ALISN MPC 460 Pharmaceutical Refrigerated Stability Chamber

Overview

The ALISN MPC 460 Pharmaceutical Refrigerated Stability Chamber is an engineered environmental test system designed specifically for long-term, low-temperature stability studies of temperature-sensitive pharmaceutical products—including biologics, vaccines, sterile injectables, diagnostic reagents, and reference standards—under regulatory-compliant conditions. It operates on a precisely controlled refrigeration cycle based on variable-speed compressor technology and high-efficiency heat exchange architecture, maintaining the ICH-recommended storage condition of 5 ± 2°C with exceptional thermal stability and spatial uniformity. Unlike general-purpose cold rooms or laboratory refrigerators, the MPC 460 integrates hardware-level data integrity safeguards—including write-once logging, cryptographic timestamping, and immutable audit trails—ensuring full traceability for regulatory submissions and internal quality audits.

Key Features

• Advanced PID-fuzzy hybrid control algorithm enabling ±0.1°C temperature accuracy and ≤1.0°C intra-chamber uniformity across the 460 L working volume
• SECOP (Danfoss Group) hermetic compressor paired with EBM axial-flow condenser fan and R404a refrigerant for stable, low-noise, energy-efficient operation
• Monolithic polyurethane insulation (≥120 mm thickness) applied via one-shot foaming process, delivering >40% lower energy consumption versus conventional chambers of equivalent capacity
• 7-inch full-color capacitive touchscreen interface with intuitive icon-driven navigation, bilingual (English/Chinese) menu system, and real-time graphical display of temperature/humidity trends
• Multi-point temperature calibration function allowing independent offset correction at up to six sensor locations to compensate for thermal gradients
• Dual-door structure: outer door with magnetic seal and inner tempered glass door for visual monitoring without compromising thermal integrity
• Integrated 50 mm silicone-gasketed port on right side wall for probe insertion, tubing feedthrough, or external sensor integration

Sample Compatibility & Compliance

The MPC 460 accommodates standard ISO/IEC 17025-compliant stability sample configurations—including stacked trays, vial racks, ampoule holders, and multi-layer shelving (standard: two stainless-steel shelves; optional: three). Its interior chamber (750 × 1105 × 560 mm) supports ICH Q5C freeze-thaw cycle compatibility when operated in extended-range mode (up to +65°C, optional firmware activation). The system meets functional requirements for compliance with ICH Q1A(R2), Q1B, Q5C, USP “Stability Testing of Drug Substances and Products”, and WHO TRS No. 953 Annex 2. All data generation and storage mechanisms align with FDA 21 CFR Part 11 Subpart B (electronic records and signatures) and EU Annex 11 principles, supporting computerized system validation (CSV) under GxP environments.

Software & Data Management

Data acquisition occurs at one-minute intervals by default, storing raw temperature and humidity values (±0.1°C resolution) for up to three years in non-volatile memory. Logs are stored in encrypted binary format and exported only via USB mass-storage device as read-only CSV files—no modification or deletion is possible post-recording. The embedded audit trail captures user login/logout events, parameter changes, alarm triggers (e.g., door-open, over-temperature, sensor fault), and system resets with timestamps, user ID, and action context. System-level permission management allows administrators to assign five distinct roles (e.g., Operator, Supervisor, QA Reviewer, Calibration Technician, Administrator), each with granular access rights to settings, reports, and configuration menus.

Applications

• ICH-aligned accelerated and long-term stability testing of drug substances and products at 5 ± 2°C
• Real-time storage simulation for cold-chain logistics qualification (e.g., distribution mapping, packaging validation)
• Reference standard preservation under pharmacopoeial storage conditions (e.g., USP, EP, JP)
• Biological matrix storage for analytical method development and validation (e.g., plasma, serum, tissue homogenates)
• Environmental stress testing of diagnostic kits and in vitro diagnostic reagents
• Supporting GLP-compliant toxicology and pharmacokinetic study sample storage protocols

FAQ

What regulatory standards does the MPC 460 support for stability testing?

It is engineered to meet the operational and data integrity requirements of ICH Q1–Q5, USP , FDA 21 CFR Part 11, and EU GMP Annex 11.
Can the system be validated for GxP use?

Yes—the MPC 460 provides IQ/OQ documentation templates, DQ support files, and built-in tools for temperature mapping, alarm verification, and electronic signature readiness.
Is remote monitoring supported?

While no native Ethernet or cloud interface is included, RS232/RS485 ports enable integration with third-party SCADA or building management systems via Modbus RTU protocol.
How is data integrity ensured during power failure?

All logged data and audit events reside in battery-backed non-volatile memory; system resumes prior operating state automatically after power recovery, with no data loss.
Does the chamber support humidity control?

The MPC 460 is optimized for refrigerated stability at 2–8°C and does not include active humidification or dehumidification modules; relative humidity is passively maintained between 30–70% RH under standard ambient conditions.
