Labonce Labonce-150FC Pharmaceutical Low-Temperature Stability Chamber

Overview

The Labonce Labonce-150FC Pharmaceutical Low-Temperature Stability Chamber is an engineered environmental test system designed specifically for long-term stability studies and cold-chain storage of temperature-sensitive pharmaceutical products under ICH Q5C and Q1A(R2) guidance. Operating at a controlled setpoint of –23 °C ±2 °C (nominal), the chamber employs a dual-stage forced-air circulation architecture with optimized laminar airflow distribution to maintain thermodynamic equilibrium across the entire working volume. Its core function is to replicate accelerated or real-time storage conditions required for regulatory submission packages—including shelf-life determination, excipient compatibility assessment, and freeze-thaw cycle validation—while ensuring full traceability and audit readiness per GLP and GDP principles.

Key Features

• High-efficiency hermetic industrial compressor with low-noise operation (25,000 hours MTBF), enabling uninterrupted 24/7 operation under continuous load.
• Uniform temperature distribution achieved through a proprietary air duct design validated per ISO 14644-3:2019 Annex B methodology; uniformity ≤2.0 °C across all defined test points per YY/T 0086–2020 Clause 6.3.2.
• Structural integrity ensured by 100 mm thick high-density polyurethane insulation (thermal conductivity ≤0.018 W/m·K), minimizing heat ingress and reducing energy consumption by up to 22% versus conventional cabinets.
• Corrosion-resistant interior constructed entirely from mirror-finish AISI 304 stainless steel (EN 10088-2), compliant with USP extractables testing requirements and eliminating particulate shedding during cleaning cycles.
• Programmable color touchscreen controller supporting multi-step ramp-soak profiles, real-time deviation monitoring, and electronic data logging with configurable sampling intervals (1 s to 60 min).
• Triple-tier access control (Operator / Supervisor / Administrator) with password protection, user activity audit trail, and encrypted local data storage meeting FDA 21 CFR Part 11 requirements for electronic records and signatures.
• Integrated safety architecture including compressor overheat shutdown, high-pressure cutout, door-open detection, and redundant temperature sensor validation.

Sample Compatibility & Compliance

The Labonce-150FC accommodates standard pharmaceutical packaging formats—including vials (2–50 mL), syringes, blister packs, and primary containers sealed under nitrogen or argon—without compromising thermal homogeneity. Its internal configuration supports ISO/IEC 17025-accredited laboratories conducting stability testing per ICH guidelines and national pharmacopoeial standards (e.g., USP , EP 2.2.45). The unit conforms to YY/T 0086–2020 for medical refrigeration equipment and incorporates design elements aligned with WHO Technical Report Series No. 961 Annex 9 (Good Distribution Practice). All firmware and calibration procedures are documented per ISO/IEC 17025:2017 Clause 7.8.2, with factory calibration certificates traceable to NIM (National Institute of Metrology, China).

Software & Data Management

Data acquisition and reporting are managed via the embedded Labonce ControlSuite™ firmware, which logs timestamped temperature readings from three independent Pt100 sensors (one master, two redundancy) at user-defined intervals. Raw data exports in CSV format include metadata fields such as operator ID, profile name, event flags (e.g., door open, alarm activation), and checksum verification. Optional integration with LIMS platforms is supported via Modbus TCP/IP or RS485 serial interface. For regulated environments, the system provides full electronic audit trail functionality—including record creation/modification timestamps, user attribution, and immutable log files—with optional digital signature support for final report generation.

Applications

• ICH Q5C-compliant stability studies for biologics, monoclonal antibodies, and mRNA-based therapeutics requiring ultra-low temperature preservation.
• Real-time and accelerated stability testing of lyophilized products stored at –25 °C to assess residual moisture migration and glass transition behavior.
• Reference standard storage for QC labs operating under ISO/IEC 17025 accreditation, where temperature deviation must remain within ±2.0 °C of nominal setpoint for ≥95% of measurement duration.
• Validation of cold chain logistics protocols, including thermal mapping of transport containers and qualification of warehouse freezer zones.
• Supporting GMP Annex 15 lifecycle management of qualified equipment, including IQ/OQ/PQ documentation templates and preventive maintenance scheduling tools.

FAQ

What regulatory standards does the Labonce-150FC meet for pharmaceutical use?

It complies with YY/T 0086–2020, aligns with ICH Q1A(R2) and Q5C stability testing principles, and supports compliance with USP , EU GMP Annex 15, and WHO TRS 961 Annex 9.
Is the temperature data electronically signed and audit-ready?

Yes—the controller supports 21 CFR Part 11-compliant electronic signatures, role-based permissions, and immutable audit trails with time-stamped user actions.
Can the chamber be integrated into a centralized laboratory monitoring system?

Yes—via Modbus TCP/IP or RS485, enabling remote supervision, alarm forwarding, and automated data ingestion into enterprise MES or SCADA platforms.
What is the validation support package included with purchase?

Factory calibration certificate (NIM-traceable), IQ/OQ protocol templates, thermal mapping guidance document, and optional on-site PQ execution by certified engineers.
Does the unit support automatic defrost without interrupting temperature control?

Yes—intelligent adaptive defrost logic activates only when frost accumulation exceeds threshold, maintaining chamber setpoint stability throughout the cycle.
