What is the Deference between Bulk density & Tap density ?
Answer Posted / spln
Bulk Density (0 taps or Untapped): As is volume in
g/ml.This is called as apparent volume.
Tapped Density: after tapping only we can measure the qty
as g/ml. As per USP two types of methods is there, Method-
I&II.
Based on the powder nature tapping are fixed.500 taps, 750
taps & 1250 taps.(Varience% is NMT 2%)
Naturally all powder grades are fixed in 1250 taps.
After 1250taps also varience is more, then go to USP-II
method or any customer requirement is there then we can use
Method-II.
