Dimensional checks are quality control procedures in which a sample of items are measured against the manufacturer's specifications. Items that we purchase for production such as vials, plugs and overseals must be carefully measured. And we use a special tool to measure these small distances - a digital caliper. In this video, we demonstrate how to use a digital caliper to measure a 5 mL glass vial to test its height, outer body diameter, outer crown diameter and inner crown diameter.
