2.2 Measuring Chamber
The measuring chamber contains both the sample holder and
the photomultiplier. It can be opened using the black button.
Only in its closed state the measuring chamber is light-tight,
which is a prerequisite for luminescence detection.
Individual test tubes are inserted into the sample holder for
measurement. Tube formats range from 12 x 47 mm to 15 x
75 mm. Use the accompanying adapter for optimal results
when measuring the smaller sized tube formats.
