Using the Transilluminator
In the BioDoc-It
Once the BioDoc-It darkroom power is turned on, power is supplied to all components including the jumper
power cable that supplies power to the transilluminator. To use the transilluminator, turn the transilluminator
power on.
For UV protection, there is a 10-minute timer installed in the system. The timer shuts off the transilluminator
after 10 minutes of operation. A switch on the front of the darkroom allows the user to reset the timer. When
darkroom door is opened, this automatically resets the timer. When the timer runs out, press the timer again.
This prevents the transilluminator from being on for too long and prevents damage to gels.
Refer to the Transilluminator Manual for additional instructions on using the transilluminator.
In the VisiDoc-It
To use the transilluminator, turn on the transilluminator power on the front of the unit.
NOTE:
When the transilluminator is illuminated, ensure that the UV blocking cover is in position to prevent
any exposure to UV.
Using the Gel Viewing Window in the BioDoc-It
The Gel Viewer has a pressure-sensitive clasp. Press firmly to open the viewer. The glass is UV blocking
while providing a clear view to the transilluminator surface for visibility of samples without opening the door.
Image Focusing
Prior to capturing any images, prepare the image focus capabilities of the system:
Turn on the transilluminator and place the
Fluorescent Focus Target
on the transilluminator surface.
NOTE: The BioDoc-It darkroom has a UV safety switch that turns the transilluminator off when the door
is open. After closing the door, be sure the overhead white light switch is turned off.
While watching the LCD screen, rotate the lens f-stop adjustment so that the image is bright enough to
see on the screen.
Rotate the lens focus adjustment on the lens. Adjust this so that the image appears in clear focus on the
LCD monitor.
Note:
Once the proper zoom range is set, the lens will have to be refocused when
zoomed in completely.
Rotate the zoom lens adjustment on the lens, so that the image is as big as possible. Readjust the
focus ring on the lens, making the image clear. Adjust the zoom so that the object of interest is within
the picture on the LCD monitor.
