BOXUN BMJ-250 Mold Incubator

Overview

The BOXUN BMJ-250 Mold Incubator is a precision-engineered, forced-air, refrigerated incubation system designed specifically for controlled cultivation and maintenance of filamentous fungi, yeasts, and other moisture-tolerant microorganisms requiring stable thermal environments between 0 °C and 60 °C. Unlike general-purpose CO₂ or heated-only incubators, the BMJ-250 integrates a robust, low-GWP refrigeration module with intelligent airflow management—enabling reliable sub-ambient operation critical for mycological studies, BOD5 testing, environmental isolate preservation, and pharmaceutical stability assessments under non-sterile but contamination-controlled conditions. Its architecture conforms to fundamental requirements outlined in ISO 21527-1 (microbiological methods for molds and yeasts), ASTM D3273 (resistance to fungal growth), and supports GLP-compliant workflows where temperature traceability, reproducibility, and system integrity are essential.

Key Features

• Integrated refrigeration system with internationally certified compressor and zero-ozone-depletion refrigerant, meeting EU F-Gas Regulation and U.S. EPA SNAP program criteria;
• Proprietary multi-directional air duct design coupled with high-efficiency centrifugal circulation fan ensures uniform temperature distribution (±1 °C at 37 °C) across full 250 L chamber volume;
• Microprocessor-based controller with backlit LCD interface provides real-time display of setpoint, actual temperature, elapsed time, and alarm status; supports 10-segment, 99-cycle programmable ramp-soak profiles;
• Self-diagnostic firmware continuously monitors refrigeration performance, sensor integrity, and power stability; initiates audible/visual alerts upon deviation beyond user-defined thresholds;
• Independent fresh-air inlet valve (manually adjustable) enables controlled gas exchange without compromising thermal homogeneity—critical for aerobic mold propagation and long-term viability assays;
• Four-tier adjustable stainless-steel shelving system (mirror-polished 304 grade) allows flexible load configuration; reinforced cold-rolled steel outer casing with electrostatic epoxy coating ensures mechanical durability and corrosion resistance;
• RS-485 serial interface compliant with Modbus RTU protocol facilitates integration into centralized lab monitoring networks or third-party data acquisition systems;
• Non-energy-consuming adaptive defrost algorithm eliminates thermal perturbation during defrost cycles—preserving sample integrity during extended unattended operation.

Sample Compatibility & Compliance

The BMJ-250 accommodates standard Petri dishes (90–150 mm), slant tubes, multi-well plates, and Erlenmeyer flasks up to 2 L. Its sealed chamber design—combined with mechanical door lock and optional GPRS-enabled remote alerting—meets containment requirements for Biosafety Level 1 (BSL-1) fungal handling per CDC/NIH guidelines. While not humidity-controlled, its stable thermal environment aligns with methodologies described in USP , EP 2.6.12, and ISO 7218 for enumeration of molds and yeasts in food, water, and environmental samples. All electrical components comply with IEC 61010-1 safety standards; electromagnetic compatibility satisfies EN 61326-1.

Software & Data Management

The embedded controller logs timestamped temperature readings at user-selectable intervals (1–60 min) with onboard storage for ≥30 days of continuous data. Via RS-485, external software (e.g., LabVIEW, MATLAB, or BOXUN’s optional PC utility) can perform real-time graphing, export CSV-formatted datasets, and generate audit-ready reports compliant with FDA 21 CFR Part 11 when paired with electronic signature modules. Optional thermal printer support enables hard-copy curve recording for QA documentation. Power-interruption resilience ensures no loss of setpoints, programs, or historical logs—even after extended outages.

Applications

• Quantitative mycological analysis in municipal water treatment labs (e.g., detection of Aspergillus, Penicillium, Cladosporium per APHA Standard Methods 9260B);
• Biochemical Oxygen Demand (BOD₅) incubation at 20 °C per ISO 5815-1 and ASTM D5210;
• Cultivation of dermatophytes and opportunistic fungi in clinical microbiology reference labs;
• Seed germination and phytopathogen challenge studies in agricultural research;
• Stability testing of excipients and non-sterile dosage forms under accelerated conditions (ICH Q1A);
• Environmental monitoring of HVAC systems and cleanroom support areas per ISO 14644-1 Annex C.

FAQ

Does the BMJ-250 support humidity control?
No. This model is a temperature-controlled incubator only. For combined temp/humidity applications, consider BOXUN’s BHG series or third-party external humidification add-ons.
Is the RS-485 interface compatible with common SCADA platforms?
Yes—Modbus RTU implementation enables native integration with Ignition, Siemens Desigo, or Honeywell Experion systems using standard protocol drivers.
What validation documentation is provided?
Factory calibration certificate (NIST-traceable PT100 sensor), IQ/OQ templates, and FAT report are included. Full 3Q validation support available upon request.
Can the unit operate continuously for 30+ days?
Yes—designed for unattended 24/7 operation with redundant thermal protection, low-noise compressor cycling, and passive defrost architecture minimizing thermal drift.
Are spare parts and service available outside China?
Global technical support network covers North America, EU, and APAC regions; critical spares (controllers, sensors, compressors) maintained in regional distribution hubs.
