  Initial Installation
To assemble, proceed as follows:
t Insert the new membrane into the lower part 
of the dialysis probe. Ensure that the white 
side of the membrane points in the direction 
of the dialysis probe (in contact with the 
buffer) and the colored side of the membrane 
points in the direction of the probe lunette 
(incontact with the medium).
t Mount the probe lunette on the upper part of 
the dialysis probe.
t Attach the dialysis probe to the lower part of 
the dialysis probe with the supplied TORX key.
6.2.2  Mounting the Membrane for 
MeasuringMethanol and Ethanol in the 
Dialysis Probe
This special probe lunette must be used to 
measure methanol and ethanol. This is the only 
way to prevent obstructions at the membrane 
lunette and to avoid incorrect readings or 
leakages in the tubing set.
t Use the special probe lunette with identifier 
“-0.2”.
