without securing the cover. If the cover is missing, a UV Blocking Faceshield must be worn to
avoid UV exposure to the skin. UV Blocking Eyewear should be worn even with the cover in
place to avoid accidental UV exposure.
Using the Transilluminator
Place gel/sample on the filter area. It is recommended to place the gels on a Gel-Tray to protect the
filter surface from cuts and scratches. It is recommended that gloves be worn to avoid contact with
gel and staining agents.
Press the ON/OFF switch to ON. The UV tubes within the unit should be glowing beneath the filter.
If using the transilluminator with an imaging system, the system’s main power is required to be in
the ON position.
When using a transilluminator with multiple UV wavelengths, dial the knob to the appropriate
wavelength setting.
When using the Variable Intensity models, use the variable intensity settings as follows:

High: allows for UV excitation of fluorophores on gels for routine photography and for
excitation of gels with low sample concentration

Medium: Excellent for viewing and quick single-band excision

Low: Allows for positioning and preparation of gels, excising multiple bands and focusing
for photography
The UV Blocking Cover, optionally installed during setup, is adjustable to varying angles to provide
easier access to the filter surface. To adjust the angle, rotate the Phillips head screws (located on
the left sides of the cover’s hinges) clockwise until enough tension has been placed on the hinge to
hold the cover at the desired angle.
After viewing/photographing the sample, turn the transilluminator off.
Cleaning and Care of the Transilluminator
Clean unit surface with a damp soft cloth or sponge. Never use abrasive cleaners (can damage
the UV filter surface).
To protect the filter glass and minimize moisture and liquids on the glass, it is recommended that
you use a UV transmitting Gel-Tray. Refer to the Replacement Parts for ordering information.
Replacing Tubes in the Transilluminator
Disconnect the transilluminator for the electrical supply.
Remove the filter cover: Use a Phillips head screwdriver to remove the four screws on the sides of
the unit. Lift the filter cover off the unit.
Remove the reflectors on the left and right side of the unit: Slide the reflectors up out of the unit.
Remove the tube: Carefully rotate the tube and slide out of the socket. Replace with a new tube by
sliding the tube into the socket and rotating into place.
Insert the reflectors back into place and reattach the filter cover.
