The Turbiscan TOWER is a multi-sample stability analyzer that allows to perform full characterization of the colloidal stability of concentrated dispersions, such as emulsions, suspensions and foams at real storage conditions.
With 6 measurement positions, the Turbiscan TOWER allows for a simultaneous comparison of formulations to be achieved more efficiently and in a quantified manner. Thus, providing a deeper understanding of destabilization mechanisms such as creaming, sedimentation, flocculation and coalescence.
Stability analysis measurements can be performed within the temperature range of 4 to 80 °C, thereby accelerating destabilization processes and/or reproducing storage conditions, depending upon the specific user requirements. Overall, this stability analyzer exhibits a vertical set-up that provide users with high performance and smaller bench footprint.
Product Features
Multi-sample Stability Analysis
- Up to 6 samples can be characterized without requiring any prior dilution or mechanical stress procedures to be performed.
- Formulations with concentrations of up to 95% can be tested in their native state, thereby providing users with a unique insight into particle migration and size variation.
Stability and Size Measurement
- Quantitative monitoring of dispersion stability
- Shelf life and long-term stability analysis
- Migration velocity
- Aggregation and agglomeration kinetics
- Mean diameter
- Dispersibility ratio
- Volume fraction
Real Storage Conditions
The operating temperature range from 4 °C to 80 °C allows users to accelerate measurement time and/or observe destabilization processes that may occur under real storage conditions.
Turbiscan Stability Index (TSI) Scale
This provides a single value to rapidly assess and rank formulation stability, independently of occurring phenomena. It is now possible to evaluate sample stability with just one number.
