When it comes to tablets, hardness testing measures the structural integrity and breaking point of a tablet during transportation and manufacturing. For more information about our hardness testing, please contact us.
Tablet Hardness
Tablet hardness can serve as a guide for product development and as a quality-control specification. The tablets should not be too hard or too soft, as a hard tablet could prevent the dissolution of the tablet, which is needed for an accurate dosage. However, if the tablet is too soft it could lead to quick disintegration, and it can easily chip or break during packaging and transport.
Factors that could affect the hardness of tablets are:
- The speed of compression
- The flow and air entrapment
- Formulation variable
- Process parameters
Our Tests
To investigate the hardness of a tablet, we use a Holland C50.
We test the hardness by placing the tablet between two jaws. One of the jaws then moves towards the tablet pushing it against the fixed jaw until the tablet breaks. The load at which the tablet fails across the diameter is then recorded.
