The Capsule Filling Capacity table is shown as below.  Size #000 is our largest capsule and its filling capacity is 1.35ml.  Size #4 is our smallest capsule and its filling capacity is 0.21ml.  The filling capacity for different size of capsules is depends on the density of capsule contents.  When the density is bigger and the powder is finer, the filling capacity is larger.  When the density is smaller and the powder is bigger, filling capacity is smaller. The most popular size in global is #0, for example, if the specific gravity is 1g/cc, the filling capacity is 680mg.  If the specific gravity is 0.8g/cc, the filling capacity is 544mg.  Best filling capacity requires suitable capsule size in order to perform smoothly during filling process. If filling too much powder, it will let capsule become un-locked situation and content leakage.  Normally, many health foods contain compound powders, so their particles have different sizes.  Therefore, choosing specific gravity at 0.8g/cc as a filling capacity standard is much safer. Our pearl gelatin empty capsule is disintegrated and absorbed mostly by the stomach.
