TURBISCAN RANGE THE WORLD LEADER IN SHELF-LIFE AND STABILITY ANALYSIS I SAVE TIME Up to 1,000 times faster compared to a conventional visual stability test I DETECT & QUANTIFY Sedimentation, phase separation, aggregation, coalescence, coagulation, creaming… All destabilizations are detected and quantified I OBJECTIVE & RELIABLE Instrumental method, no dilution, no external stress, measure the sample as is – analysis you can trust I WIDE RANGE OF APPLICATIONS Suspensions, emulsions, foams, from low to high concentrations (10-4 - 95% v/v), opaque, clear, coloured samples, from nano to macro (10...

STATIC MULTIPLE LIGHT SCATTERING (SMLS) CUTTING-EDGE STABILITY AND DISPERSIBILITY TECHNOLOGY COUPLED WITH SMART DATA ANALYSIS Turbiscan is based on the Static Multiple Light Scattering (SMLS) technology, the most suitable method to characterize Light source liquid dispersions, directly, in their native state. In most emulsions, suspensions and formulations the concentrations are too high to be analyzed “as is” with light scattering and their characterization requires dilution or mechanical stress, altering their state and structure. SMLS offers the ability to investigate the dispersion state...

STATIC MULTIPLE LIGHT SCATTERING (SMLS) DATA REPRESENTATION DESTABILIZATION DETECTION Scans are overlayed on the same graph and in function of In the case of destabilization, deviations in scans are detected as a function of sample height. Due to the high sensitivity of the SMLS technology, sample height. Each scan has a specific colour from blue - first destabilizations are detected in their very early stage and up to 1,000 times faster than visual observation. scan to red - last scan to easily understand signal variations in function of time. Particle size increase Particle size increase

SHELF-LIFE AND DISPERSIBILITY ANALYZERS | TURBISCAN TURBISCAN SMART ANALYSIS TURBISCAN STABILITY INDEX - TSI PARTICLE SIZE & DISTRIBUTION Turbiscan Stability Index (TSI) sums all the signal variations along the entire sample height and therefore, takes into account all destabilizations occurring. Thanks to the TSI, sample comparison is easy as the higher the TSI, the lower the stability. The key points of the TSI: it is “one-click” and fully automatic, operator-independent, and does not require any data input. The TSI is used in R&D labs for formula stability comparison and optimization, Quality...

SHELF-LIFE & DISPERSIBILITY ANALYZER TURBISCAN THE BEST TECHNOLOGY FOR FAST & NON-INVASIVE STABILITY ANALYSIS

TEMPERATURE RANGE TURBISCAN STABILITY INDEX PARTICLE SIZE DISTRIBUTION THE WORLD REFERENCE STABILITY ANALYZER TURBISCAN LAB allows fast and sensitive identification of destabilization mechanisms (creaming, sedimentation, flocculation, coalescence, …). A temperature-controlled measurement chamber allows stability monitoring at specific storage temperatures or acceleration of the destabilization process with a temperature increase up to 60 °C. TURBISCAN LAB can be used in both R&D and QC labs for the development and routine control of raw materials and final product formulations. The Turbiscan...
