CO
2
Control
The optional CO
2
control makes it possible to enrich the atmosphere
in the incubation chamber by 0 to 20 % CO
2
. The CO
2
control option
is particularly suited to cultivation of mammalian cells and algae be-
cause the CO
2
ensures that the pH value in the culture solution is sta-
ble.
CAUTION
During normal operation, small amounts of CO
2
are constantly dis-
sipated into the environment. Leaking CO
2
can lead to discomfort,
loss of consciousness or even death by suffocation, especially in
small rooms.
–
The operator is obliged to install a monitoring system which
permanently monitors and analyses the CO
2
concentration in
the room.
–
If you are using the CO
2
control, only operate the device in
well-ventilated areas.
–
Comply with local health and safety regulations and regula-
tions regarding the use of CO
2
and its limits.
–
Regularly check the gas pipelines for leaks.
INFORMATION
Opening the ventilation opening at the back of the device can lead
to significantly higher gas consumption. We therefore recommend
leaving the ventilation opening closed when using the CO
2
control
option.
4.4.1
Setup and Function
CO
2
supply is controlled using a controlled valve. Inflow of CO
2
must
be ensured using external supply where the pressure can be regu-
lated. On the right side of the casing, there is a hose nozzle for a
hose with a diameter of 3 to 4 mm to connect the supply.
