Labonce Labonce-500BI Biochemical Incubator

Overview

The Labonce Labonce-500BI Biochemical Incubator is a precision-engineered environmental chamber designed for stable, uniform temperature control in life science laboratories conducting microbiological assays, cell culture maintenance, biochemical reaction studies, enzyme activity profiling, and quality control testing of pharmaceuticals and food products. It operates on a forced-air convection principle, utilizing an optimized air circulation system to ensure minimal thermal gradients across the entire 500-liter working volume. The incubator complies with GB/T 28851–2012 “Technical Specifications for Biochemical Incubators”, and its mechanical and control architecture supports long-term operational stability under continuous 24/7 usage conditions typical of QC labs and academic core facilities.

Key Features

• High-fidelity temperature regulation: Achieves ±0.5°C fluctuation at elevated setpoints (e.g., 37°C) and ±1.0°C at lower ranges, with uniformity ≤2.0°C at 37°C — validated per ISO 15223-1 and aligned with USP environmental chamber performance criteria.
• Robust thermal enclosure: Mirror-polished AISI 304 stainless-steel interior eliminates crevices, prevents microbial retention, and withstands repeated disinfection with ethanol, hydrogen peroxide vapor, or quaternary ammonium compounds.
• Industrial-grade refrigeration: Hermetically sealed, low-noise compressor delivers consistent cooling capacity across the full 0–60°C operating range, enabling reliable sub-ambient stabilization without condensation buildup or thermal shock to samples.
• Intuitive human-machine interface: Backlit LCD controller supports real-time parameter monitoring, programmable ramp-soak profiles, and manual fan-speed adjustment to balance airflow velocity against sample desiccation risk.
• Dual-path data integrity: Integrated thermal printer provides immediate hard-copy records of temperature logs; internal flash memory stores ≥30 days of 1-minute interval data, exportable via USB to external drives for GLP-compliant archiving.
• Multi-layer safety architecture: Includes redundant thermal fuses, compressor high-pressure cut-off, and independently wired over-temperature limiter — all triggering local audible alarms and visual fault indicators per IEC 61010-1 safety requirements.

Sample Compatibility & Compliance

The Labonce-500BI accommodates standard laboratory vessels including Petri dishes, multi-well plates (6–96-well), Erlenmeyer flasks (up to 2 L), and tissue culture roller bottles. Its 680 × 680 × 1080 mm chamber permits flexible shelving configuration (4 fixed-height support rails, 11 total shelf positions) and includes a front-access test port (Φ50 mm) for external sensor integration or gas line feedthrough. The unit meets electromagnetic compatibility standards (GB/T 18268.1), conforms to Class II equipment classification per GB 4793.1, and supports regulatory readiness for ISO/IEC 17025-accredited laboratories through traceable calibration documentation and configurable alarm thresholds.

Software & Data Management

While the base model employs embedded firmware without cloud connectivity, its USB-exported CSV-formatted log files are compatible with common laboratory information management systems (LIMS) and statistical process control (SPC) platforms such as JMP, Minitab, and LabWare. Optional BIT-series touch-screen controllers upgrade functionality to include role-based access control (administrator, operator, reviewer), electronic signatures, and FDA 21 CFR Part 11–compliant audit trails — capturing timestamped records of all parameter changes, alarm events, and user logins. All data exports retain metadata including instrument ID, firmware version, and calibration certificate expiry dates.

Applications

This incubator serves critical roles in environmental monitoring (e.g., BOD5 testing per APHA Standard Methods 5210B), clinical microbiology (coliform enumeration, fungal isolation), biopharmaceutical stability studies (ICH Q1A–Q1E), agricultural seed germination trials, and academic research involving thermosensitive protein expression systems. Its wide temperature span (0–60°C) enables both psychrophilic bacterial cultivation and accelerated degradation testing of diagnostic reagents — supporting method validation protocols required by CLIA, CAP, and CNAS accreditation bodies.

FAQ

What is the maximum load capacity per shelf?
Each adjustable stainless-steel shelf supports up to 15 kg uniformly distributed load; total chamber loading must not obstruct rear air inlet or top exhaust grilles.
Can the incubator operate continuously at 4°C?
Yes — the compressor-based cooling system maintains stable operation at 4°C for extended periods, provided ambient temperature remains ≤30°C and relative humidity is below 80% RH.
Is third-party calibration certification available?
Labonce provides NIST-traceable calibration reports upon request, covering temperature uniformity, fluctuation, and sensor accuracy at three points (low/mid/high) across the operating range.
Does the unit meet GMP requirements for pharmaceutical manufacturing?
When equipped with the BIT controller and operated under documented SOPs, the Labonce-500BI satisfies Annex 11 (EU GMP) and FDA guidance for automated system validation, including alarm response verification and data integrity controls.
How often does the UV lamp require replacement if installed as an option?
The optional 254 nm germicidal UV-C lamp has a rated service life of 8,000 hours; intensity decay is monitored via integrated radiometer feedback in BIT-equipped units.
