Principle of operation

The LUMiReader® X-Ray is the first dispersion analyser designed for one purpose only: to study dispersability, stability, separation, and consolidation phenomena for completely transparent to completely opaque emulsions or suspensions. For the first time ever, illuminate your sample instantaneously from top to bottom. Solve your most challenging dispersion problems with complete insight.

Our patented solution combines x-ray vision with the proven STEP-Technology, permitting highest spatial resolution, short sampling intervals and powerful detection technique. The LUMiReader® X-Ray creates monochrome and parallel x-rays with the help of a special crystal, which transmits the entire sample cell of 20 mm height.


More than 1,600 detectors record the transmitted beam, giving an unprecedented resolution . Instantaneous transmission profiles across your whole sample are converted into stability and separation rates. Particle concentration, sediment packing density can also be calculated based on the extinction profiles.

The obtained Space- and Time-resolved Extinction Profiles allow you to measure and understand particle stability, phase separation, and sediment consolidation in systems that where up to now, unknown frontiers of science and technology.


The LUMiReader X-Ray allows you to optimize your formulation, measure its stability, and perform accurate shelf life tests, regardless of the shape or concentration of your dispersed particles and droplets. In-situ, real-time, non-invasive and non-destructive.

Typical applications are cosmetics, pharmaceutics, paint & pigments, construction materials and fillers, as well as mining, ceramics and petrol industry dealing with complex emulsions, slurries and sludges.

Comes with state-of-the-art software SEPView.

The LUMiReader X-Ray comes certified, factory precalibrated and is ready-to-go.
