How to evaluate powder caking with GranuPack

Powder caking is important for industrial applications. Learn how the GranuPack can measure the caking and investigate it thanks to this application note.

Measuring powder air permeability with GranuPack

The GranuPack instrument can be equipped with a measurement cell allowing a permeability measurement. This measurement characterizing the ability of air to pass through a powder is of crucial importance for many applications.

Tapped density characterization: comparison between the GranuPack and standardized methods

Tapped density measurement protocol has been standardized by modern pharmacopeias (USP, Ph. Eur, ISO, …). However, although used for decades, these protocols are based on old techniques inducing a lack of accuracy and repeatability.

Are angle of repose and vertical flow related? (Using the GranuHeap and the GranuFlow)

In general, the lower the repose angle is, the better the powder flowability is. The deviation between the real heap interface and the isosceles triangular heap provides the static cohesive index...

GranuFlow: Improved Laboratory Silo: Comparison vs Hall Flowmeter

The GranuFlow is a straightforward powder flowability measurement device composed of a silo with different apertures associated with a dedicated electronic balance to measure the flowrate...

GranuPack: High resolution tapped density analyzer: Comparison vs Densi-Tap

The GranuPack instrument is an automated and improved tapped density measurement method based on recent fundamental research results. The behaviour of the powder submitted to successive taps is analysed with an automatized device...

GranuDrum : The New Rheometer for Powder

The Granudrum instrument has been developped to measure the dynamic flow properties of a powder for different rotating speed Ω. Therefore, the flowability is measured as a function of the shearing rates and rheological properties like shear thinning or shear thickening could be evaluated...

GranuCharge: The New Powder triboelectric charger

The Granucharge measures the ability of a flowing powder to charge electrostatically by allowing the powder to flow under the influence of gravity and measuring the electrostatic charge of the powder.
