Tapped Density Testing

Tapped density of powders or granulates is an increased bulk density attained after mechanically tapping a cylinder containing the sample. SOTAX tapped density testers combine Method 1 and Method 2 with different stroke heights (drop) as described in United States Pharmacopeia (USP <616>) and European Pharmacopoeia (Ph. Eur. 2.9.34) in one compact unit. Comparison of the bulk and tapped densities with Compressibility Index and Hausner Ratio indicate the ability of the powder to flow and settle.
