| Principle of Operation |
Operates by applying a controlled force to the tablet until it fractures, providing a quantitative measure of its hardness. |
| Components |
- Load Cell or Force Sensor: Measures the force applied to the tablet.
- Tablet Holder: Securely holds the tablet during testing.
- Actuator: Applies force to the tablet, driven manually or through automation.
- Control System: Sets testing parameters such as force range and speed.
- Display Unit: Shows measured hardness values and relevant information.
- Software Interface: Advanced models may include software for data management and analysis.
|
| Operation |
- Tablet is securely placed in the holder.
- Testing parameters are set on the control system.
- Actuator applies force until tablet fractures, measured by the load cell.
- Hardness value is displayed or recorded.
|
| Types |
- Manual Hardness Testers: Requires manual operation by an operator.
- Semi-Automated Hardness Testers: Combines manual loading with automated force application.
- Fully-Automated Hardness Testers: Automates the entire testing process.
|
| Applications |
- Quality Control: Ensures consistency and integrity of tablet formulations.
- Research and Development: Optimizes formulations by assessing the impact of different parameters.
- Regulatory Compliance: Meets pharmacopeial standards for tablet hardness limits.
