LOGAN SYSTEM 860DLA 12-Position Automated Sampling Dissolution System

Overview

The LOGAN SYSTEM 860DLA is a fully integrated, online 12-position automated dissolution sampling system engineered for regulatory-compliant pharmaceutical development and quality control. It operates on the USP Apparatus 1 (basket), Apparatus 2 (paddle), and extended methodologies including mini-vessel, rotating cylinder, paddle-over-disc, and flow-through cell configurations—enabling method flexibility across solid oral dosage forms (tablets, capsules), semi-solids (gels, patches), and suspensions. The system implements gravimetrically calibrated syringe-pump-driven sampling with real-time volumetric compensation, ensuring adherence to USP & Ph. Eur. dissolution protocol requirements. Its architecture supports continuous operation under GLP/GMP conditions, with temperature stability maintained within ±0.2 °C per vessel via individual Pt100 RTD sensors and dual-lid vessel sealing—minimizing solvent evaporation and thermal drift during prolonged runs (up to 24+ hours).

Key Features

• Simultaneous 12-vessel dissolution testing with independent parameter control (rotation speed, temperature, sampling timepoints)
• Dual-stage filtration: pre-sampling membrane filter (0.45 µm or 0.22 µm) and post-sampling inline filter to protect analytical instrumentation and ensure particulate-free samples
• SYP-12L-10 mL high-precision syringe pump delivering ±0.5% volumetric accuracy across 1–10 mL draw volumes, eliminating manual pipetting variability
• Integrated isothermal replenishment: maintains constant dissolution medium volume and temperature by replacing sampled volume with pre-warmed media at identical setpoint
• DSC-800 centralized controller with embedded Linux OS, 10.1″ capacitive touchscreen, and real-time graphical monitoring of all vessels (temperature, RPM, sampling status)
• Comprehensive data integrity framework: full electronic audit trail, time-stamped user actions, role-based three-tier permissions (Administrator, Supervisor, Analyst), and digital signature support aligned with FDA 21 CFR Part 11 Subpart B
• Modular scalability: optional add-ons include high-resolution dissolution imaging (12-channel synchronized camera module), UV/HPLC interface modules, fiber-optic probe integration, and permeation system coupling for dissolution-permeation correlation studies

Sample Compatibility & Compliance

The SYSTEM 860DLA accommodates standard USP-compliant dissolution vessels (100–1000 mL), as well as mini-vessels (5–50 mL) and flow-through cells when configured with appropriate accessories. It supports all major dosage forms: immediate- and extended-release tablets, hard/soft gelatin capsules, orally disintegrating tablets (ODTs), transdermal patches, buccal films, and hydrogel-based formulations. All hardware and firmware comply with ISO 9001 design controls, and software meets ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate). System validation documentation includes IQ/OQ/PQ protocols, traceable to NIST-calibrated standards. Full compliance with ICH Q5C (stability), Q7 (GMP), and Q8 (Pharmaceutical Development) is supported through configurable reporting templates.

Software & Data Management

LOGAN Dissolution Manager v5.x provides validated, 21 CFR Part 11-compliant software for method programming, run supervision, data acquisition, and report generation. It features automated calibration logging, instrument self-diagnostics, and export in PDF/A-2, CSV, and XML formats compatible with LIMS and ELN platforms. Audit trail records include operator ID, timestamp, parameter changes, sampling events, error logs, and electronic signatures—all immutable and exportable without modification. Remote monitoring is enabled via secure HTTPS web interface or dedicated iOS/Android application, allowing real-time status checks and alarm notifications without compromising network security (TLS 1.2+, firewall-compatible port configuration).

Applications

• Generic drug bioequivalence (BE) studies requiring high-precision, multi-timepoint dissolution profiling
• QbD-driven formulation development, including DoE-based parameter optimization (e.g., surfactant concentration vs. release kinetics)
• Comparative dissolution-permeation modeling using coupled PAMPA or Caco-2 modules to predict in vivo absorption
• Stability-indicating dissolution assays for accelerated and long-term stability programs
• Regulatory submission support: generation of complete, auditable datasets for ANDA, NDA, and MAA filings
• Automated QC release testing with pass/fail criteria based on multivariate statistical process control (SPC) limits

FAQ

Does the SYSTEM 860DLA support USP Apparatus 4 (flow-through cell)?

Yes—when equipped with the optional FTC-12 flow-through cell manifold and peristaltic drive module, the system executes laminar-flow dissolution testing per USP & JP standards.
Can sampling intervals be programmed independently per vessel?

No—sampling is synchronized across all 12 vessels within a single method; however, multiple methods can be queued sequentially with distinct timing profiles.
Is temperature calibration traceable to NIST?

Yes—each RTD probe is individually calibrated with NIST-traceable dry-block calibrators, and calibration certificates are stored within the system’s electronic record archive.
What data backup options are available?

Automated daily encrypted backups to internal SSD and network-mapped drives; optional cloud sync via secure SFTP with configurable retention policies.
Does the system support PAT (Process Analytical Technology) integration?

Yes—via analog/digital I/O ports and Modbus TCP, enabling real-time feed-forward control loops with UV, NIR, or Raman spectroscopic analyzers.
