
Type: Easyferm Plus ARC

Manufacturer: HAMILTON
INFORMATION
The matching pH sensor is included in the standard package.
These pH sensors are pre-configured by the equipment manu-
facturer, INFORS HT. Replacement sensors must be configured
before use.
For details on the technical data, maintenance and storage require-
ments for the pH sensors, see the separate documentation pro-
vided by the sensor manufacturer. Read and follow the instruc-
tions.
Calibration of the pH sensor is always carried out
BEFORE auto-
claving. This is done on the operating panel. For more details on
this procedure refer to the main chapter “Operation”, chapter “Cali-
brating the pH Sensor”.
INFORMATION
If the pH sensor has already been calibrated before connection
to the system, the bioreactor will use this data and calibration on
the operating panel is no longer necessary.
For culture vessels with nominal widths of 90 and 145, pH sensors
can be mounted directly into 12 mm/Pg13.5 ports. For culture ves-
sels with a nominal width of 115, an electrode holder is used.
For more details on the electrode holder, see the “Accessories”
section, sub-section “Electrode Holder”.

Control
The oxygen saturation of the (culture) medium is measured by the
pO
2
sensor, and can be adjusted as follows:
Increasing the pO
2
The content of the oxygen dissolved in the medium (pO
2
) can be
increased using the following methods:

Increasing the stirrer speed

Increasing the gas volume flow rate (air and/or oxygen)

Increasing the oxygen content in the Gasmix.
