The High-end Dispersion Analyser LUMiSizer® is your complete dispersion lab, all in one instrument. The quick characterization of any demixing phenomena, consolidation and the calculation of the velocity distribution in the centrifugal field as well as of particle size distribution make the LUMiSizer® the instrument of choice for research, development and QA/QC.

Applying the patented STEP®-Technology the instrument determines demixing processes of dilute or concentrated suspensions/emulsions for up to 12 different samples simultaneously. Even different sample cell types and physical references can be measured at the same time.

The stability testing can be accelerated by up to 4500x compared to traditional test tube tests.

Fast stability ranking and shelf-life determinations of undiluted dispersions in original concentration are done in minutes/hours instead of months/years. The multisample analytical centrifuge is ideally suited for characterization and optimization of dispersion properties. It quantifies particle- particle-interactions, the compessibility of particles, flocs, gels and the elastic behaviour of sediments. The concentration, viscosity, complexity and particle size of a wide range of dispersions are easily analyzed. Many applications in research and development as well as in industry benefit from the LUMiSizer®.

The Stability Analyser LUMiFuge® provides you with the objective classification and quantification of demixing phenomena and with the easy and fast determination of stability and shelf-life of dispersions. It is the instrument of choice for process optimization, quality assurance and quality control as well as for process control related research and development.

On the basis of the patented STEP®-Technology, the device determines simultaneously the demixing processes of 8 different dilute or concentrated suspensions/emulsions. Even different sample cell types and physical references can be measured at the same time.The multisample analytical centrifuge LUMiFuge® accelerates the demixing process up to 2300 times compared to traditional test tube tests. Stability tests and shelf-life determinations of original dispersions are up to 2500 times faster than perfomed in a test tube under earth gravity. The analyser, established for many years, features an easy operation, high flexibility (samples, parameters) and large number of applications.

The LUMiReader® instantaneously measures the extinction profile of the transmitted light across the entire length of your sample. Each LUMiReader contains an optical block and temperature control element, each of which can be controlled individually. This ensures maximum flexibility and accuracy.

In addition, the specially designed PSA module also opens new horizons for high resolution particle sizing and allows you to measure the velocity distribution of separating particles. There is no need for you to know any material constants such as viscosity or density.

Our proprietary design ensures that the light strikes the sample across its entire height with minimal intensity variation or light bending, ensuring maximum sensitivity and reproducibility.

Each optical detector has more than 9,000 high-sensitivity micro-scale resolution sensors capable of accurately measuring even the smallest local changes instantaneously across the entire sample height.

This design eliminates the time-consuming and less accurate task of scanning your sample, allowing you to capture any micro-changes occuring in your dispersion.

The LUMiReader also uses a patented tilt technology based on the Boycott effect. The well-known principle allows an increase in the separation rate at 1 g without any additional external forces by tilting the sample from its normal upright position. The magnitude of acceleration (up to 10 times) depends on geometric factors, such as tilt angle, vial dimensions, and sample type.

Analyse under a wide range of viscosities, temperatures, and concentrations. With the advantage of looking at the entire 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.

The LUMiReader® comes certified, factory pre-calibrated and is ready-to-go.

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, suspension, sludges, slurries, foams and powders in real-time. For the first time ever, illuminate your sample instantaneously from top to bottom. Solve your most challenging dispersion problems with complete insight. Go places light cannot.

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 employs monoenergetic and parallel X-rays with the help of a special crystal. More than 1,600 detectors record the transmitted beam, giving an unprecedented resolution over the entire sample cell of 20 mm height. Kinetics of instantaneous recorded transmission profiles across your whole sample are converted into stability and separation rates. Particle concentration, sediment packing density and X-ray attenuation 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. You now can 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 ceramics, cosmetics, pharmaceutics, paint & pigments, construction materials and fillers, as well as mining and petrol industry dealing with complex emulsions, slurries and sludges.

No more dilutions, no more guess work, no more unexpected surprises. Analyse and understand your sample as is, no matter how opaque or concentrated your formulation is.

For all those instances where you need to understand transparent or opaque dispersions, foams, emulsions, or clear microemulsions where dilution is impossible or has unknown side-effects and consequences there is a solution now, and you are looking right at it.

There are many claims out there about the ability to analyze concentrated systems. When pressed however, it turns out that what is concentrated to one person is dilute to another. With that in mind, and wanting to avoid any confusion, all we can state unequivocally is that the LUMiReader X-Ray was designed with one goal in mind: to allow you to analyze and understand concentrated and totally opaque emulsions and suspensions.

How concentrated? As high as you want to go. As opaque as you want it to be. Top to bottom, instantaneously. Yes. Really. No other technology can do this. It is not even close.

The LUMiReader X-Ray is simple to operate. It comes certified, factory pre-calibrated and is ready-to-go.

The Demixing Tester LUMiCheck® is a measuring instrument for the use in research, development and quality control laboratories.

It is used for the fast stability analysis and particle characterization of dispersions, with respect to the comparison of samples of similar type. Up to 8 concentrated or diluted dispersions can, independent of each other, be measured in different sample cells. The instrument is operated using a touch screen.

The easy operation of the instrument using a touch screen, data storage on a SD memory card as well as the optional battery operation permit the use in many field applications and in all kinds of environments and temperatures.

Fast quantitative comparison between samples and qualitative characterization of demixing behaviour, flocculation, sediment formation and stability result in LUMiCheck® applications for beverages and food, construction material, lubricants, fuels as well as for further emulsions and suspensions.

The Adhesion Analyser LUMiFrac® is the new benchmark for determining adhesive and tensile strengths (winner of the Berlin-Brandenburg 2012 Innovation Award, watch video HERE). The LUMiFrac employs centrifugal forces to stress multiple samples at once. It provides adhesive and tensile strength as well as shear strength as an absolute physical quantity in N/mm2.

The analyser accomplishes this by directly applying an incrementally increasing radial centrifugal force to the specimen being tested. It determines with high resolution the RPM at the moment of fracturing. All data is transmitted to the well-known and popular operating software SEPView, which automatically calculates and displays the critical force/strength of failure in real time.

Furthermore, it allows to analyze, compare & calculate statistics and combine results for up to tens of samples. Related data, as figures of fracture pattern, may be taken into account as well. Test sample positioning is as simple as 1-2-3. No clamping or special precautions are needed. Just slide up to 8 samples into marked rotor locations and you are ready to go.

The unique multisample approach of testing 8 samples simultaneously results in an unparalleled accuracy and reduces measuring time by 85%.

Starting as an idea for an easier and time-saving determination of adhesive properties, the multipatented new adhesion testing technology now revolutionizes the analysis of your composite materials and bonded parts. You can even work with multi-layered films; having an immense variety of applications.

The LUMiFrac is a research and QC tool for the adhesive formulation and surface treatment industry; lacquer coatings, joint wood products, composite materials in automotive and aircraft industries, adhesive tapes, multilayer foils for packaging or thin metal films on plastics and optical substrates, e.g., eyeglasses, mirrors, and many more.

Different test stamps are available to cover more than enough material combinations and to enable a wide range of applied loads. In order to facilitate sample preparation specially designed tools are available.

Combine everything you have just read, put it into action, and it makes for not exceptionally accurate and reproducible data, but also for an exceptionally happy user.
