Labonce Labonce-2000BI Biochemical Incubator

Overview

The Labonce Labonce-2000BI Biochemical Incubator is a high-capacity, precision-controlled environmental chamber engineered for stable, reproducible temperature maintenance across life science and quality control laboratories. Designed according to GB/T 28851-2012 technical specifications for biochemical incubators, it employs forced-air convection via an optimized ducted airflow system to ensure uniform thermal distribution throughout its 2000 L working volume. Its operational range spans 0–60°C—covering standard mesophilic culture conditions (e.g., 37°C mammalian cell growth), low-temperature enzymatic assays, and ambient-to-moderate thermophilic applications. The unit integrates industrial-grade refrigeration, corrosion-resistant construction, and fail-safe thermal management to support long-term unattended operation in regulated environments including GLP-compliant QC labs, pharmaceutical stability testing, and academic microbiology research.

Key Features

• High-capacity chamber (2000 L) with internal dimensions of 1500 × 970 × 1400 mm (W×D×H), accommodating large-scale cultures, multi-tier shelving, or stacked sample containers.
• Uniform temperature distribution: ≤2.0°C deviation at 37°C and ≤3.0°C across the full operating range—validated per GB/T 28851-2012 spatial uniformity protocols.
• Dual-layer thermal insulation combined with an imported hermetic industrial compressor delivers stable cooling performance with low acoustic emission (<55 dB(A)) and extended service life under continuous duty cycles.
• Electropolished AISI 304 stainless-steel interior—non-porous, non-shedding, and compatible with ethanol, hydrogen peroxide vapor (HPV), and routine laboratory disinfectants—ensures bioburden control and simplifies cleaning validation.
• LCD-based microprocessor controller with real-time display of setpoint, actual temperature, fan speed, and alarm status; fan speed is continuously adjustable to balance uniformity, recovery time, and condensation risk.
• Integrated safety architecture: independent mechanical over-temperature cut-off (separate from main controller), compressor thermal/pressure interlocks, and local audible alarm with visual indicator.

Sample Compatibility & Compliance

The Labonce-2000BI supports diverse sample formats—including Petri dishes, flasks, roller bottles, multiwell plates, and custom bioreactor vessels—without compromising thermal homogeneity. Its fully sealed, smooth-welded stainless-steel chamber eliminates crevices where microbial accumulation may occur, meeting hygiene requirements for ISO 14644-1 Class 8 cleanroom-adjacent use. All electrical and thermal subsystems comply with GB/T 28851-2012 mechanical, safety, and performance criteria. Optional UV-C germicidal irradiation (254 nm) and SMS-based remote alarm modules enable enhanced biosafety monitoring. While not certified to IEC 61000-6-3 (EMC) or UL 61010-1 out-of-the-box, the unit’s design permits third-party assessment for regional regulatory alignment upon request.

Software & Data Management

Data integrity is maintained through dual-path logging: (1) onboard non-volatile memory stores timestamped temperature readings at user-defined intervals (1–60 min), and (2) a built-in thermal dot-matrix printer provides immediate hard-copy audit trails. Export is supported via standard USB-A interface—data files conform to CSV format with ISO 8601 timestamps, enabling direct import into LIMS, ELN, or statistical analysis platforms (e.g., JMP, Python pandas). Optional BIT-series touch controller upgrade adds role-based access control (three-tier permissions), electronic signatures, and FDA 21 CFR Part 11–compliant audit trail generation—including operator ID, parameter changes, and event timestamps—suitable for GMP-regulated workflows.

Applications

• Bacterial and fungal cultivation in environmental monitoring, food safety, and clinical microbiology labs.
• Long-duration stability studies for APIs and finished pharmaceutical products per ICH Q1 guidelines.
• Enzyme kinetics and protein expression assays requiring precise sub-ambient or elevated temperature control.
• Seed germination, plant tissue culture, and aquatic organism rearing in agricultural and ecological research.
• Calibration verification of temperature-sensitive sensors and reference standards in metrology labs.

FAQ

What is the minimum and maximum operating temperature range?
The Labonce-2000BI maintains temperatures from 0°C to +60°C, with stability verified across the entire span.
Does the incubator support humidity control?
Standard configuration does not include active humidification; optional humidity sensing module is available as an add-on—but no integrated humidifier is provided.
Can the unit be validated for IQ/OQ/PQ protocols?
Yes—its documented thermal performance, traceable sensor calibration points, and consistent airflow profile support formal qualification under ISO/IEC 17025 or ASTM E2875-13 frameworks.
Is remote monitoring possible without the optional BIT controller?
Basic remote status readout (e.g., temperature, alarm state) can be achieved via RS-485 Modbus RTU interface; full telemetry and control require the BIT upgrade.
What power supply requirements must be met for installation?
A dedicated 220 V ±10%, 50 Hz circuit rated for ≥16 A continuous load is required; grounding resistance must be <4 Ω per GB 50169.
