The multi-wavelength Separation Analyser LUMiReader. PSA, enables you to accurately measure the instability and real-time separation kinetics of your emulsion/suspension directly for a wide range of viscosities and concentrations. An external thermostat allows for high precision thermoregulation from 4 – 80 ÅãC. The analyser uses the patented cutting-edge STEP-Technology., which permits to obtain Space- and Time-resolved Extinction Profiles over the entire range of your sample in situ (every second) with high accuracy. Parallel light (near infrared, red and blue) illuminates the sample cell and the transmitted light is detected by thousands of detectors. Transmission is converted into extinction and particle concentration may be calculated. With the advantage of looking at the sample from top to bottom instantaneously, you can observe and understand different stability/ instability phenomena concurrently; for example, creaming, sedimentation, coalescence, aggregation and flocculation at original product concentration under normal storage conditions.
