Multi-parameter tablet hardness tester for laboratories
Optimize your tablet production line with a versatile tester that ensures precision across multiple parameters, including weight, thickness, and hardness, seamlessly integrating with your laboratory workflow to enhance quality control.

Measures and Aligns Tablets with Precision
The AT50 from SOTAX is a versatile tablet hardness tester designed for precise, multi-parameter testing in pharmaceutical environments. Utilizing Dr. Schleuniger® technology, it handles diverse tablet shapes for weight, thickness, width, length, and hardness assessment. The AT50 is commonly used in the production of tablets like paracetamol and Ibuprofen, aligning with in-process control (IPC) and quality control (QC) requirements.
The AT50 integrates seamlessly into existing laboratory setups or online with tablet presses for continuous, automated testing and calibration. Its compact design features patented AutoAlign™ and SmartAlign™ technologies to ensure accurate tablet positioning, while its universal high-speed feeder expertly manages separation and weighing. The AT50 is CIP-compatible for easy maintenance and features an IP52 protected test area for straightforward cleaning.
With dynamic qualification tools like DQD™ for tablet hardness verification and a built-in Mettler Toledo balance for accuracy checks, the AT50 supports compliance with 21 CFR part 11 and offers full data management through q-doc® software. Available in materials suitable for pharmaceutical standards, this unit is engineered for reliability and adaptability in complex testing scenarios.
