Labonce Labonce-720FT Precision Temperature and Humidity Controlled Stability Chamber

Overview

The Labonce Labonce-720FT is a high-precision, programmable temperature and humidity controlled stability chamber engineered for long-term pharmaceutical stability testing in compliance with international regulatory frameworks. Designed according to the principles of controlled environmental exposure, it maintains rigorously defined thermal and hygroscopic conditions across its 700 L working volume using dual-loop PID control architecture, high-efficiency refrigeration, and capacitive humidity sensing. Its operational envelope—0–70 °C and 10–80 %RH—is calibrated to meet ICH Q1A(R3) accelerated and long-term storage protocols, as well as the requirements outlined in the Chinese Pharmacopoeia (2020 Edition) for drug product shelf-life determination. The chamber’s structural integrity, thermal inertia management, and airflow distribution system are validated to ensure spatial uniformity and temporal stability—critical parameters for generating reproducible, audit-ready stability data under GLP and GMP environments.

Key Features

• Triple-tier user authentication system with role-based access control (RBAC), supporting at least three distinct permission levels (e.g., operator, supervisor, administrator) via username/password login.
• Auditable electronic record system compliant with FDA 21 CFR Part 11: full audit trail functionality—including timestamped operator actions, parameter changes, alarm events, and system logins—exportable to USB in tamper-evident, read-only formats (e.g., PDF/A or CSV with digital signature metadata).
• Triple-sided bottom air distribution design ensures laminar, low-velocity airflow across the entire chamber volume, minimizing thermal stratification and improving both temperature and humidity uniformity (±0.5 °C and <±2 %RH respectively).
• High-density polyurethane foam insulation (≥120 mm thick) with seamless foaming process delivers superior thermal resistance and moisture barrier performance, reducing energy consumption and enhancing chamber recovery after door openings.
• Double-door configuration: inner tempered glass door for non-intrusive visual monitoring; outer solid insulated door with magnetic seal to preserve internal conditions and block ambient light interference—critical for photolabile compound testing.
• Industrial-grade hermetic compressor (imported), paired with precision expansion valve and redundant pressure/temperature safety cutoffs (overheat, overpressure, phase loss, low refrigerant flow).
• Capacitive humidity sensor (original imported), factory-calibrated traceable to NIST standards, offering ±0.8 %RH accuracy, minimal drift (<0.5 %RH/year), and zero routine maintenance requirements.
• 7-inch full-color programmable touchscreen controller with intuitive GUI, multi-segment ramp-soak programming, real-time graphing, and built-in data logging (≥100,000 points).

Sample Compatibility & Compliance

The Labonce-720FT accommodates standard pharmaceutical packaging formats—including blister packs, HDPE bottles, vials, syringes, and secondary cartons—on four adjustable stainless-steel shelves (304 grade). Its interior chamber is constructed entirely from mirror-finish AISI 304 stainless steel with electropolished welds and radius-curved corners, eliminating crevices that could harbor microbial contamination or residue. External casing uses powder-coated cold-rolled steel for mechanical durability and corrosion resistance. All materials comply with USP , ISO 10993-5 (cytotoxicity), and EU Directive 2002/72/EC for food-contact safety. The system is pre-validated for IQ/OQ documentation support and fully compatible with GMP-compliant validation protocols per ASTM E2500 and Annex 15 (EU GMP). Environmental qualification includes mapping per ISO 14644-1 Class 8 cleanroom-equivalent particulate control during operation.

Software & Data Management

The integrated network-capable monitoring software (LabonceNet v3.x) provides centralized remote supervision of multiple chambers via Ethernet or Wi-Fi. It supports automated report generation (PDF/Excel), configurable alarm escalation (email/SMS), and secure HTTPS-based web interface accessible from validated browsers. Data integrity safeguards include automatic backup to NAS/cloud storage, write-protection on local SSD, and cryptographic hashing of all logged entries. Electronic signatures are implemented per 21 CFR Part 11 Subpart B requirements, including identity verification, intention-to-sign confirmation, and immutable linkage between signature and associated data set. Audit trails are retained for ≥30 years and searchable by event type, operator ID, time range, or parameter deviation threshold.

Applications

• ICH-guided stability studies: real-time (25 °C/60 %RH), accelerated (40 °C/75 %RH), intermediate (30 °C/65 %RH), and stress testing (e.g., 60 °C dry heat).
• Accelerated aging of medical device packaging per ISO 11607-1 and ASTM F1980.
• Biological sample preservation validation for biologics and mRNA formulations requiring strict RH control.
• Reference material storage under certified environmental conditions (ISO/IEC 17025 accredited labs).
• Material compatibility testing of primary and secondary packaging components (e.g., moisture vapor transmission rate correlation).
• Environmental stress screening of electronic components and sensors per MIL-STD-810G Method 502.6.

FAQ

Does the Labonce-720FT support 21 CFR Part 11 compliance out-of-the-box?
Yes—the system ships with preconfigured audit trail, electronic signature, and data integrity modules aligned with Subpart B requirements, including role-based permissions, immutable logs, and exportable tamper-proof records.
Can the chamber be qualified for GMP environments?
Yes—it includes comprehensive IQ/OQ documentation templates, mapping protocols, and calibration certificates traceable to national metrology institutes; final PQ must be performed per site-specific SOPs.
What is the maximum number of users supported in the RBAC system?
Up to 50 unique user accounts with customizable roles, password policies (expiry, complexity), and session timeout settings.
Is remote monitoring possible without installing additional hardware?
Yes—built-in Ethernet port and embedded web server enable browser-based access; no external gateway or PLC required.
How frequently does the humidity sensor require recalibration?
Under normal operation, annual recalibration is recommended; the capacitive sensor exhibits <0.5 %RH/year drift, and field verification can be performed using saturated salt solutions per ISO 4677.
