Scott Volumeter / Bulk Density

The bulk density of powders can be extremely difficult to measure since the slightest disturbance may cause a change in the results.

This is the consequence of the relationship between the particles that constitute the powder bulk. This same relationship affects the ability of the powder to flow.

The bulk density of a powder is measured in a Scott Volumeter. It may be described as the density of the powder “as poured” into a measuring vessel.

Tapped density, on the other hand, is the density attained after “tamping down”. This is normally measured using an instrument that lifts and then drops a measuring cylinder containing the powder through a fixed distance.
