Powder rheology

Alfatestlab provides a complete characterization of powder behaviour thanks to the use of the unique FT4 Powder Rheometer®. The characteristics of a powder are of fundamental importance in the good performances of innumerable industrial processes and in the performance of many products. The behaviour of a powder, for example in terms of flowability, is influenced by intrinsic characteristics of the particles such as: particle size, morphology, surface area, density, porosity, electrostatic charge, hardness etc. Several external or environmental characteristics may also influence the powder characteristics, which can show different and unexpected behaviours. For example, the same powder can flow or not flow according to the degree of consolidation, aeration, humidity, etc. If you are facing such issues, contact us to understand how powder rheology can help you!

Thanks to the FT4 powder rheometer in Alfatestlab, we are able to analyse powder response when simulating different environmental conditions in order to better understand the reason for some behaviours, helping you to improve the quality of your formulations and the efficiency of your production processes.

Zinc Oxide: an additive widely used in different industries

Zinc oxide (ZnO) is an inorganic white powder, insoluble in water and used as an additive in numerous materials and products. Characterization of Zinc oxide powder and particles properties is fundamental to improve final product quality.


Hydroxyapatite (HAp) for a wide range of applications in the biomedical field

The synthetic and natural HA differ in terms of physical microstructure, crystal size, and porosity, but chemical similarities to bone, in both forms, as well as biocompatibility, bioactivity and thermal stability in the body fluid pose Hydroxyapatite (HAp)  as an attractive material for a wide range of applications in the biomedical field.

Pharmaceutical Excipients

Physical properties of excipients influence the stability, bioavailability, and processability of the dosage forms. Alfatestlab is equipped with all the analytical techniques necessary to support you in choosing the right excipient for your formulation: particle size, particle shape, flowability, density, surface area and much more!


An introduction to Silicon dioxide (silica) forms and applications

Silica is one of the most complex and most abundant families of materials: sand, quartz, silica gels, precipitated silica, fumed silica, colloidal silica, mesoporous silica nanoparticles (MSNPs)... Any type of silica material finds specific applications and needs specific physical characterization!


Additive Manufacturing: metal powder check

There is a direct correlation between the physical properties of the powder on the one hand and the performance of the process and the properties of the final components on the other. Therefore, characterisation of the powders allows for process optimisation and improves the finished product.


API: solid state robust characterization in key to cut costs and time!

Characterization of the API solid state is key to reduce possible future manufacturing or formulation issues and cut drug product development costs and time.  Discover more!


Activated carbon: what is it and how to characterize its extraordinary properties?

Due to its high degree of microporosity, one gram of activated carbon can reach a surface area of 3,000 m2 as determined by gas adsorption. Discover more about its extraordinary properties!
