For details on operation, see the corresponding chapter in the main
chapter “Operation”.
INFORMATION
Depending on the specifications defined by the user, the pO
2
sensor is calibrated either before the vessel is filled with medium
or afterwards, in the prepared medium.
For more details on the calibration refer to main chapter “Opera-
tion”, chapter “Calibrating the pO
2
Sensor”.
9.2 Sampling
Samples are taken from the culture vessel to gain material for of-
fline analysis.
INFORMATION
Using SAMPLE NOW on the operating panel, the sampling can
be logged in the electronic logbook and assigned a sample ID.
For more details, see main chapter “Operation”.
The method of sampling can vary due to the different analyses car-
ried out by the operator.
The sampling procedure using the standard sampling system, Su-
per Safe Sampler, is described below.
Before starting, observe the following:
WARNING
Culture solution could emerge from the vessel if the sample
valve mechanically fails. This could lead to serious health risks
in the event of applications with pathogenic organisms.
– When working with pathogenic organisms, always addition-
ally clamp off the sampling hose with a metal (!) clamp.
– Only remove the clamp when sampling.
– Reattach the clamp before removing the syringe from the
sample valve.
