Available from Viscotek (www.viscotek.com) the Model 270 Dual Detector is an entry-level system for laboratories looking to make detailed characterisation of proteins, and other biomolecules.

The Model 270 may be configured as a stand-alone Low Angle Light Scattering (LALS) detector or as a LALS and Viscometry dual detector. The unique dual detector Model 270 can be added to any commercial GPC/SEC system equipped with a concentration detector, instantly converting it into a powerful triple detector system.

Previously only available on Viscotek's market leading TDA system, LALS detection is now available on an entry-level system. This means that for a wide range of proteins, peptides and biomolecules researchers can make routine direct determination of absolute molecular weight on the highly affordable Model 270. Unlike multi-angle light scattering techniques that can only determine molecular weight by extrapolation, the model 270 LALS measures molecular weight directly and thus is inherently more accurate. Incorporating patented optical technology that will effectively operate at an angle of only 7 degrees the LALS detector represents a major breakthrough in light scattering technology. Configured with an additional differential viscometer the Model 270 provides valuable further information including hydrodynamic radius, density and conformation as well as providing structural data such as branching and aggregation.

Founded in 1985, Viscotek is the global leader in Gel Permeation Chromatography ( GPC ) / Size Exclusion Chromatography ( SEC ) detectors, software and systems for the characterisation of natural and synthetic polymers, copolymers, proteins, protein conjugates, aggregates and excipients. Viscotek's innovative products and technologies are backed in Europe, North America and Asia by superior technical service and analytical support.
