Transilluminator Operation
Set Up

Place the transilluminator on a level work surface. Be sure that an air space exists around
the bottom of the work surface. This space allows for proper air circulation through the unit.

Plug the female end of the power cord into the transilluminator. For 230 volt models, or
those requiring special power cord connectors, ensure that the proper configuration of male
connector or plug is properly connected to the power cord.

Plug the male end of the power cord into a properly grounded electrical outlet. The proper
voltage of the transilluminator is found on the product information label.

The transilluminator may be equipped with a UV Blocking Cover. Remove the brown
protective paper from the cover. Insert the bracket pins on the cover into the holes on the
front of the transilluminator. The cover is adjustable to varying angles for access to the filter
surface.
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 prevent
contact with gel and staining agents.
Press the ON/OFF switch to ON. The UV tubes within the unit will glow beneath the filter.
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
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 which can
damage the filter surface.
To protect the filter glass and minimize moisture and liquids on the glass, it is recommended to
use a UV transmitting Gel-Tray. Refer to the Replacement Parts for ordering information.
Replacing Tubes in the Transilluminator
1. Disconnect the transilluminator from the electrical supply.
2. 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.
NOTE: When powered on, the light tubes within the Visi-Blue transilluminators emit
longwave UV (365nm). UV is a powerful source of UV radiation that will cause damage to
unprotected eyes and skin. As a result, Visi-Blue transilluminators should NOT be operated
when the filter cover is removed!
