Consistent fill weight starts with consistent flow.
Capsule filling — dosator or tamping — lives on powder flow and anti-stick behaviour. Poor flow means weight variation and rejected capsules; sticky blends foul the tooling. The right glidant and lubricant keep the line fast and the fills uniform.

What goes wrong, and why
Encapsulation machines meter powder by volume, so uniform flow is everything. Bridging, rat-holing or erratic flow produce weight variation; adhesion fouls dosing pins and tamping heads. Both slow the line and generate rejects.
The Excipients that solve it
Match the grade to the problem
How to specify
What to put in your spec sheet
- Lead with glidant (talc) to fix flow.
- Add minimal Magnesium Stearate for anti-stick — over-lubrication in capsules can slow dissolution just as in tablets.
- Specify consistent PSD so fill weight stays uniform batch to batch.
FAQs
Capsule Filling — common questions
What Excipients improve capsule fill uniformity?
A glidant (talc) for flow and a low level of Magnesium Stearate for anti-stick.
Why is my capsule fill weight varying?
Usually powder flow — improve glidant performance and Excipient PSD consistency.
Does Magnesium Stearate slow capsule dissolution?
It can if over-used; keep the level minimal and well distributed.
