Overview
The BOXUN BIC-300 Plant Growth Chamber is an engineered environmental simulation system designed for reproducible, long-term cultivation of photoperiod-sensitive biological specimens under tightly regulated temperature, humidity, and light conditions. It operates on a dual-mode air circulation principle—combining laminar horizontal airflow with vertical convection lift—to ensure spatial homogeneity across all shelf levels. The chamber integrates a high-efficiency, non-CFC refrigeration circuit with an internationally certified compressor, enabling stable thermal control from 0°C to 60°C in darkness and 10°C to 60°C under active illumination. Its microprocessor-based control architecture supports precise regulation of relative humidity (60–90% RH) via a fin-type electric heating humidifier paired with a large-capacity external water reservoir, minimizing manual intervention during extended experiments. Designed for compliance-driven research environments, the BIC-300 meets foundational requirements for GLP-aligned plant phenotyping, seed germination trials, photomorphogenesis studies, and microbial culture stabilization.
Key Features
- Tri-dimensional illumination system delivering uniform light distribution (0–15,000 lx, six-step programmable intensity) across all shelf planes
- Integrated refrigeration architecture with patented zero-energy auto-defrost cycle—eliminates thermal disturbance during defrosting and extends uninterrupted operational duration
- LCD interface with real-time display of setpoints and actual values for temperature, humidity, light intensity, and elapsed time; supports multi-segment programming (30 segments × 99 cycles)
- Double-layer insulated chamber with cold-rolled steel exterior, electrostatically sprayed finish, and mirror-polished stainless-steel interior; four fully adjustable stainless-steel shelves
- Dual-safety architecture: mechanical door lock plus over-temperature cut-off alarm; built-in self-diagnostic routines for refrigeration status and sensor integrity
- RS-485 serial interface compliant with Modbus RTU protocol for integration into centralized lab monitoring networks or third-party data loggers
- Power-loss recovery function: retains all user-defined parameters and resumes operation automatically after grid interruption or system reset
Sample Compatibility & Compliance
The BIC-300 accommodates a broad spectrum of biological samples including Arabidopsis thaliana seedlings, rice coleoptiles, fungal cultures (e.g., Aspergillus spp.), bacterial colonies on agar plates, and tissue explants requiring controlled photoperiods. Its internal dimensions (540 × 520 × 1100 mm) support standard growth trays (e.g., 12-well and 24-well formats) and stacked petri dish racks. While not certified to ISO 17025 or ASTM E1826 by default, the chamber’s deterministic control logic, traceable sensor calibration paths (via optional NIST-traceable humidity/temperature probes), and audit-ready parameter logging capability make it suitable for laboratories operating under GLP or internal QA frameworks. All electrical components comply with IEC 61010-1 safety standards; refrigerant selection conforms to Montreal Protocol Phase-Out schedules.
Software & Data Management
The BIC-300 does not include proprietary cloud software but provides native RS-485 communication for interoperability with industry-standard SCADA platforms (e.g., LabVIEW, Ignition, or custom Python-based acquisition scripts). Users may configure interval-based data polling for temperature, humidity, and illumination status at user-defined frequencies (1 s to 60 min resolution). Optional accessories—including thermal printer modules (supporting time-stamped trend curves) and GPRS-enabled SMS alert transceivers—extend remote observability without requiring local network infrastructure. For regulatory environments, raw serial output can be parsed and archived in CSV or SQLite format, supporting retrospective review and 21 CFR Part 11-compliant electronic record workflows when deployed with validated timestamping and user-access controls.
Applications
- Controlled-environment plant physiology: photoperiod response assays, vernalization studies, and stress-induced morphological screening
- Microbial preservation and viability testing under defined hygrothermal-light regimes
- Seed dormancy and germination kinetics under standardized climate profiles per ISTA guidelines
- Pre-acclimation protocols for tissue-cultured plantlets prior to greenhouse transfer
- Long-duration stability testing of biologics and enzyme formulations sensitive to ambient fluctuations
- Educational laboratory use in undergraduate botany, microbiology, and environmental science curricula
FAQ
What is the maximum load capacity per shelf?
Each stainless-steel shelf supports up to 15 kg uniformly distributed load; total chamber loading must remain below 60 kg to maintain airflow integrity and thermal uniformity.
Can the BIC-300 operate continuously for 30 days without maintenance?
Yes—when filled with distilled water and operated within specified ambient conditions (15–30°C room temperature, ≤70% RH), the external water tank enables unattended humidification for ≥120 hours; compressor duty cycle remains within manufacturer-recommended limits under continuous 24/7 operation.
Is the illumination spectrum tunable beyond intensity adjustment?
No—the BIC-300 uses fixed-spectrum white LED arrays optimized for photosynthetically active radiation (PAR); spectral composition is not variable. For wavelength-specific studies, users should integrate external monochromatic light sources via the 60-mm outer-diameter top access port.
Does the unit support validation documentation (IQ/OQ/PQ)?
The base configuration includes factory calibration certificates for temperature and humidity sensors. Full IQ/OQ/PQ protocols require third-party validation services; BOXUN provides technical drawings, electrical schematics, and firmware revision logs upon request to facilitate qualification activities.
How is temperature uniformity verified across shelf levels?
Uniformity is characterized per ISO 16730 Annex A using nine-point mapping (3×3 grid per shelf) at 25°C and 37°C setpoints; deviation remains within ±1°C across all designated test points, as confirmed in出厂 calibration reports.
