Description This OptiProbe™ Analyzer is designed for convenient laboratory reaction monitoring and method development scale-up for process applications -- performing measurements directly on the sample, using fiber optic bundles and probe sample interfaces. The OptiProbe™ provides the illumination energy, sensitivity and flexibility to interface to virtually any type of sample matrix. Fiber optic modules are available for use on clear to scattering liquids and slurries, fine and inhomogeneous powders or granules, flakes, pellets and fibers. Fiber optic length and style are determined by the job or the application. The System II OptiProbe Analyzer offers: Ideal for laboratory reaction monitoring for scale-up studies Variety of fiber optic and probe interfaces allows virtually any sample to be analyzed Non-destructive testing No solvents or chemicals Runs with Vision™ Spectral Analysis Software for Windows, a validated data acquisition and chemometrics package. Applications: Designed for use in a liquid inveronment, analyzing chemicals, polymers, and beverrages. The model-5000 (1100nm~2500nm, NIR) and the model-6500 (400nm~2500nm, Vis-NIR) are currently available.
