Installing the Filter Kit
Some compounds are photosensitive and may be decomposed during
measurement. This effect can be reduced or eliminated by using a filter to cut
off the highly energetic low-wavelength UV part of the spectrum.
The filter kit (part number G1120-68707) comprises three threaded ring
assemblies which hold different filters. These filters have different cut-off
wavelengths and absorb therefore varying amounts of the UV spectrum. All
threaded rings are labeled with the corresponding cut-off wavelength of the
filters mounted.
Remove the multicell transport from the sample area. Screw the threaded
ring, which holds the filter appropriate for your application, in the circular
opening located at the rear part of the multicell transport. If no threaded ring
is screwed in, the complete light coming from the lamps is let through.
