LUMiReader® Overview

Each LUMiReader contains an optical block and temperature control element. In addition, the specially designed PSA module also opens new horizons for high resolution particle sizing and allows you to measure the velocity distribution of separating particles. There is no need for you to know any material constants such as viscosity or density.

Our proprietary design ensures that the light strikes the sample across its entire height, ensuring maximum optical sensitivity and reproducibility.

The optical detector assembly features micro-scale spatial resolution capable of accurately measuring even the smallest local changes instantaneously across the entire sample height.

This design eliminates the time-consuming and less accurate task of scanning your sample, allowing you to capture even very fast micro-changes occuring in your dispersion without mechanical vibration.

The LUMiReader also uses a patented tilt technology based on the Boycott effect. The well-known principle allows accelerated, real-time stability testing at gravity by tilting the sample from its normal upright position. The magnitude of acceleration (up to 10 times) depends on geometric factors, such as tilt angle, vial dimensions, and sample type.

Analyse in a wide range of viscosities, temperatures, and concentrations. With the advantage of looking at the entire sample from top to bottom instantaneously, you can observe and understand different stability/instability phenomena concurrently; for example, creaming, sedimentation coalescence, aggregation and flocculation at original product concentration.

Benefits
