Tapped density is used to know the flow ability of the
sample.The flow ability of the sample is importent factor
to determine in pharmaceuticalindustry by determining the
compressibility factor or houser ratio.Samples with better
flow will have ratio nearer to houser ratio 1.

flow ability is importent to determine because the tablet
formation will depend on it.Compresibility factor can also
be known with tapped density.

Bulk density or un tapped density or pour density is the
density of the sample which is un tapped.Where as tapped
density is density the sample occupies after tapping it
mechanically.

There are two methods to determine tapped density.
USP methdod I
USP method II

Tapping is done mechanically by raising the measuring
cylinder and allow it to fall freely under gravity.

density= sample taken/volume it occupies.
