Tablet hardness testing, also called breaking force, is used to measure the mechanical integrity of tablets to predict how they will perform during handling, transportation, and storage.
How Does a Tablet Hardness Tester Work?
The process of tablet hardness testing involves placing the tablet between a fixed jaw and a motorized jaw that presses forward until the tablet fractures. Measurement principles include constant speed (the rate of jaw movement) or constant force. Results can be displayed in newtons, Strong-Cobb, or kiloponds. Tablet hardness testers can also measure thickness, diameter, and weight for a variety of tablet shapes and sizes. They are used in the pharmaceutical industry for quality control, R & D, and in-process testing.
What Are Different Types of Tablet Hardness Testers?
Systems range from manual or semiautomated to fully automated units with automatic feeders and alignment systems to ensure reproducibility. Interchangeable jaw plates make for easy accommodation of different tablet shapes.
