Capsule fill (volume and powder density)
Diluent per capsule and for the batch from the capsule size, the drug amount, and the powders' bulk densities.
Inputs

Tapped, g/mL

Optional; measured average
When to use
- Planning a batch of hand-filled capsules.
Pearls and pitfalls
- Measure tapped bulk density of your powders (mass of powder that fills a graduated cylinder after tapping) or enter a measured blank capsule fill weight.
- Make a few extra capsules' worth of blend for loss.
Why use
Each capsule must be filled completely; the diluent makes up the difference between the drug's volume and the capsule's volume.
Drug volume = drug mass ÷ drug bulk density; diluent mass = (capsule volume − drug volume) × diluent bulk density
