The PTB 311E is a versatile tablet hardness tester designed for pharmaceutical quality control and research laboratories. Engineered in full compliance with USP <1217> and EP <2.9.8> requirements, the instrument provides accurate and reliable measurement of tablet hardness, thickness, width, and diameter to ensure consistent product quality and regulatory compliance.

The PTB 311E features a unique dual-force testing mode, allowing users to perform hardness testing using either linear force increase or linear speed increase. This flexibility enables laboratories to adapt testing methods to specific product requirements and pharmacopeial guidelines. A built-in multiple-point validation procedure for the digital load cell further enhances measurement accuracy and confidence in test results.

Designed for ease of use and precision, the PTB 311E supports multiple measurement units and allows individual parameters to be enabled or disabled as required. The system can also be configured for tensile strength testing of oblong tablets and caplets, making it a highly flexible solution for tablet characterization and quality assurance.
