ALISN MPC 1000 Pharmaceutical Refrigerated Stability Chamber

Overview

The ALISN MPC 1000 Pharmaceutical Refrigerated Stability Chamber is an engineered solution for long-term, regulatory-compliant cold storage and stability testing of temperature-sensitive biopharmaceuticals, vaccines, clinical trial materials, and reference standards. Designed in accordance with ICH Q5C, Q1A(R2), and USP , the chamber maintains a tightly controlled 2–8 °C operating range—meeting the critical “5 °C ± 3 °C” requirement specified in pharmacopoeial guidelines (EP 2.2.42, JP 17, USP ) for refrigerated stability studies. Its core architecture integrates a high-efficiency inverter-driven SECOP compressor, EBM precision condenser fans, and monolithic polyurethane insulation (≥120 mm thickness), enabling stable thermal performance with minimal spatial deviation (±0.3–0.8 °C uniformity) and rapid recovery (<15 min to re-stabilize after 60-second door opening). The system operates under continuous monitoring logic compliant with FDA 21 CFR Part 11 Annex 11 principles, supporting GxP-aligned validation protocols including IQ/OQ/PQ.

Key Features

• Inverter-based refrigeration system delivering precise thermal control, energy savings (>40% vs. conventional units), and reduced mechanical wear.
• 7-inch full-color TFT touchscreen interface with intuitive menu navigation, bilingual (English/Chinese) language toggle, and real-time graphical display of temperature curves.
• Multi-point temperature calibration function—enabling independent offset correction at up to six internal sensor locations to eliminate linear drift across the chamber volume.
• Dual-door construction: outer door with magnetic seal and inner tempered glass door for non-intrusive visual monitoring without thermal disturbance.
• Integrated HERAEUS platinum resistance thermometers (Pt100) with traceable NIST-calibration capability and redundant sensor monitoring.
• Comprehensive safety suite: over-temperature/under-temperature alarms, door-open alert, compressor overpressure protection, leakage current cutoff, and sensor fault detection with automatic fail-safe shutdown.
• Front-access 50 mm silicone grommet port for external probe routing or environmental sensor integration.

Sample Compatibility & Compliance

The MPC 1000 accommodates diverse sample formats—including vials, syringes, trays, and stacked cartons—within its 1000 L stainless-steel interior (304 grade, electropolished finish). Its validated airflow design ensures uniform exposure across all shelf levels, satisfying ISO 14644-1 Class 8 cleanroom-compatible handling requirements when used in controlled environments. Regulatory alignment includes documented conformance to ASTM F2697-22 (performance criteria for pharmaceutical refrigerators), ICH stability testing conditions (Condition 2: 25 °C/60% RH and Condition 3: 5 °C ± 3 °C), and EU GDP Annex 9 cold chain verification protocols. All firmware and data management functions support ALCOA+ data integrity principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Software & Data Management

Embedded firmware provides native audit trail functionality storing ≥16,000 timestamped entries—including user logins, parameter changes, alarm events, and maintenance actions—with write-once-read-many (WORM) enforcement. Temperature and humidity logs (sampled every 2 minutes) are stored internally for ≥10 years and exported exclusively via encrypted USB drives in CSV format—preventing post-collection modification. The system supports electronic signature workflows and role-based access control (five distinct permission tiers: Administrator, Supervisor, Technician, Reviewer, Auditor). Optional integration with LIMS or SCADA platforms is enabled via RS232/RS485 Modbus RTU protocol, with optional Ethernet module available for remote monitoring and TLS-secured cloud synchronization.

Applications

• ICH-compliant accelerated and real-time stability studies for drug substances and products under refrigerated conditions.
• Long-term storage of monoclonal antibodies, viral vectors, mRNA-LNPs, and other thermolabile biologics requiring strict 2–8 °C integrity.
• Reference standard preservation in QC laboratories adhering to USP and ISO/IEC 17025:2017 requirements.
• Clinical trial supply chain staging—serving as a qualified intermediate holding unit prior to distribution.
• Vaccine cold chain qualification, including hold-time verification per WHO TRS 961 Annex 9.
• Environmental stress testing of packaging systems under controlled low-temperature cycling.

FAQ

Does the MPC 1000 support 21 CFR Part 11 compliance?
Yes—the system implements electronic signatures, audit trails with immutable timestamps, role-based access controls, and data export mechanisms meeting FDA 21 CFR Part 11 Subpart B technical requirements.
What is the validation support package included with the unit?
Each MPC 1000 ships with a Factory Acceptance Test (FAT) report, IQ/OQ protocol templates aligned with ASTM E2500-13, and a Certificate of Calibration for primary temperature sensors.
Can the chamber be integrated into an existing building management system (BMS)?
Yes—via RS485 Modbus RTU or optional Ethernet gateway, enabling real-time status polling, alarm forwarding, and centralized event logging.
Is remote monitoring available without additional hardware?
Remote access requires the optional Ethernet communication module; once installed, secure HTTPS-based web interface and SNMP trap support are enabled.
How is temperature uniformity verified during commissioning?
Uniformity mapping follows ISO 14644-3 Annex B methodology using nine calibrated Pt100 probes placed at defined geometric locations; results are documented in the OQ report.
