TURBISCAN Classic  / MA 2000
The TurbiScan MA measures the destabilization of concentrated dispersions and determines the mechanisms driving it.  The TurbiScan is used to improve formulations, document stability tests, and shorten stability test time.
The TurbiScan MA tests emulsions, suspensions and foams without dilution:
Up to 60 % v/v concentrated
With 0.05 to 5,000 micron mean particle size
HOW IT WORKS 
Multiple light scattering measurement for concentrated dispersions analysis
This vertical scan macroscopic analyser consists of a reading head that moves along a flat-bottomed cylindrical cell to scan the entire sample length. The reading head consists of a pulsed near infrared light source and two synchronous detectors:

- The transmission detector monitors light transmitted through the product;

- The backscattering detector receives light backscattered by the product (135°).

The reading head acquires transmission and backscattering data every 40 microns along the sample tube for a maximum length of 80 millimeters. This fingerprint of the product characterizes its homogeneity,  particle concentration, and mean particle diameter. Results are represented on the software screen by a curve showing the percentage of backscattered or transmitted light as a function of the sample tube length (in mm).
The acquisition scan is then repeated over and over with a programmable frequency and results are superimposed on a time scan graph. The stability or instability of the product can then be determined by analysing the time graph.  If the scans at different times overlap, the product is stable.
