The ST-1 is a compact measuring instrument for stability and ageing analysis. Quick stability evaluation of high viscosity solvents. Non-contact measurement of particle and droplet migration and suitable to evaluate creaming, sedimentation, agglomeration and coalesence. The ST-1 can evaluate the stability at real storing conditions as in the warehouse or refrigerator. Up to 6 scan towers can be added for efficient control of solvents at independent temperature in the range from 4 to 80 °C.
