Overview
The ANDISSO T2400 PRO is a 24-position automated transdermal diffusion system engineered for precise, reproducible in vitro release testing (IVRT) and in vitro permeation testing (IVPT) of topical pharmaceuticals and dermocosmetic formulations. It operates on the Franz diffusion cell principle—a well-established hydrodynamic model that simulates passive transdermal transport across biological or synthetic membranes under controlled physiological conditions. The system complies fully with United States Pharmacopeia (USP) Chapter <1724> “In Vitro Release Testing for Transdermal Delivery Systems,” ensuring methodological rigor for regulatory submissions, formulation optimization, and quality control workflows. Its integrated dry-heating temperature control module maintains uniform thermal stability across all 24 stations (37 ± 0.5 °C), eliminating water-bath variability while reducing contamination risk and maintenance overhead.
Key Features
- 24 independent, parallel diffusion stations with synchronized sampling capability—enabling high-throughput screening of multiple formulations or time-point replicates in a single run.
- Dry-heating temperature regulation system: eliminates water-bath evaporation, condensation, and microbial growth concerns while delivering rapid thermal equilibration and ±0.3 °C stability over extended durations (≥24 h).
- Redesigned Franz-type diffusion cells with standardized donor compartment geometry (1.5–2.0 cm² effective diffusion area), optimized receptor volume (5–7 mL), and precision-machined PTFE gaskets to ensure leak-free operation and minimal dead volume.
- Automated liquid handling module featuring peristaltic pump-driven sampling, programmable volume selection (0.1–2.0 mL), and sequential/interval-based sampling schedules with integrated rinse cycles between withdrawals.
- Modular construction with ISO Class 5-compatible cleanroom-ready enclosure options and optional HEPA-filtered laminar airflow integration for GMP-aligned environments.
- Touchscreen HMI with embedded run log, real-time temperature monitoring per station, and alarm-triggered event logging compliant with ALCOA+ data integrity principles.
Sample Compatibility & Compliance
The T2400 PRO accommodates a broad range of sample formats including creams, ointments, gels, emulsions, sprays, patches (matrix and reservoir types), and cosmetic actives (e.g., retinoids, niacinamide, peptides). It supports both natural (excised human/porcine skin) and synthetic membranes (Strat-M®, Epiderm™, silicone, cellulose acetate) per USP <1724> recommendations. All hardware and operational protocols align with ICH Q5C (stability), ICH Q6A (specifications), and FDA guidance on IVRT method validation. System documentation includes IQ/OQ/PQ templates, traceable calibration records, and audit-ready electronic logs meeting 21 CFR Part 11 requirements when paired with validated software configurations.
Software & Data Management
The system operates via ANDISSO ControlSuite v3.2—a validated Windows-based application supporting full lifecycle data management. It enables method creation with multi-step temperature ramping, sampling sequence definition, auto-calculated cumulative release profiles (µg/cm²/h), and export to CSV, PDF, or XML formats. Audit trails record user actions, parameter changes, and instrument events with immutable timestamps. Data encryption, role-based access control (RBAC), and electronic signature support are implemented to satisfy GLP and GMP data governance standards. Integration with LIMS platforms (via ASTM E1384-compliant HL7 or ODBC) is available upon configuration.
Applications
- Regulatory method development and validation for ANDA, NDA, and MAA submissions targeting transdermal products.
- Comparative IVRT studies for generic product equivalence assessment per FDA Draft Guidance (2022).
- Formulation robustness evaluation—assessing impact of excipients, pH, viscosity, and surfactant concentration on drug flux and lag time.
- Stability-indicating release profiling during accelerated and long-term storage studies.
- Skin irritation and penetration depth modeling using radiolabeled or LC-MS/MS quantification endpoints.
- Non-pharmaceutical applications including sunscreen UV-filter release kinetics, anti-aging ingredient bioavailability screening, and preservative efficacy testing in leave-on cosmetics.
FAQ
Does the T2400 PRO meet USP <1724> dimensional and operational specifications for Franz cells?
Yes—the diffusion cell geometry, membrane clamping force, receptor volume tolerance, and agitation parameters conform strictly to USP <1724> Annex 1 requirements.
Can the system be qualified for use in GMP manufacturing environments?
Yes—when deployed with validated ControlSuite v3.2 and documented IQ/OQ/PQ protocols, it satisfies Annex 11 and PIC/S PE 009-16 expectations for computerized system validation.
Is third-party calibration certification available?
ANDISSO provides NIST-traceable calibration certificates for temperature sensors and volumetric dispensing modules, with annual recalibration services supported globally.
What membrane mounting accessories are included?
Standard kit includes stainless-steel clamps, PTFE gaskets (0.5 mm thickness), and membrane alignment fixtures compatible with 12 mm and 15 mm diameter membranes.
How is carryover minimized during automated sampling?
Each sampling line undergoes a three-stage rinse cycle (air flush → solvent purge → air dry) between withdrawals, with flow rate and dwell time programmable per method.
