4. Inserting and Defining Filter Slides
4.3 How Do I Install the Custom Filter?
Caution
The filters are precision optical components, which should be handled by
the edges, and not scratched or stored face down in a drawer and so on.
Once the filters are installed in the slide, they are relatively protected, but
care should be exercised when handling or storing them.
In order to install a custom filter do the following:
1. If necessary, remove the securing screw (is used with fluorescence filters
which have an aluminum housing) from the filter slide using a 1.5 mm Allen
key.
2. Remove the inner filter securing ring from the filter slide. The inner filter
securing ring is used with absorbance filters, which do not have an aluminum
housing.
3. Carefully insert the filter into the opening, taking care not to scratch or get
fingerprints on the filter.
Caution
Take care when removing or replacing filters. They are easily scratched.
If necessary, use the eraser part of a pencil to aid in removing the filter from
the holder. Do this with extreme care as the filters are easily damaged.
4. For filters without aluminum housing, place the filter-securing ring into the
filter slide on top of the filter.
5. For filters with aluminum housing, carefully tighten the securing screw to
secure the filter.
6. If there are unused openings remaining after filter insertion, filter dummies
should be mounted in the holes that are still open. With GENios or
GENios
Plus,
the emission
filter slide can have one hole opened, which is
used for luminescence measurements.
7. Affix the bar code that came with the filter to the back of the filter slide. This
is done by first removing the current bar code if one is present, and then affix
the new bar code ensuring that the bar code is in position in the deep
groove. The hole of the label must be placed on the centering pin of the filter
slide.
Do not use the two bar codes currently used for the standard excitation (A)
emission (A), and absorbance (D) filter slides for a combination of
customized filters.
