An opening for ventilation of the interior is located in the top centre
of the rear of the housing. The purpose of ventilation is to supply
bacterial cultures with oxygen from the air.
The opening with a diameter of 22 mm is covered by a metal plate
with a plug and O-ring (1). The plate can be mounted in two different
ways:
If the plug (1) is facing inwards and the folded parts of the plate (2)
■
are facing outwards, the plate will seal tightly.
If the plug (1) is facing outwards and the folded parts of the plate
■
(2) are facing towards the device, this results in a ventilation slot.
The device is always delivered with an open ven-
tilation opening. If increased gas consumption is
detected when using the optional CO
ventilation opening can be closed. Note that closing
2
the ventilation opening can lead to a lack of oxygen
to the culture and thus to low growth.
The device features two LED spots to illuminate the incubation
chamber. These are located in the door area on the inside of the
housing.
The working light is switched on automatically as soon as a key is
pressed or the door is opened. After 2 minutes without input or
2 minutes after closing the door, the working light switches off again
automatically.
The Settings menu (OPTION key) can be used to completely deacti-
vate the working light if necessary.
Different versions of the incubator shaker are available with different
