas supply lines can be set to a range between 0.8 bar (min.) to
1 bar (max.) and that the pressure cannot be changed.
Depending on the capability of the gas supply system, several devices may
be connected to one gas cylinder.
The CO
2
incubator is suited for continuous operation.
1.6.2 Incorrect use
Safety levels
Do not use cell or tissue cultures in the device that are not in accordance
with the regulations of safety levels L1, L2, and L3.
