The Dispersion Analyzer LUMiSizer (photo) is said to be a complete dispersion laboratory in a single instrument. The LUMiSizer simultaneously determines the demixing of 12 different dispersions at original concentration, based on a patented STEP Technology. Due to acceleration of demixing in the LUMiSizer up to a factor of 2,300, information about colloidal stability, surfactant influence, particle size, agglomeration and flocculation of dispersions is obtained in a short time. The variation of the centrifugal force — comparable to a falling sphere viscometer — also provides first information about the rheological behavior of the dispersion. — L.U.M. GmbH, Berlin, Germany
