Dispersibility – Redispersion

A leader in the direct stability measurement for concentrated media and accelerated aging tests, Turbiscan technology now offers the first ready-to-use technology for direct dispersibility and redispersion studies.

Dispersibility corresponds to the ease to disperse a powder into a liquid, to reach spatial uniformity and the desired particle size. Dispersibility is one of the major parameters of dispersed particles and objects, and its optimization can help formulators fine-tune the formulation, search for alternative solvents and additives and adjust process parameters.

  • On-line particle size evolution

  • Non dilution/Native particle size determination

  • Real time measurement


Dispersibility and stability are highly interconnected and a “good” dispersibility is essential to reach the desired shelf-life.

Resuspending properties corresponds to the ease of re-disperse powder after a given settling time. It gives the scientist the information if a suspension can be re-homogenized and what time/energy is needed. Being able to refresh a formulation and retrieve its original configuration after several months of storage is essential for some applications like paints, inks, vaccines, and beverages. The resuspending ability is also fundamental in retrieving the correct color, immune answer, or taste.

Working on native samples without any preparation or product transfer is essential to detect the presence of agglomerate and aggregates, especially for nano particles (ISO TS 21357). SMLS allows for mean particle size determination on a wide range of concentration, from 10-4 up to 95%, and from 10nm to 1mm. SMLS technology is suitable for online studies of the particle size via the mixing and circulating function of Turbiscan.
