Labonce Labonce-1000BI Biochemical Incubator

Overview

The Labonce Labonce-1000BI Biochemical Incubator is a high-capacity, precision-controlled environmental chamber engineered for stable, reproducible temperature maintenance across life science laboratories, pharmaceutical QC facilities, clinical research units, and industrial microbiology labs. Designed in strict accordance with GB/T 28851-2012 (Technical Specifications for Biochemical Incubators), it employs forced-air convection via an optimized ducted airflow system to ensure minimal thermal gradient throughout its 1000 L working volume. The incubator operates within a calibrated range of 0–60°C—covering standard mesophilic culturing (e.g., E. coli at 37°C), psychrophilic studies, and enzyme activity assays—while maintaining ≤2.0°C uniformity at 37°C and ≤3.0°C across the full operating span. Its robust architecture integrates industrial-grade components—including a sealed imported compressor, corrosion-resistant AISI 304 stainless-steel interior, and powder-coated structural housing—to support long-term reliability under continuous operation in regulated environments.

Key Features

• Forced-air circulation system with variable-speed fan control ensures rapid temperature recovery (<15 min after 10°C door opening) and minimizes spatial deviation across the chamber.
• High-integrity chamber construction: Mirror-polished 304 stainless-steel inner walls eliminate crevices, prevent microbial retention, and enable validated cleaning protocols per ISO 14644 and EU GMP Annex 1 requirements.
• LCD-based microprocessor controller with real-time display of setpoint, actual temperature, fan speed, and elapsed run time; supports ramp-soak programming for multi-stage incubation protocols.
• Dual-level thermal safety architecture: Primary PID control loop plus independent mechanical over-temperature cutoff (adjustable up to 65°C), coupled with compressor thermal/pressure monitoring and audible local alarm.
• Integrated data management suite: Onboard non-volatile memory logs temperature readings at user-defined intervals (1–60 min); thermal printer provides hard-copy traceability; USB port enables secure export of CSV-formatted datasets for external analysis or regulatory submission.
• Ergonomic design elements include leveling casters with locking brakes, internal LED illumination, dual-layer observation window with anti-fog coating, and multiple 30-mm-diameter access ports for sensor feedthrough or gas line integration.

Sample Compatibility & Compliance

The Labonce-1000BI accommodates a broad spectrum of biological and biochemical samples—including Petri dishes, multi-well plates, flasks, bioreactor bags, and tissue culture vessels—without cross-contamination risk. Its seamless, weld-free interior and absence of painted or polymer-lined surfaces comply with ISO 13485 cleanroom compatibility expectations. The unit meets national standard GB/T 28851-2012 for temperature accuracy, uniformity, stability, and noise emission (<55 dB[A]). Optional UV-C germicidal irradiation (254 nm) and humidity monitoring modules extend functionality for applications requiring sterility assurance or hygrothermal correlation studies. When equipped with the BIT-series touchscreen controller (optional), the system supports ALCOA+ data integrity principles—including role-based access control (three permission tiers), electronic signatures, and immutable audit trails aligned with FDA 21 CFR Part 11 and EU Annex 11 requirements.

Software & Data Management

Data acquisition and reporting are managed through embedded firmware compliant with IEC 62304 Class B software safety standards. Temperature logs are timestamped with millisecond resolution and stored in cyclic memory (minimum 30 days at 1-min intervals). Exported USB files retain full metadata—including operator ID, session ID, calibration status flags, and environmental timestamps—facilitating integration into LIMS or ELN platforms. The optional BIT controller adds advanced features: configurable alarm escalation (email/SMS via GSM module), remote web-based monitoring (HTTPS-secured), and automated PDF report generation with digital signature embedding. All data handling routines undergo periodic verification per GLP Annex 5 and ISO/IEC 17025 clause 7.7.

Applications

• Microbial growth kinetics and antimicrobial susceptibility testing (AST) per CLSI M07/M100 guidelines.
• Biochemical assay development requiring tightly controlled thermal environments (e.g., LDH, amylase, or protease activity profiling).
• Environmental simulation for stability testing of diagnostic reagents and biologics per ICH Q1A(R3).
• Cell line expansion and primary cell maintenance where CO₂-independent conditions are preferred.
• Quality control of raw materials, intermediates, and finished products in food safety, veterinary diagnostics, and water microbiology labs.
• Long-duration BOD incubation and coliform enumeration per APHA Standard Methods 9215B and ISO 9308-1.

FAQ

What is the maximum allowable ambient temperature for continuous operation?
The Labonce-1000BI is rated for uninterrupted use in ambient conditions between +5°C and +35°C. Operation outside this range may compromise temperature stability and compressor service life.
Can the incubator be validated for IQ/OQ/PQ protocols?
Yes. The unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China) and includes documentation templates supporting GxP-compliant qualification. Sensor ports and data export capability facilitate third-party validation using thermocouple mapping and statistical process control tools.
Is the stainless-steel interior electropolished?
The inner chamber uses mechanically polished AISI 304 stainless steel meeting Ra ≤ 0.8 µm surface roughness—sufficient for routine cleaning validation but not equivalent to electropolished (Ra ≤ 0.3 µm) surfaces used in aseptic processing isolators.
Does the standard configuration include humidity control?
No. Humidity monitoring and active humidification are optional add-ons. The base model maintains ambient relative humidity only.
How many users can be assigned distinct access levels with the BIT controller?
The BIT controller supports up to 20 unique user accounts across three hierarchical roles: Administrator, Supervisor, and Operator—with granular permissions for parameter editing, data export, and alarm acknowledgment.
