Changing Tubes of the Exhaust
Collector
If a glass part of the exhaust collector has broken, you
need not replace the exhaust collector as a whole. The
iner parts of the exhaust collector consist of
the suction vessels that reach into the sample ves-
sels with their long tubes (carrying the PTFEstoppers
on their ends); with
short Viton tube cuttings they are connected to the
collecting tube. And on the nozzle of this collecting
tube there is the
suction hose that connects the exhaust collector to
the scrubber.
Danger of injury in case of breakage of
glass! Always adhere to your professional
association's regulations when handling
glass parts!
Opening the Housing of the Exhaust Collector
Undo the four screws on the rear panel of the
housing.
Undo the four screws on the roof of the housing.
Take the panel off that forms the rear and the roof of
the housing.
On top of the suction vessels you see the two crossbars
that are fixing them. They had held the roof panel by
the four screws that you have just unscrewed. They are
themselves fastened to the intermediate bottom by four
long screws.
Unscrew the long screws that hold the crossbars to
the intermediate bottom.
Take these two crossbars off the suction vessels.
The suction vessels, with their long suction nozzles, go
through borings of an intermediate bottom. In order to
take them out you must first take the PTFE stoppers off
the suction nozzles.
