Viscotek 802 DLS |
 The Viscotek 802DLS is a state-of-the-art dynamic light scattering instrument
matched with powerful but user friendly OmniSIZE software to give the most
sensitive and accurate performance available. It makes the rapid characterisation
of proteins, nanoparticles, polymers and biomolecules in solution a routine task.
A small, recoverable volume of your sample is introduced into the sample cell
which is placed into the temperature controlled cell holder. The instrument and
software then make the measurement and the results are displayed in seconds.
A complete analysis from start to finish can be accomplished in minutes.

 Single Mode Fiber - SMF
At the heart of the optics lies the patented SMF technology that gives the 802DLS such
an advantage in accuracy and precision.
The SMF acts as an optical filter, eliminating
extraneous signals and only allowing a single mode of scattered light to reach the
detector. The result is the cleanest signal, enabling high sensitivity and precise size
distributions. The latter being essential for protein crystallography studies.
Dual Attenuation Technology - DAT
The DAT option for the 802DLS boosts the performance of the instrument to a unique
level. Simultaneous digital control of laser power and optical attenuation produce
unprecedented dynamic range from 100% to 0.0001% transmission. This allows the
instrument to automatically operate at the optimum settings for every sample, even
concentrated solutions, without user intervention. No other DLS system has a wider
dynamic range of optical attenuation than the 802DLS.
