Powders are very important materials in manufacturing and often as the finished state of what we produce in Ireland

powder is a dry, bulk solid composed of a large number of very fine particles that may flow freely when shaken or tilted. Powders are a special sub-class of granular materials, although the terms powder and granular are sometimes used to distinguish separate classes of material. In particular, powders refer to those granular materials that have the finer grain sizes, and that therefore have a greater tendency to form clumps when flowing. Granulars refers to the coarser granular materials that do not tend to form clumps except when wet.

Powders range is sizes from fine inhalable dusts to coarse granules and they are variously worked or studied by Chemists, Chemical Engineers, Food Scientists, Microbiologists and Minerals companies, to name but a few.

Particular Sciences has always included powder technologies in its products and expertise and believes that we should test powders dry as much as possible.

Instruments like the Dry Powder Feeder for the Mastersizer or the Powder Flow Rheometer from Freeman Technology are market leaders, some are invaluable tools of the trade and others…maybe you should take a look at:



  • Freeman FT4 is the complete test system for powder flow, shear testing and Rheology. It gives you all the information needed to understand your powders behavior.
  • Mastersizer MS3000 was launched recently with a completely new dispersion system for dry powder sizing. The Aero can work with milligrams and upwards, handle free flow robust or fragile or cohesive powders with equal ease and has SOP operation and fine control of feed rates and dispersion pressures.
  • Micromeritics Geopyc was designed to perform Tangentially Applied Pressure (T.A.P.) tests on powders to quantify the manual TAP tests used in so many powder processors.
  • Surface Energy Analyser (SEA) and the Dynamic Vapour Sorption (DVS) analysers from Surface Measurement Systems characterise powder surface re-activity and moisture adsorption behavior.
  • Morphologi G3 is an imaging sytem from Malvern that can uniquely disperse powders over a large slide to count and image each and every particle.
