Vilber Lourmat gel documentation systems are supplied
with a complimentary software. These user-friendly
software enable image enhancement (inversion,
contrast, brightness, rotation, mirroring, etc.,)
and analysis (molecular weight, quantification
of volumes, colony counting, etc.,).

the Bio-Vision system. - Bio-Capt is supplied with the
Bio-Print system. - Photo-Capt is supplied with the
Doc-Print system. > More info
Real time for gel positioning without damaging
Real time is a key feature regarding the ease-of-use
of a gel documentation system. The first step
of image acquisition is gel positioning and zoom
lens adjustment. Real time image preview facilitates
time for natural signal amplification
The emitted light signal coming from the gel
is relatively faint. A feature called integration
can compensate for this low light situation.
Integration allows the CCD camera to perform
a timed exposure with the sensor collecting
the incoming light over an extended period of
time. This means that the sensor will accumulate
more photons from the gel. In most cases, a
few seconds integration time is sufficient.
Gray-scale monitoring for an optimum image
The image gray scale is crucial for quantitative
accuracy. In electronic imaging systems, the
intensity range between white and black is divided
into a number of graduations known as the gray-scale.
The number of graduations in the scale is determined
by the specifications of the camera. With most
gels, a real time image will have few gray-levels.
Increased integration times will enhance the
number of gray-levels. In order to obtain an
optimum image, the user has to monitor the current
gray-scale in order to modify the integration
Saturation warning for accurate analysis
Saturation occurs if the amount of light collected
by the camera exceeds its capacity. In such
case, the image is over-exposed and the integration
time should be reduced. A saturated image is
inappropriate for quantification. It is therefore
crucial to monitor the saturation while acquiring
the image. This is done with the pixel saturation-warning
is dedicated to both Syber-Green and standard
Ethidium bromide gels.
The transilluminator is equipped with an innovative
UV filter that highly improves the quality of
gel documentation. Thanks to the Super-Bright
filter, the excitation light is isolated from
the gel emission light.
allows the use of our exclusive F410 camera
filter which totally transmits the signal of
Syber-Green or Ethidium bromide gels.
The signal is therefore 25% enhanced compared
to that obtained with a standard transilluminator.
stand-alone or computer based systems comply with
very strict GLP standards. As soon as the image
is saved, a shadowed GLP file is automatically
It includes all the acquisition parameters such
as the integration time, the date and hour of
image capture, the original name of the image,
All subsequent image treatments are also tracked
and recorded (image rotation, contrast modification,
etc.). Additional comments can be added from
any Vilber Lourmat software.
