TURBISCAN DNS from Formulaction is the first user-friendly platform for stability and dispersibility studies. Dispersibility studies can be executed, while processing the dispersion (at flow) and on the native samples (no added forces, no dilution) through Static Multiple Light Scattering (SMLS), as recommended by the ISO TS 21357.
The flow studies can be performed by either pumping the sample from the process or reactor (circulation function of the Turbiscan DNS: T-LOOP) or by mixing directly in the measurement cell (mixing function: T-MIX).
The stability measurement is performed at rest and the Turbiscan DNS provides a quick (up to 200 times quicker), quantitative and dependable stability measurement of destabilization kinetics in the absence of dilution or mechanical forces.
Highlights of TURBISCAN DNS
Online Particle Sizing
Direct particle size reduction kinetics are done while mixing or during the process through combined functions: T-MIX and T-LOOP. The Turbiscan DNS provides high-frequency measurement (up to 10/second) to accurately track the impact of the mixing parameters.
Fast and Quantified Shelf-Life
The SMLS has extreme sensitivity (ranging up to 200x times quicker compared to the naked eye). Aside from being quick, Turbiscan stability measurement also offers the destabilization mechanism and measures them with the one-click TSI or more in-depth parameters (aggregation speed, migration kinetic).
