SHqigao HSY-7000 Automated Disintegration Tester (Modular Design with Motorized Rack Inversion)

Overview

The SHqigao HSY-7000 Automated Disintegration Tester is a modular, microprocessor-controlled pharmaceutical testing instrument engineered to perform standardized disintegration testing of solid dosage forms—including suppositories and vaginal tablets—in accordance with the Chinese Pharmacopoeia (ChP) General Chapter 0921 “Disintegration Time Test”. It operates on the principle of mechanical immersion and thermal regulation: samples are placed in perforated metal baskets mounted on a motorized rack, which is submerged in a precisely temperature-regulated water bath. The system monitors time-dependent structural breakdown—defined as complete disintegration into fragments or softening to a non-friable mass—under physiologically relevant conditions (37 °C ± 0.3 °C). Its modular architecture separates the water bath unit from the control and actuation module, enhancing serviceability, thermal stability, and lab-space flexibility. Unlike manual or semi-automated testers, the HSY-7000 integrates programmable rack inversion (180° rotation) at user-defined intervals, replicating mechanical agitation that mimics physiological motility and ensures uniform exposure of all sample surfaces to the medium.

Key Features

• Microcontroller-based temperature regulation with PID feedback loop, maintaining 37 °C within ±0.3 °C across the full 30–40 °C set range
• Three preconfigured test protocols (P1, P2, P3) compliant with ChP requirements for suppository and vaginal tablet evaluation
• Motor-driven rack inversion mechanism delivering precise 180° rotational motion at programmed intervals—no manual intervention required
• Modular design: independent water bath chassis (5 L capacity, triple-beaker configuration) and control/actuation module enable flexible benchtop layout and simplified maintenance
• Stainless steel construction for all wetted parts (cylinders, racks, baskets) ensuring corrosion resistance and compliance with ISO 13485 material requirements
• Over-temperature protection, dry-run detection, and audible/visual end-of-test alerts support operational safety and GLP-aligned workflow integrity

Sample Compatibility & Compliance

The HSY-7000 accommodates standard ChP-compliant cylindrical test units (Ø52 mm × 60 mm) and supports suppositories (fatty or water-soluble bases), vaginal tablets, and other thermosensitive solid dosage forms requiring disintegration assessment under simulated body conditions. The metal rack geometry—Ø50 mm outer diameter, 4 mm aperture, and 30 mm plate spacing—is dimensionally aligned with ChP specifications to ensure unrestricted medium flow and reproducible sample positioning. While designed primarily for ChP compliance, its operational parameters (temperature accuracy, timing resolution, mechanical repeatability) meet foundational requirements referenced in USP <701>, Ph. Eur. 2.9.1, and JP 17 General Test 2.07. The instrument’s deterministic timing logic and hardware-level inversion control facilitate audit-ready execution suitable for GMP environments where protocol adherence and traceability are mandated.

Software & Data Management

The HSY-7000 operates via embedded firmware with no external PC dependency. All test configurations (protocol selection, start time, duration, inversion schedule) are stored in non-volatile memory and recalled via intuitive membrane keypad navigation. Real-time status indicators (elapsed time, current temperature, rack position) are displayed on a high-contrast LCD. Though not equipped with network connectivity or electronic data capture (EDC), the system supports GLP-compliant documentation through printed or manually recorded test logs—including batch number, operator ID, ambient conditions, and observed disintegration endpoints. For laboratories implementing 21 CFR Part 11 compliance, integration with validated LIMS or ELN systems can be achieved via external time-stamped log export using optional RS-232 interface (available upon request).

Applications

• Quality control release testing of suppositories (e.g., acetaminophen, indomethacin, progesterone) per ChP and international pharmacopoeial monographs
• Stability-indicating method development for vaginal tablets undergoing formulation optimization (e.g., polymer matrix erosion kinetics)
• Comparative disintegration profiling during generic product development and bioequivalence support studies
• In-process testing during manufacturing scale-up to verify consistency of melt behavior across batches
• Educational use in pharmaceutical sciences curricula for teaching disintegration mechanics and regulatory test methodology

FAQ

Does the HSY-7000 comply with USP <701> or Ph. Eur. 2.9.1?
It meets the core physical and operational criteria (temperature control, timing accuracy, basket dimensions) referenced in these standards; however, formal USP/Ph. Eur. certification requires third-party verification per each laboratory’s validation protocol.
Can the inversion interval be customized beyond the three preset modes?
No—the firmware supports only P1, P2, and P3 as defined by ChP. Custom timing requires firmware revision, available under OEM support agreement.
Is calibration traceable to national standards?
Yes—temperature sensors are factory-calibrated against NIM-traceable references; users receive a calibration certificate with uncertainty budget per ISO/IEC 17025 guidelines.
What maintenance is required for long-term reliability?
Quarterly descaling of heating elements, biannual verification of rack alignment and inversion torque, and annual recalibration of temperature sensors are recommended per the manufacturer’s maintenance schedule.
Are replacement cylinders and racks available as spare parts?
Yes—standard Ø52 mm cylinders and Ø50 mm racks with 4 mm apertures are stocked globally; custom geometries require minimum order quantities.
