8.1.17 Preparing the Sensors

22 January 2019
Before Fermentation/Cultivation
If applicable, i.e. temperature control system with electrical heater
pad and cold finger is present (system for single walled culture
vessels), the cold finger must be mounted in its appropriate port in
the vessel top plate.
Proceed as follows:
Mounting in Ø 12 mm / Pg13.5 port
1. Equip the 12 mm / Pg13.5 port with an O-ring.
2.
Insert the cold finger into the port and tighten it by hand.
3. Adjust its mounting depth as desired.
Mounting in Ø 19 mm port
1. Equip the 19 mm port with a threaded adapter.
2. Insert the cold finger with fixed O-ring into the threaded
adapter and tighten it with by hand.
The mechanical seal must be lubricated at any time.
Therefore it must be ensured, that the silicone hose on the bottom
of the drive hub is always entirely filled with glycerine. Top it up, if
necessary.
For details refer to chapter „Cleaning and Maintenance", „Lubricat-
ing the Mechanical Seal".
ATTENTION
Risk of loss of property due to the mechanical seal running dry!
A mechanical seal, which has not been adequately lubricated, is
destroyed when running dry.
All sensors that come into contact with the medium are mounted
before autoclaving and are sterilised together with the culture ves-
sel.
Note the following about all sensors:
Mount all sensors by hand – do not use any tools!
