Labonce Labonce-250TH-T Drug Stability Testing Chamber

Overview

The Labonce Labonce-250TH-T Drug Stability Testing Chamber is a purpose-built environmental simulation system engineered for long-term stability studies in compliance with ICH Q1, Q5C, and regional pharmacopoeial requirements (e.g., USP & EP chapters on stability testing). It operates on the principle of forced-air convection combined with precision-controlled refrigeration, heating, and humidification subsystems to maintain highly reproducible temperature and relative humidity conditions across its 250 L internal chamber volume. Designed specifically for pharmaceutical quality control laboratories, R&D departments, and contract research organizations (CROs), this chamber supports real-time monitoring of physical and chemical degradation pathways—including hydrolysis, oxidation, and polymorphic transitions—under defined storage conditions (e.g., 25 °C/60 %RH, 30 °C/65 %RH, or accelerated 40 °C/75 %RH protocols).

Key Features

• Advanced air distribution system ensuring temperature uniformity ≤2.0 °C and humidity uniformity ≤3.0 %RH across the entire working space, validated per ISO 16770:2017 guidelines for stability chambers.
• High-density polyurethane foam insulation (≥100 mm thick) with seamless foaming process, minimizing thermal bridging and reducing energy consumption by up to 18% compared to conventional designs.
• Corrosion-resistant interior constructed entirely from mirror-finish AISI 304 stainless steel; exterior finished with electrostatic powder coating over cold-rolled steel for durability and cleanroom compatibility.
• Hermetically sealed, high-efficiency scroll-type compressor (imported) paired with microchannel condenser and capillary tube expansion system—optimized for continuous operation at elevated humidity levels without frosting or performance drift.
• Large-format 7-inch color TFT touchscreen controller supporting up to 99 programmable segments, ramp/soak profiles, and real-time deviation alarms with event logging.
• Capacitive humidity sensor (imported, high-temperature rated) with NIST-traceable calibration certificate; drift <±0.5 %RH/year, maintenance-free over 5 years under normal use.
• Dual independent safety layers: mechanical over-temperature cut-off (separate from main controller) and dry-run protection for humidifier, both triggering audible/visual alarm and automatic shutdown.

Sample Compatibility & Compliance

The Labonce-250TH-T accommodates standard pharmaceutical packaging formats—including blister packs, HDPE bottles, glass vials, and aluminum pouches—via adjustable stainless-steel shelving (3 standard positions, expandable to 7). All internal surfaces are non-outgassing and compliant with USP for plastic components. The chamber meets GB/T 10586–2006 technical specifications for damp heat test equipment and is designed to support validation activities aligned with FDA 21 CFR Part 11, EU Annex 15, and WHO TRS 992 Annex 5. IQ/OQ documentation templates and factory acceptance test (FAT) reports are available upon request. Optional qualification packages include mapping studies (per ISO 14644-3), uncertainty budgeting, and traceable calibration certificates for temperature and humidity sensors.

Software & Data Management

Data integrity is ensured through embedded electronic logging with time-stamped records for all setpoints, actual values, alarms, and operator actions. Raw data files (CSV format) can be exported via USB 2.0 interface with password-protected access and audit trail functionality—fully compliant with ALCOA+ principles. Optional Ethernet connectivity enables integration into laboratory information management systems (LIMS) or SCADA platforms using Modbus TCP protocol. For regulated environments, optional software modules provide electronic signatures, role-based user permissions, and 21 CFR Part 11-compliant electronic records with immutable audit trails.

Applications

• I CH Q1A(R3) long-term and accelerated stability testing of APIs and finished dosage forms
• Photostability assessment when integrated with optional UV/visible light modules (IEC 60068-2-5)
• Accelerated aging studies for packaging material compatibility (ASTM F1980)
• Real-time shelf-life determination for biologics, vaccines, and sterile products
• Environmental stress screening during formulation development
• GLP-compliant stability programs requiring full traceability and regulatory submission readiness

FAQ

What standards does the Labonce-250TH-T comply with for pharmaceutical stability testing?
It conforms to GB/T 10586–2006, supports ICH Q1 series protocols, and is configurable for compliance with USP , EP 2.2.45, and FDA guidance on stability testing.
Can the chamber perform cycling tests (e.g., temperature/humidity ramps)?
Yes—the programmable controller supports multi-segment ramp-and-soak profiles, including dynamic transitions between temperature and humidity setpoints per ICH Q1D.
Is remote monitoring supported out of the box?
Standard configuration includes local USB data export; Ethernet and cloud-based remote access require optional communication module installation.
What is the recommended calibration interval for temperature and humidity sensors?
Annual calibration is advised per ISO/IEC 17025 requirements; Labonce provides accredited calibration services with NIST-traceable certificates.
Are validation documents included with the system?
Factory acceptance test (FAT) report and IQ/OQ templates are supplied; full validation support (including PQ) is available as a professional service engagement.
