Haosoo DT08 Automated Dissolution Tester

Overview

The Haosoo DT08 Automated Dissolution Tester is an offline, fully integrated pharmaceutical dissolution testing system engineered for compliance with USP , , and EP 2.9.3 standards. It operates on the principle of paddle or basket apparatus (Apparatus 1 and 2), enabling precise simulation of in vivo drug release kinetics under controlled hydrodynamic and thermal conditions. Designed for QC laboratories in pharmaceutical manufacturing, contract research organizations (CROs), and regulatory-focused academic facilities, the DT08 delivers reproducible dissolution profiles through its closed-loop temperature regulation architecture, synchronized dosing mechanics, and cup-specific thermal validation. Unlike semi-automated or manual systems, the DT08 incorporates intrinsic process safeguards—including real-time liquid-level verification and microbiological suppression in recirculating fluid paths—to minimize experimental variability and ensure data integrity across extended test durations (up to 24 hours).

Key Features

• Independent cup-wise temperature sensing and PID-controlled heating—each of the eight dissolution vessels maintains ±0.2 °C stability at setpoints from 30 °C to 45 °C, with NIST-traceable calibration support.
• Automated dosage delivery with programmable timing: single-bolus, staggered, or sequential tablet/capsule introduction synchronized to start time or predefined intervals.
• Integrated UV-resistant germicidal module within the recirculation manifold—utilizing low-pressure mercury vapor lamps emitting at 254 nm—to suppress microbial proliferation in deionized water reservoirs during overnight or multi-day assays.
• Android-based embedded OS with 7-inch capacitive touchscreen interface—supporting intuitive method creation, parameter locking, and real-time profile visualization without external PC dependency.
• Comprehensive system diagnostics: power-on self-test (POST), heater continuity verification, motor encoder feedback validation, and thermal fuse redundancy monitoring.
• Regulatory-grade data governance: time-stamped audit trail with immutable event logging (user login/logout, method modification, calibration entry, print command), role-based access control (administrator, analyst, reviewer), and biometric fingerprint authentication.

Sample Compatibility & Compliance

The DT08 accommodates standard USP-compliant dissolution vessels (1000 mL, cylindrical geometry) and supports all conventional dosage forms—including immediate-release tablets, delayed-release capsules, extended-release matrix tablets, and orally disintegrating films. Its mechanical design conforms to USP Apparatus 1 (basket) and Apparatus 2 (paddle) dimensional tolerances, with rotational speed accuracy of ±1 rpm across the 25–200 rpm range. The system meets ISO/IEC 17025 requirements for test equipment qualification and supports IQ/OQ/PQ documentation templates. When configured with validated firmware and electronic signature modules, it satisfies FDA 21 CFR Part 11 criteria for electronic records and signatures in GMP environments.

Software & Data Management

Data acquisition and reporting are managed through Haosoo’s proprietary DissolutionSuite™ v3.x software—accessible locally via touchscreen or remotely via secure Wi-Fi link. The platform enables method import/export in XML format, automated CSV/TXT export with timestamped headers, and direct thermal printing of final reports including dissolution curves, mean dissolution time (MDT), and similarity factor (f2) calculations. All raw sensor logs (temperature, rotation, time) are stored in encrypted SQLite databases with SHA-256 hashing. Remote firmware updates are delivered over TLS 1.2-secured channels, and version history is retained for traceability. Integration with LIMS is supported via HL7 or ASTM E1384-compliant ASCII message exchange.

Applications

• Comparative dissolution profiling for generic drug bioequivalence studies per FDA Guidance for Industry (2013).
• Stability-indicating dissolution method development under ICH Q5C and Q1A(R2) frameworks.
• Excipient interaction screening during formulation optimization—particularly for pH-sensitive or polymorphic APIs.
• Batch release testing in accordance with pharmacopoeial monographs (USP, EP, ChP) for solid oral dosage forms.
• Investigational New Drug (IND) submission support, including dissolution robustness assessment across agitation rates, media composition, and surfactant concentrations.

FAQ

Does the DT08 support Apparatus 3 (reciprocating cylinder) or Apparatus 4 (flow-through cell)?
No—the DT08 is designed exclusively for USP Apparatus 1 and 2 configurations. Reciprocating or flow-through systems require separate hardware platforms.
Can audit trail data be exported in a reviewable format for regulatory inspection?
Yes—audit logs are exportable as PDF or CSV with digital signature metadata and can be archived in tamper-evident containers compliant with ALCOA+ principles.
Is the built-in printer capable of generating GLP-compliant raw data printouts?
Yes—the thermal printer produces permanent, non-erasable records containing instrument ID, operator ID, timestamp, method parameters, and real-time dissolution points—fully aligned with OECD GLP Principles Section 1.2.12.
What is the validation support package included with the DT08?
Haosoo provides a full qualification kit: Installation Qualification (IQ) checklist, Operational Qualification (OQ) protocols for temperature uniformity, rotational speed accuracy, and mechanical stability, plus blank PQ templates adaptable to site-specific SOPs.
How is microbiological contamination mitigated beyond the UV module?
In addition to the 254 nm UV-C irradiation, the system includes a stainless-steel recirculation path with electropolished interior surfaces (Ra ≤ 0.4 µm), automatic drain-and-purge cycles between runs, and optional silver-ion impregnated filter housings for secondary barrier protection.
