Distek Dissolution Tester 6100

Overview

The Distek Dissolution Tester 6100 is a precision-engineered, benchtop dissolution testing system designed for compliance with USP <711>, <724>, and <1092>, as well as ISO 16856 and ASTM D7727 standards. It operates on the principle of controlled fluid hydrodynamics—employing either basket (USP Apparatus 1) or paddle (USP Apparatus 2) methodology—to quantitatively assess the rate and extent of drug substance release from solid oral dosage forms under physiologically relevant conditions. The system integrates a thermostatically regulated water bath, programmable rotational mechanics, and real-time environmental monitoring to deliver high reproducibility across batch-to-batch and lab-to-lab studies. Its modular architecture supports both routine QC workflows and complex method development protocols in pharmaceutical R&D, regulatory filing support, and stability testing environments.

Key Features

• Full-color, high-resolution touchscreen interface with intuitive graphical navigation—enabling rapid method setup, real-time parameter monitoring, and error-free operation after minimal operator training.
• Tool-free, auto-height-adjusting shaft mechanism: eliminates manual recalibration when switching between basket and paddle configurations, ensuring consistent immersion depth per USP requirements.
• Integrated Thermostatic Circulation System (TCS): microprocessor-controlled self-priming heater-circulator with low-profile, rear-mounted design—minimizing mechanical coupling to vessel assembly and reducing vibration-induced measurement noise.
• Scheduled wake/sleep mode: programmable start/stop timing for water bath activation—reducing energy consumption and extending thermal system longevity without compromising experimental readiness.
• Electronic validation reminder: configurable alerts for scheduled performance verification (PV), mechanical calibration, and preventative maintenance—supporting GLP/GMP documentation integrity and audit readiness.
• Optional Automated Drug Delivery System (DDS): precise, syringe-pump-based dosing synchronized with dissolution timepoints—enabling zero-time-point addition and multi-stage release profiling.

Sample Compatibility & Compliance

The 6100 accommodates standard USP-compliant vessels (100–4000 mL capacity) and supports interchangeable apparatus types—including baskets (10–12 mm mesh), paddles (flat or coated), and optional sinkers or flow-through cells (Apparatus 4). Its six-position base allows parallel testing under identical environmental conditions; upgrade kits extend capacity to seven or eight vessels. All temperature and rotational parameters meet or exceed USP <711> accuracy tolerances (±0.2 °C, ±0.2 rpm). The system is fully compatible with third-party UV/Vis spectrophotometers and HPLC autosamplers via analog/digital I/O interfaces. Data acquisition and instrument control comply with FDA 21 CFR Part 11 requirements when paired with validated software platforms supporting electronic signatures, audit trails, and role-based access control.

Software & Data Management

The 6100 operates natively with Distek’s Evolution™ software suite (v5.0+), which provides comprehensive method definition, real-time graphing, statistical analysis (e.g., f₂ similarity factor calculation), and automated report generation in PDF or CSV format. Up to 100 preconfigured methods may be stored onboard; 50 distinct user accounts support hierarchical permissions (e.g., operator, supervisor, administrator). All experimental runs—including timestamps, parameter logs, and environmental deviations—are automatically archived with full traceability. Raw data files are structured in vendor-neutral formats (e.g., .CSV, .XML) to facilitate integration into LIMS or ELN systems. Optional 21 CFR Part 11 add-ons enable electronic signature enforcement, immutable audit trails, and secure data export—meeting global regulatory submission expectations.

Applications

• Quality control release testing of tablets, capsules, and modified-release formulations per pharmacopeial monographs.
• Comparative dissolution profiling for generic product development and bioequivalence assessment.
• Stability-indicating method development under stressed conditions (pH, surfactants, enzymes).
• Excipient interaction screening and formulation optimization during preclinical and clinical stages.
• Regulatory dossier preparation requiring documented instrument qualification (IQ/OQ/PQ) and ongoing performance verification.

FAQ

Is the Distek 6100 compliant with current USP and FDA requirements?
Yes—the system meets all mechanical calibration, temperature uniformity, and rotational accuracy specifications outlined in USP <711>, <724>, and FDA Guidance for Industry on Dissolution Testing of Immediate-Release Solid Oral Dosage Forms.

Can the 6100 be integrated into an existing laboratory network or LIMS?
Yes—via Ethernet or RS-232, it supports Modbus TCP and ASCII command protocols for bidirectional communication with external data systems and process controllers.

What documentation is provided with a refurbished unit?
Each unit ships with a full Factory Reconditioning Certificate, updated IQ/OQ protocols, calibration records traceable to NIST standards, and a 12-month limited warranty covering parts and labor.

Does the system support non-USP apparatus configurations?
Yes—custom fixtures for reciprocating cylinder (Apparatus 3), flow-through cell (Apparatus 4), and rotating disk (Apparatus 5/6) are available as validated accessories through Distek’s OEM engineering group.
