Boxun BMJ-160 Mold Incubator

Overview

The Boxun BMJ-160 Mold Incubator is a precision-engineered, microprocessor-controlled environmental chamber designed specifically for the reliable cultivation and maintenance of filamentous fungi, yeasts, and other moisture-tolerant microorganisms under stable, contamination-minimized conditions. Unlike general-purpose incubators, the BMJ-160 integrates a proprietary air circulation architecture—featuring an independently driven centrifugal blower and a uniquely engineered duct system—that ensures rapid thermal equilibration and exceptional spatial temperature homogeneity (±1°C at 37°C). Its operational range spans 0°C to 60°C with 0.1°C resolution and ±0.5°C stability, enabling both mesophilic mold propagation and low-temperature preservation protocols. The unit employs a high-efficiency, non-CFC refrigeration system anchored by an internationally certified compressor and an innovative passive auto-defrost mechanism that eliminates thermal disturbance during defrost cycles—a critical requirement for uninterrupted long-term fungal colony development.

Key Features

• Integrated refrigeration system with patented zero-energy auto-defrost technology, eliminating temperature drift during maintenance cycles
• Microprocessor-based LCD controller supporting up to 10 programmable temperature segments across 99 total cycles for complex incubation profiles
• Dual-layer insulation combined with cold-rolled steel exterior (electrostatically powder-coated) and mirror-finish 304 stainless steel interior for corrosion resistance and easy decontamination
• Adjustable shelving system (3 removable, load-rated stainless steel trays) with tool-free height repositioning for flexible sample arrangement
• Dedicated fresh-air intake module with manual on/off control to maintain optimal O₂ levels and prevent CO₂ accumulation in sealed operation
• Robust safety architecture including over-temperature cut-off, mechanical door lock, real-time self-diagnostic checks, and non-volatile memory for parameter retention during power interruption
• RS-485 serial interface compliant with Modbus RTU protocol for integration into centralized lab monitoring networks or LIMS environments

Sample Compatibility & Compliance

The BMJ-160 is validated for use with standard microbiological culture formats including Petri dishes (90 mm and 150 mm), slant tubes, broth cultures, and agar plates. Its uniform thermal field supports ISO 21528-2:2017 (microbiological methods for food and animal feeding stuffs), ASTM D3273 (mold resistance testing of interior coatings), and USP / microbial limits testing workflows. While not a humidity-controlled chamber, its sealed design and optional fresh-air modulation make it suitable for aerobic mold isolation per CLSI M38-A3 guidelines. All electrical components meet IEC 61010-1 safety standards; refrigerant complies with Montreal Protocol phase-out requirements (R134a or equivalent).

Software & Data Management

The embedded controller logs temperature setpoints, actual readings, alarm events, and runtime status with timestamped records stored in internal non-volatile memory (retains ≥30 days of 1-minute interval data). Via the RS-485 port, users may deploy third-party SCADA or laboratory informatics platforms (e.g., LabArchives, LabVantage) to extract time-series datasets, generate audit trails, and enforce 21 CFR Part 11-compliant electronic signatures when paired with validated software layers. Optional thermal printer output provides hard-copy verification of incubation curves—essential for GLP/GMP documentation packages.

Applications

• Primary isolation and subculturing of Aspergillus, Penicillium, Cladosporium, and other clinically or environmentally relevant molds
• BOD₅ and wastewater toxicity assays requiring standardized fungal bioassays (e.g., ISO 8192)
• Pharmaceutical stability testing of excipients susceptible to fungal degradation
• Agricultural mycology studies—including spore germination kinetics and antifungal susceptibility screening (CLSI M38-A3)
• Quality control of sterile medical devices and packaging materials per AAMI ST72
• Environmental monitoring of indoor air quality (IAQ) and building material biodegradation assessments

FAQ

Does the BMJ-160 support humidity control?
No. This model is a temperature-controlled incubator only; relative humidity is not regulated or monitored.
Can the incubator operate continuously for extended periods (e.g., >30 days)?
Yes. Its integrated refrigeration system, passive defrost design, and thermal overload protection enable unattended operation for weeks under routine laboratory conditions.
Is the RS-485 interface compatible with common lab data acquisition systems?
Yes. It implements standard Modbus RTU protocol at 9600 bps, 8N1 configuration—fully interoperable with National Instruments LabVIEW, Siemens Desigo, and most industrial PLCs.
What validation documentation is supplied?
Factory calibration certificate (traceable to NIM, China), IQ/OQ templates, and electrical safety test report are included. Full PQ support available upon request.
Are replacement shelves and gaskets available as spare parts?
Yes. All consumables and wear components—including silicone door gaskets, stainless steel shelves, and fan assemblies—are stocked and orderable via Boxun’s global distribution network.
