Agilent 708-DS Dissolution Tester

Overview

The Agilent 708-DS Dissolution Tester is a precision-engineered, modular platform designed for regulatory-compliant oral solid dosage form testing in pharmaceutical development, quality control, and stability studies. Based on the hydrodynamic principles of USP Apparatus 1 (basket), 2 (paddle), 5 (reciprocating disk), and 6 (cylindrical), the 708-DS delivers high mechanical reproducibility and minimal environmental interference—critical for method validation and routine QC workflows. Its robust architecture integrates thermal stability, precise rotational control, and positional accuracy to meet stringent performance verification requirements outlined in USP , , and ASTM E2503. As a fully import-grade instrument manufactured in the United States, the 708-DS supports global regulatory submissions and is routinely deployed in GLP- and GMP-aligned laboratories requiring audit-ready documentation and traceable mechanical qualification.

Key Features

• Multi-Apparatus Flexibility: Seamless configuration for USP Apparatus 1, 2, 5, and 6 using a shared upper shaft assembly—eliminating recalibration during method switching and ensuring consistent vessel-to-paddle/basket height alignment.
• TruAlign Vessel System: Patented dissolution vessels with embedded polymer collars guarantee repeatable centering and vertical alignment relative to the vessel plate; directional labels ensure orientation consistency across batches and operators.
• AutoTemp In-Vessel Monitoring: Real-time temperature measurement at each vessel location via optional handheld probe or integrated AutoTemp system—meeting USP temperature uniformity criteria (±0.2 °C).
• Automated Dosing & Sampling: Optional Drug Delivery Module (DDM) enables timed, sequential, or simultaneous dosing; compatible with 850-DS automated sampling workstations for unattended, multi-point kinetic profiling.
• Ergonomic Design: Motorized anti-evaporation lid lifts automatically during media addition, manual sampling, or physical parameter measurement; round-cornered water bath simplifies cleaning and reduces residual carryover.
• Compact Thermal Management: Rear-mounted heater/circulator—positioned beneath the vessel plate—minimizes benchtop footprint and incorporates vibration-dampening mounts to isolate mechanical noise from dissolution kinetics.
• Intuitive HMI: Full-color touchscreen interface supports English, Spanish, Japanese, and Simplified Chinese; password-protected screen lock ensures data integrity and operator accountability per 21 CFR Part 11 requirements.

Sample Compatibility & Compliance

The 708-DS accommodates standard USP-compliant dissolution vessels ranging from 100 mL to 2 L, supporting immediate-release, extended-release, and modified-release formulations. All configurations undergo Performance Verification Testing (PVT) per USP prior to deployment. The system meets ASTM E2503 mechanical qualification benchmarks—including wobble, centering, and verticality tolerances—and aligns with FDA’s enhanced Mechanical Qualification (MQ) guidance. It is validated for use in environments subject to ICH Q5A, Q5C, and WHO TRS 1019 compliance frameworks. Documentation packages include calibration records, PVT reports, and IQ/OQ templates suitable for internal audit and regulatory inspection.

Software & Data Management

The 708-DS operates natively with Agilent Dissolution Software (v3.x+), enabling synchronized control of up to four instruments from a single workstation. Data export supports CSV, PDF, and XML formats for integration into enterprise LIMS or electronic lab notebooks (ELN). Audit trail functionality logs all method changes, user actions, and system events with timestamps and operator IDs—fully compliant with 21 CFR Part 11 Annex 11 and EU GMP Annex 11 requirements. Optional secure remote monitoring via Ethernet allows real-time status checks without compromising network segmentation policies.

Applications

• Regulatory dissolution method development and validation per ICH Q4B and USP
• Comparative dissolution profiling for generic drug bioequivalence studies
• Stability-indicating release testing under accelerated and long-term storage conditions
• Excipient interaction screening and formulation robustness assessment
• Quality-by-Design (QbD) parameter space mapping for critical process attributes
• Support of ANDA, NDA, and MAA submissions with full traceability and raw data retention
