Formulaction

The Turbiscan ags is the new generation of instruments in the Turbiscan range. It consists of the Turbiscan LAb and a robot with three thermoregulated blocks for the storage of the samples. This instrument is dedicated to formulation screening regarding their long-term stability behaviour (shelf life) for control or R & D purposes. It is also a well suited instrument for a systematic quality control of concentrated dispersions at the end of the manufacturing process.

The Turbiscan LAb offers the possibility to accelerate and document ageing tests. In this regard, variations in particle size due to coalescence or flocculation can be monitored via the kinetics giving changes of the particle mean diameter over time. Migrations of the particles leading to sedimentation or creaming are analysed by direct and easy calculation of the migration velocity and the thickness of the sediment or cream phases.

The Turbiscan OnLine offers the possibility to monitor in real time the physical properties of dispersions (mean diameter, volume fraction), during processing, by online measurement. This dynamic method of working instantaneously monitors the effects of the process parameters, (stirring system, grinding, pressure, temperature, method of addition, surfactant effects, pH), on the state of the dispersions by measuring in real time the mean diameter or the volume fraction of the dispersed phase.

The Turbiscan Classic MA 2000 is the tool dedicated to optimise the pre-formulation work by giving an insight into instability trends. It can monitor the effect of the various components in the product (nature of both phases, concentration and nature of surfactant) by detecting destabilisation phenomena such as particle migrations (sedimentation, creaming) and/or particle size variations (coalescence, flocculation) 20 to 50 times faster than visual detection. Moreover, this objective and discriminating method analyses the intensity and the nature of the destabilisation phenomena.
