Cleaning the reactor interior
5. Cleaning the reactor interior
Sometimes volatiles are set free during the measurement, e.g. softeners and waxes. These
substances will condense on the cooler inner surfaces of the reactor depending on condensing
temperature and heating temperature. It may be necessary to clean the reactor sometimes, if
visible layers occur.
Important: Check the O-Ring regularly for
deposits!
To do this, switch off the power, open the
reactor and take out reagent tray and sample
tray.
Use a paper tissue, wetted with pure alcohol
(moist but not dripping) and wipe over the
soiled spots. Especially the reactor- surface
opposite to the sample tray can be cleaned
this way.
The pipes are cleaned best with a test-tube
brush (see picture). Put in the sample tray to
avoid contamination of the heating plate.
Afterwards, check the O-ring. No dirt particles
may remain on the sealing.
