Labonce Labonce-500BC Pharmaceutical Refrigerated Storage Chamber

Overview

The Labonce Labonce-500BC Pharmaceutical Refrigerated Storage Chamber is a purpose-engineered environmental test chamber designed specifically for the long-term stability testing and cold-chain storage of temperature-sensitive pharmaceutical products, including biologics, vaccines, reference standards, and clinical trial materials. Operating within a tightly controlled range of 2–14°C—centered on the pharmacopeial standard of 5±2°C—the chamber employs a precision air-circulation architecture based on optimized laminar airflow distribution to maintain thermodynamic consistency across the entire 500 L working volume. Its measurement and control framework aligns with the thermal performance requirements defined in YY/T 0086–2020, the Chinese industry standard for medical refrigeration equipment, while its mechanical and software design principles reflect internationally recognized expectations for GxP-aligned storage environments—including those referenced in ICH Q5C, USP , and WHO Technical Report Series No. 961 (Annex 9).

Key Features

• Engineered air distribution system: A reconfigured ductwork layout ensures uniform airflow throughout the chamber cavity, minimizing thermal stratification and achieving ≤2.0°C temperature uniformity (measured per ISO 14644-3 methodology at nine standardized points).
• High-integrity thermal insulation: 80 mm thick high-density polyurethane foam (density ≥40 kg/m³) with zero ozone-depleting blowing agents provides sustained thermal resistance (R-value >3.5 m²·K/W), reducing energy consumption and mitigating humidity ingress.
• Pharmaceutical-grade interior: Seamless, electropolished 304 stainless steel inner chamber—non-porous, corrosion-resistant, and compliant with ISO 14644-1 Class 8 surface roughness requirements (<0.8 µm Ra)—ensures cleanability and eliminates leachable contaminants.
• Dual-redundancy safety architecture: Integrated compressor overheat detection, high-pressure cut-off switches, and real-time current monitoring prevent mechanical failure during extended unattended operation.
• Regulatory-ready control interface: 7-inch full-color capacitive touchscreen controller supports user-defined multi-step temperature profiles, event-triggered data capture, and audit-trail-enabled electronic record retention meeting FDA 21 CFR Part 11 and EU Annex 11 expectations.

Sample Compatibility & Compliance

The Labonce-500BC accommodates a wide variety of pharmaceutical sample formats—including vials, syringes, blister packs, stability chambers trays, and nested secondary packaging—without compromising thermal homogeneity. Its internal dimensions (680 × 680 × 1080 mm) support standard ICH-compliant shelf loading configurations, while four adjustable 304 stainless steel shelves (load capacity: 25 kg/shelf) allow flexible vertical spacing. All materials in contact with the storage environment comply with USP Class VI biocompatibility testing and ISO 10993-5 cytotoxicity screening. The unit is certified to YY/T 0086–2020 for medical refrigeration performance and undergoes factory calibration traceable to CNAS-accredited national metrology institutes.

Software & Data Management

The embedded controller records temperature at 1-minute intervals with automatic timestamping and stores ≥12 months of continuous data internally. Data export is supported via USB 2.0 (CSV format) or optional RS485 Modbus RTU protocol for integration into centralized laboratory information management systems (LIMS) or SCADA platforms. Role-based access control enforces three-tier permissions (Operator / Supervisor / Administrator), and all parameter modifications generate immutable audit logs—including user ID, timestamp, pre-change value, and post-change value. Optional needle-type micro-printer enables on-demand hard-copy generation of trend reports and alarm summaries for GLP/GMP documentation workflows.

Applications

• ICH Q1A–Q1E long-term and accelerated stability studies under 25°C/60% RH and 30°C/65% RH reference conditions (when used as auxiliary cold storage for control samples).
• Storage of temperature-critical reference standards and working standards per USP and Ph. Eur. 2.2.45.
• Cold-chain validation support for distribution qualification (e.g., shipping container mapping studies using external probe inputs via the standard 2×Φ25 mm test ports).
• QC/QA batch release hold storage where documented thermal history is required for regulatory submissions (e.g., NDA, MA, BLA dossiers).
• Biobanking of clinical trial biospecimens requiring stable 2–8°C preservation prior to cryogenic archiving.

FAQ

Does the Labonce-500BC meet FDA 21 CFR Part 11 requirements for electronic records?
Yes—the controller implements role-based authentication, electronic signatures, and immutable audit trails for all critical operations, satisfying core technical controls outlined in Part 11 Subpart B.
Can the unit operate continuously for 365 days per year?
Yes—it is rated for continuous duty cycle (IEC 60034-1), validated for uninterrupted operation under ambient conditions of +5 to +30°C, and equipped with redundant thermal protection circuits.
Is the temperature data export format compatible with common LIMS platforms?
Yes—CSV output is natively readable by Oracle Clinical, LabVantage, STARLIMS, and custom SQL-based systems; Modbus RTU integration enables real-time telemetry in industrial automation environments.
What is the calibration interval recommendation?
Annual recalibration against NIST-traceable references is recommended; the unit includes built-in sensor diagnostics and drift alerts to support proactive maintenance scheduling.
Are external temperature probes supported?
Yes—two standardized Φ25 mm test ports with silicone rubber plugs enable insertion of calibrated Pt100 or thermistor probes for independent verification or product-core monitoring.
