pH and DO sensors
The Cellbag bioreactor may be equipped with optical sensors for monitoring pH and
dissolved oxygen (DO). The sensors are light sensitive and should be protected from ex-
cessive light. The sensors are located in the center of a sensor port on the Cellbag
bioreactor and must be coupled to a sensor adapter, see table below.
DescriptionPart
The sensor port is located on the underside of the Cellbag bioreactor.
The actual sensor (white/yellow for pH, pink/black for DO is located
in the center (1) of the sensor port, see image below.

port
The sensor adapter is attached to the sensor port by the four pins (2).
The sensor adapter is located at one end of an optical fiber cable.
The optical lens of the fiber cable is located in the center of the sensor
adapter. The fiber cable is connected to a sensor reader in the CBCU.
The fiber cable is connected to the pH or DO port on the CBCU front
panel.
