Essentially, the difference between bulk and tapped density is a measure of the interparticle interactions that affect powder flow. This is especially important when combining ingredients to be used in a pharmaceutical capsule or tablet. Using a dual tap density tester, Micromeritics Analytical Services reports bulk density, tapped density, a compressibility index, and the Hausner Ratio. Further discussion of these terms and equations are found in USP<616>.
