Liquid dispersions

Particle size distribution

Particle size distribution analysis is one of the services offered by Alfatestlab for the characterisation of powder, suspension and emulsion products. Accurate particle size distribution over a representative number of particles is a key quality parameter for a variety of products in many industries.

Particle shape

The analysis of particle morphology is one of the services offered by Alfatestlab for the characterization of powders and liquid suspensions. In addition to particle size distribution, particle shape and agglomerates analysis deliver fundamental information for both R&D and troubleshooting of industrial processes.

High pressure homogenizer

In AlfatestLab we are equipped with a Microfluidizer, for the high-pressure homogenization of dispersions. This unique technology that ensures scale-up * allows for the reduction of particle size or emulsion droplets, the disaggregation, the encapsulation of active ingredients, the formation of SUV or liposomes from MLV, and therefore the lab-scale production of nano – stable dispersions. Contact us to process your samples in AlfatestLab, including pre and post process granulometric analysis in the service.
