Overview
The intelligent four-function tablet tester is used to test the hardness, friability, disintegration time limit, and dissolution rate of pharmaceutical tablets. It is a multi-purpose drug test instrument designed for comprehensive physical testing. The AELAB ZPJ-4 and ZPJ-6 integrate smart control, automatic detection, and stable operational precision for quality assurance in laboratory environments.
The system adopts a magnetic water pump circulating water flow to ensure uniform bath temperature. Automatic temperature control, timing, detection, latching, and cyclic testing support continuous operation with enhanced measurement reproducibility.
⚙️ Design & Construction
The AELAB ZPJ-4 & ZPJ-6 feature a Stainless Steel SUS316L dissolution framework, rotation baskets, and paddle rods designed for long-term chemical resistance. The heating assembly ensures uniform thermal distribution, while the three dissolution cups and drive rods are arranged in a stable, single-row configuration. Manual head-lifting provides flexible access for cleaning and maintenance. High-precision pressure sensors enable accurate tablet hardness measurement with digital display feedback.
🔬 Working Principle / Testing Method
The ZPJ Series conducts dissolution, disintegration, friability, and hardness testing under controlled temperature, rotation speed, and timing parameters. Dissolution testing uses programmable paddle or basket rotation with ±0.5 mm/±1.0 mm swing accuracy. Disintegration testing operates dual-path baskets with synchronized reciprocation. Friability testing controls rotational cycles precisely, and hardness testing quantifies compressive force using a calibrated load cell. All real-time values and preset parameters are displayed digitally to ensure correct test execution.
