ViewLux uHTS
Microplate Imager
Introduction
A
B
The ViewLux® is the gold standard, ultra highspeed microplate imager, ideal for high throughput
screening of compound libraries requiring the
ultimate in speed, reliability and high quality data.
In fact, over 150 ViewLux systems have been installed in all major pharmaceutical
and many biotech companies worldwide.
The ViewLux system features telecentric lens technology which maximizes light
collection from the sample plate and increases sensitivity while decreasing parallax
error that can result from wells being at different distances from the lens.
Because the ViewLux imager generates
both image and numerical data, it provides
users with additional insight into their biology.
Standard camera lens
Telecentric lens
A telecentric lens has no parallax error
and no loss of photons due to geometry
and wall shading.
The ViewLux imager now features the next
generation of low-maintenance Peltier-cooled,
CCD camera technology that eliminates the
need for a cryogenic cooling system. The
camera is designed for more sensitive
detection, maximum reliability and easy
maintenance.
The ViewLux imager provides similar
performance to a PMT based reader (A), and
its imaging capability delivers additional visual
data (B) for assay development applications.
Choose the best detection for your assay
Latest generation camera system
The system performs luminescence, fluorescence, time-resolved
fluorescence, absorbance and fluorescence polarization which
makes it perfectly suited to a wide variety of today’s fastest
non-radioactive and radioactive assay technologies. The system
shows excellent correlation between results from 384- and
1536-well plates, allowing easy assay miniaturization, and with
the ability to read a 1536-well plate in 30 seconds, the system
can manage throughputs in excess of 200,000 samples per
hour under continuous operation. The ViewLux imager can also
handle plates in a 3456-well format.
• Fast cooling with easy switch off when not in use – ready
to use in 30 minutes after restart
Time-Resolved
Fluorescence
• Compact – no separate camera controller, the cooling
system is integrated into the instrument
• Easy maintenance – no vacuum pumping, no heated
tubes
• Lower background than ever before – more sensitive
detection limit
• Comparable in performance to previous generations of
ViewLux readers for maximum confidence and transferability
Radiometric capability
Luminescence
The ViewLux uHTS Microplate Imager can also read a variety
of homogeneous radiometric assays such as Scintillation
Proximity Assays (with red-shifted SPA beads), Image
FlashPlates™, ADME Tox and environmental FATE analysis
of HPLC fractions in LumaPlates™.
Fluorescence
Intensity
Work the same way with all assay types
The 3 graphs above show the close correlation in performance between
384- and 1536-well for TRF, luminescence and fluorescence technologies
on the ViewLux imager, allowing confident assay miniaturization.
Dual luminescence
The ViewLux uHTS Microplate Imager excels in high
throughput, dual luminescence experiments, particularly
those requiring only a single reagent such as Chroma-Luc™
(Promega Corporation). Its CCD camera design delivers
simultaneous measurement of 1536 wells at each wavelength, so avoiding the signal decay associated with PMT
based readers due to measurement time across the plate.
The ViewLux imager can read all commonly used non-radiometric labels. To change from one technology to another,
simply place the appropriate barcode on the microplate and
the ViewLux system will read it, whether it is on the long
or short edge of the plate. With the one imaging platform
you can work in the same way with all your labels and assay
types, reducing learning curves, saving space and maximizing
the use of robotic automation systems.
A ViewLux system designed for the way you work
A modular design means that the ViewLux imager can keep
up with changes in your application or workflow without
major reinvestment.
Options include:
• Single or double 32-shelf stacker
• External platform for robotic loading
• Combination 32-shelf stacker and external platform for
robotic loading

Reading time with the ViewLux
imager: 4 mins/384-well plate.
Reading time with the TopCount
system: 6 hrs/384-well plate.
CASE STUDY: ViewLux Imager vs TopCount for 14C Radioisotope
Detection in Biological Samples
An example of how a lower throughput application can be improved using the
ViewLux system is shown above. The TopCount™ plate-based scintillation counter
is commonly used to generate a chromatogram from HPLC fractions of separated
metabolites. While highly sensitive in comparison to the usual method of radio-HPLC
detection, the read time in this case is 6 hours. Using the ViewLux imager, the
same result is achieved in 4 minutes with minimal loss of signal to background.
