3.2 Darkroom Enclosure, Emission Filters, and Illumination Sources
The Universal Hood II is designed to capture fluorescence and chemiluminescence images
without using a photographic darkroom. The enclosure has built-in white light epi-illumination
and a UV transillumination. An optional White Light Transilluminator (170-7950) or a White
Light Conversion Screen (170-8001) may also be used with the system.
For easy sample loading, the UV transilluminator is located in the drawer of the Universal
Hood II and can accessed from the front of the enclosure. For your convenience, the lights in
the darkroom enclosure turn off automatically after about 15 minutes. This time period can be
extended indefinitely by pressing the HOLD button.
The Universal Hood II has a three position Filter Slider that offers the flexibility of using two
different emission filters for fluorescence applications as well as the ability to image
chemiluminescence samples (no filter).
Bio-Rad Laboratories offers a selection of filters and illumination sources.
