Dosing Disc Calculation

This document provides information on dosing disc thickness for different capsule sizes. It includes tables with the thickness in mm for various capsule sizes from 00 to 5. It also provides details on calculating the dosing disc thickness based on fill weight, capsule volume, compressibility ratio, and dosing disc hole size. The recommended approach is to select a thickness 0.5 mm larger than the actual calculated size to ensure proper filling.
