Separation Analyser LUMiReader^® 

The separation Analyser LUMiReader^® determines the demixing of suspensions and emulsions for a large range of particle sizes under original storage conditions, e.g. sedimentation, flocculation and clarification. The demixing process is accelerated using a patented measuring principle, without stressing the sample by additional mechanical forces.

By means of the patented STEP-Technology^®, the change of transmission over the time, due to particle migration or alteration, is recorded simultaneously over the whole sample height with a local resolution of < 40 µm. Up to three different samples are measured simultaneously, a high efficiency is achieved. Temperature control up to 60 °C meets the requirements of many applications in research and development and industry, e.g. in petrol and pharmaceutical industries.

Multi-Wavelength Analyser LUMiReader^® PSA

with Particle sizing according to ISO 13317

The multi-wavelength LUMiReader^® PSA measures space and time resolved extinction profiles (STEP technology) at different wavelengths. This allows for the determination of changes in concentration and/or particle size of the samples. The differences due to the variation of the wavelength can be used for the comparison in product quality influenced by changes in particle size induced by flocculation, coalescence, etc. 

The multi-wavelength LUMiReader^® PSA is an instrument for the comprehensive understanding of complex industrial products in an easy way, giving hydrodynamic particle density, separation velocity distribution and particle size distribution in addition to the direct stability result. The particle size distribution is determined within the range from 500 nm to hundreds of µm.
