Micromeritics Analytical Services (MAS) – Now Offers Bulk and Tap Density Services According to USP <616>
Bulk density and tap density are common tests used throughout the pharmaceutical industry. A comparison of the bulk density and tapped density can provide important information to predict the flow properties and compressibility of both active ingredients and excipient compounds.
Nocross, GA - 9/18/2006 -- 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>.
