Microstructure thermal analyzer

Rheolaser CRYSTAL analyzes phase transition of complex materials containing oils, fat, waxes, polymers… It directly measures smallest change (nanometer scale) in microstructure during phase transition. Thanks to the non-invasive optical method, a precise and sensitive study is possible. Measuring the structure on a macroscopic sample (from 0.05g to 5g) overcomes general issues with sample heterogeneities. It also reduces the risk of damaging the structure during the sampling. Temperature cycles and accelerated aging tests can be performed thanks to fast temperature control. This is particularly interesting when characterizing finished products like oil formulations, lipsticks... to detect at early stage fat exudation, polymorphism, or even chocolate blooming.

Highlights of Rheolaser Crystal

Temperature cycles stress

Unique temperature specifications offer the possibility to characterize structure properties under constant temperature stress or in accelerated ageing conditions: temperature ramps and cycles
at 0.1 - 25°C/min

Microstructure thermal characterization

> Crystallization temperature & time
> Melting point temperature & time
> Polymorphic transitions
> Phase inversion

Direct sample analysis

Specially designed sample holders allow the measurement without the risk of damaging the structure. Any sample form from liquids, gels and solids can be analyzed (sample size from 0.05 to 5g).

Sensitive thermal analysis

DWS technology detects particle mobility on the nanometer scale, providing unmatched sensitivity to thermal analysis.
