LUM GmbH – LUMiSizer
The LUMiSizer is an evolutionary development based on the LUMiFuge platform with some significant additional capabilities that instantaneously measures the extinction (space- and time-resolved) of the transmitted light across the entire length of your sample using the STEP-Technology.
Because of an enhanced optical system, the LUMiSizer lets you analyse particle and droplet velocity distributions for creaming and sedimentation phenomena without the need of any material data and performs particle sizing (ISO 13318- 2).

Brand
The LUM GmbH is one of the leading producers for analytical devices for dispersion analysis and particle characterization. On the basis of longtime experiences in the field of fluid mechanics, rheology and colloid chemistry the company, founded by Prof. Dr. D. Lerche in 1994, has developed the innovative STEP-Technology®, which is the technical platform for different product lines. Or measuring equipment is used for the fast, reliable and comprehensive characterization of any demixing phenomena in dispersions and the testing of bonding and adhesive strength of composite materials.
