3.2 Darkroom Enclosure, Emission Filters, and Illumination Sources
The Universal Hood II is designed to capture fluorescent and chemiluminescent images without using a
photographic darkroom. The enclosure has built-in white light epi-illumination and UV
transillumination. An optional white light transilluminator (catalog #170-7950) or a white light
conversion screen (catalog #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 be 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 fluorescent applications as well as the ability to image chemiluminescent samples
(no filter).
Bio-Rad Laboratories, Inc. offers a selection of filters and illumination sources.
