Overview
The Distek 5100 Premiere Bath-Type Dissolution Testing System is a fully integrated, programmable platform engineered for precision-controlled dissolution testing in pharmaceutical quality control (QC), formulation development, and regulatory compliance laboratories. Utilizing a thermostatically regulated water bath architecture with independent vessel temperature monitoring and PID-controlled heating, the system maintains ±0.2 °C temperature stability across all 6 or 8 vessels (configurable), ensuring high reproducibility in accordance with United States Pharmacopeia (USP) chapters Dissolution, Drug Release, and The Design and Development of Dissolution Test Methods. Unlike paddle-over-disk or flow-through cell systems, the 5100 Premiere employs classic basket (USP Apparatus 1) and paddle (USP Apparatus 2) configurations with mechanical drive shafts mounted on a rigid aluminum frame, minimizing vibration-induced variability during extended runtime protocols.
Key Features
- Modular bath-type design supporting up to eight dissolution vessels with individually calibrated temperature sensors and real-time digital display per vessel
- Programmable dissolution profiles including multi-stage rpm ramps, timed media additions, and automated sampling triggers
- Integrated motorized sampling arm with precise XYZ positioning, compatible with both fixed-loop and auto-sampling manifolds (e.g., Distek Auto-Sampler 2150 or third-party HPLC-integrated interfaces)
- Corrosion-resistant stainless-steel bath tank and vessel holders; compliant with ISO 9001-certified refurbishment standards
- Front-panel touchscreen interface with embedded firmware supporting method storage, audit trail logging, and password-protected user roles
- Pre-validated hardware architecture—no requalification required for routine USP-compliant testing when operated within specified environmental conditions (20–25 °C ambient, ≤60% RH)
Sample Compatibility & Compliance
The 5100 Premiere accommodates standard USP-compliant dissolution vessels (1000 mL, borosilicate glass), baskets (mesh size 20–40), and paddles (standard flat-blade or coated variants). It supports immediate-release (IR), extended-release (ER), and modified-release (MR) dosage forms—including tablets, capsules, granules, and transdermal patches—under sink or non-sink conditions. All refurbished units undergo full functional verification per ASTM E2503-21 “Standard Practice for Verification of Performance of Dissolution Apparatus” and include documented evidence of vessel alignment, rotational speed accuracy (±1 rpm at 50–200 rpm range), and temperature uniformity mapping. Systems are supplied with a Certificate of Conformance referencing USP , ISO 17025-aligned calibration records, and GLP-applicable maintenance logs.
Software & Data Management
While the 5100 Premiere operates autonomously via its onboard controller, it supports bidirectional RS-232/USB communication with Distek’s Dissolution Pro™ software (v5.3 or later) for advanced protocol scheduling, real-time curve visualization, and export of dissolution profiles in CSV, PDF, and XML formats. Audit trail functionality complies with FDA 21 CFR Part 11 requirements when paired with validated software installations, including electronic signatures, user access controls, and immutable event logging. Data integrity is preserved through automatic timestamping of all parameter changes, sampling events, and thermal deviations—enabling traceability during regulatory inspections or internal GMP audits.
Applications
This system is routinely deployed in pharmaceutical R&D labs for comparative dissolution profiling (BCS classification support), generic product development (ANDA submissions), stability-indicating method validation, and post-approval change evaluations (PQ/PQR studies). Its robust mechanical architecture and stable thermal environment also make it suitable for academic research involving polymer erosion kinetics, nanoparticle release modeling, and biorelevant media testing (e.g., FaSSIF/FeSSIF). Refurbished units retain full compatibility with legacy QC workflows and integrate seamlessly into existing LIMS environments via standard data exchange protocols.
FAQ
Is this unit compliant with current USP and FDA expectations for dissolution testing?
Yes—the 5100 Premiere meets the mechanical and operational specifications defined in USP , , and . All refurbished units include verification documentation aligned with ASTM E2503-21 and are supplied with a Certificate of Conformance.
What does the 6-month warranty cover?
The warranty covers parts and labor for defects in materials or workmanship under normal laboratory use, excluding consumables (vessels, baskets, paddles) and damage from improper installation, voltage fluctuations, or unauthorized modifications.
Can this system be integrated with HPLC autosamplers?
Yes—via optional analog/digital I/O modules or third-party interface kits, the 5100 Premiere can trigger external samplers or synchronize with HPLC injection sequences using TTL or relay-based signaling.
Are original manuals and calibration records included?
Yes—each unit ships with digitized copies of the original Distek Operation Manual, Preventive Maintenance Guide, and a complete refurbishment dossier including pre- and post-verification test reports.
Is remote technical support available after purchase?
Yes—SpectraLab Scientific provides post-sale engineering consultation, method troubleshooting, and on-site service coordination (fees apply beyond warranty scope).
