System Introduction
Gel Imagers and Gel Imagers Plus
The Gel Imagers enables simple documentation of fluorescent and non-fluorescent gels,
membranes, blots, film plates and assays with the ability to save images to a USB storage device for later
quantitative analysis or enhancement for publication.
Images are saved in 8-bit TIFF or JPEG formats allowing the images to be read by most PC or MAC
programs. The Gel Imager system is a cost effective solution for archiving quality images in a compact
standalone package. No computer is required.
The models comes in two configurations:
Gel Imager Plus, a high resolution 1.3 megapixel camera, 8-48mm zoom lens or
Gel Imager - a 0.3 megapixel camera and a 5.7-34.2mm zoom lens.

Camera
System will be configured with one of the two camera
options: 1.3mpx (high resolution) or 0.3mpx .
Both cameras use a USB 2.0 PC connection. All camera
settings are factory pre-set for optimum performance when
viewing gels, films, or membranes under low light level
conditions. UVP Technical Support should be contacted
before making any adjustments to the camera settings.
Lens
The Gel Imager Plus with the 1.3mpx camera is equipped
with an 8-48mm zoom lens fitted with a close-up diopter and
step-up ring. The camera can then be held in a fixed
position. The diopter is for focusing on objects at the focus
length of the Gel Imager.
The Gel Imager with the 0.3mpx camera is equipped with a
5.7-34.2mm zoom lens fitted with a close-up diopter and
step-up ring. The camera can then be held in a fixed
position. The diopter is for focusing on objects at the focus

length of the Gel Imager.
Processor
Internal Storage: 75GB or more
USB 2.0 ports: 1 front, 4 in the back
USB storage device capacity: 1GB (minimum)
Software: Gel Imager software
Ethidium Bromide Filter (EtBr)
The Ethidium Bromide (EtBr) Filter (50mm sq.) UV blocking
band pass interference filter blocks UV and IR radiation
emitted from the transilluminator. The filter is placed in the
filter tray below the camera assembly. The filter allows
visualization of fluorophores from 580-630nm, targeting the
EtBr emission which peaks at 605nm. The EtBr filter can be
substituted for other specific fluorophore filters or removed
when imaging non-fluorescent media (protein gels, colony
plates, etc.) in order to produce brighter images.
Darkroom
The darkroom features:
Gel viewer window
Overhead white light
Wide access doors with UV safety switch
Transilluminator
A transilluminator is included with the Gel Imager. VWR offers a large variety of transilluminators, from
models with 8-watt, single wavelength and single intensity to models with multiple wavelengths and high/low
intensities.
Note: For UV protection, there is a 10-minute timer installed in the Gel Imager. 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. Opening the darkroom door automatically resets the timer.
LCD Touch Screen
The display is an 8-inch VGA color touch screen connected to the darkroom cabinet with tilt adjustment. The
touch screen allows the user to preview, snap, save and print images, as well as select certain preference
options, without the need of an external mouse or keyboard.
A stylus pen is included for increased pointer control for selecting software options on the touch screen.
Focus Target
The focus target fluoresces when placed on a transilluminator or when exposed to overhead UV. The target
provides sharp, fluorescent images to aid in adjusting the focus of the camera.
Removable USB Stick
The removable USB stick has 1 GB memory (minimum) included with the system which connects to the
system allowing transfer of images.

Optional Equipment
Refer to the ordering information section of this manual for optional
equipment part numbers.
Thermal Printer
The thermal printer provides archive quality, 256 grayscale prints, and
five optional cost-effective print sizes.
Converter Plates
The UV/White Converter Plate allows imaging of non-fluorescent
stained media with an ultraviolet transilluminator. The converter plate
is specially coated to convert the 302nm UV output to white light,
rather than using a separate white light box.
The Visi-Blue Converter Plate converts UV to 460-470nm designed
for use with blue excitation samples and SYBR green, SYPRO orange
and GFP stains.

Installing the Filter
Systems include a 50mm sq Ethidium Bromide (EtBr) filter. To install the filter in the Gel Imager darkroom:
Carefully remove the filter from the protective
plastic case, holding the filter at the edges to
prevent fingerprints.
The filter tray is located under the camera
bracket on the right side top of the darkroom.
Slide the tray open.
Place the filter inside the filter tray so that the
text on the edge of the filter is positioned so
the letters are right side up when facing you.
Additional filters are available. Refer to Accessories for ordering information.
Camera Set-up
The camera and zoom lens are assembled at the
factory.
Note: The zoon lens shipped may appear
different than the one pictured at right.
Remove the cap from the lens.
Attach the step up ring and diopter to the
lens. The step up ring and diopter will only
fit one way.
Using the four thumb screws provided,
secure the bracket to the base.
Slide the camera and lens assembly into the
camera bracket. Slide the lens through the
center hole in the gasket. The gasket forms
a seal around the lens.

MAIN POWER button located on the right side
of the unit. All internal components will now
have power.
Turn on the transilluminator and darkroom
power switches.
To power down the system, push the main
power button.
Adjusting the Screen Angle
To adjust the angle of the screen, loosen
the knobs on each side of the monitor.

Operating the Gel Imager Software
The system will go through the boot-up process. When ready, the LCD will display the Gel Imager software
screen similar to the one below:
To shut down the Gel Imager software, touch the X on the bottom left corner of the screen.
To turn the system off, press the MAIN POWER button or power down from the Windows icon on the bottom
right corner of the screen.
Refer to the Gel Imager Software User Manual for further instructions on using the software.
Using the Transilluminator
Once the Gel Imager 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.
Opening the darkroom door will automatically reset 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.

Using the Gel Viewing Window
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 a fluorescent gel on the transilluminator surface. NOTE: The Gel
Imager 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.
