8.1.20 Preparing the Gassing Hose Line on the Basic Unit
An appropriate hose line must be prepared on the basic unit in or-
der to connect the sparger to the gassing after autoclaving.
Proceed as follows:
Procedure
1.
Cut a piece of thick walled silicone hose (Ø 5 x 8 mm, in the
starter kit).
Choose its length so that the hose connection between
sparger and gas supply on the basic unit does not have any
tension or kinks.
2.
Fit the hose to the hose nozzle of the gassing unit(s) on the
basic unit.
3.
Secure the hose with cable ties.
8.1.21 Calibrating the Pumps
Not calibrated pumps show the duration in seconds and the num-
ber of rotations. If the delivered volume (in mL) shall be indicated
instead, the pumps must be calibrated before autoclaving.
A detailed description of how to calibrate the pumps can be found
in the separate operating manual of the touch screen software.
