Inspect/Clean Excitation and Emission Filters
Applies only to models with fluorescence and/or luminescence capability
BioTek recommends inspecting the filters for dust and other debris every three months. To
clean them, you will need:
l
Isopropyl, ethyl, or methyl alcohol
l
100% pure cotton balls or high-quality lens-cleaning tissue
l
Cloth gloves
l
Magnifying glass
Do not touch the filters with your bare fingers.
1. Turn off and unplug the instrument.
2. Open the access door on the front of the instrument. Slide the filter cube out of its
compartment.
The Filters and Mirrors chapter contains illustrations for identifying the
filters and their unique characteristics. It also contains instructions for
replacing filters, if necessary.
3. Inspect the glass filters for speckled surfaces or a “halo” effect. This may indicate
deterioration due to moisture exposure over a long period of time. If you have any
concerns about the quality of the filters, contact your BioTek representative.
4. Using cotton balls or lens-cleaning tissue moistened with a small amount of high-
quality alcohol, clean each filter by lightly stroking its surface in one direction.
Ensure that the filters remain in their current locations.
5. Use a magnifying glass to inspect the surface; remove any loose threads left by the
cotton ball.
6. Replace the filter cube and close the access door.
