BOXUN BMJ-800 Mold Incubator

Overview

The BOXUN BMJ-800 Mold Incubator is a precision-engineered, forced-air, refrigerated incubation system designed specifically for the controlled cultivation and maintenance of filamentous fungi, yeasts, and other moisture-tolerant microorganisms under stable thermal conditions. Unlike general-purpose incubators, the BMJ-800 integrates a proprietary air circulation architecture—featuring a centrifugal blower and an optimized multi-directional airflow channel—to ensure uniform thermal distribution across its 800 L working chamber, critical for reproducible mold growth kinetics and colony morphology assessment. Its operational range spans 0°C to 60°C, enabling both low-temperature preservation (e.g., mycelial stock storage) and elevated-temperature incubation (e.g., Aspergillus or Penicillium propagation at 25–30°C). The unit employs an environmentally compliant R134a refrigerant and a hermetically sealed compressor, delivering consistent cooling performance without ozone-depleting substances—fully aligned with ISO 14001-aligned laboratory sustainability practices.

Key Features

• Microprocessor-based PID temperature control with 0.1°C resolution and ±0.5°C fluctuation tolerance, validated per ASTM E2776-21 for incubator stability testing
• Patented integrated refrigeration module with non-energy-consuming, automatic defrost cycle—eliminates thermal transients during long-term operation (e.g., 7–28 day mold assays)
• Forced convection system featuring a high-efficiency centrifugal fan and asymmetric baffle-guided air ducts, achieving ≤±1.5°C uniformity (measured per ISO 2859-1 at 37°C equivalent load conditions)
• 6-tier adjustable stainless-steel shelving system (mirror-finish 304 SS interior); all shelves support ≥15 kg static load and are autoclavable
• Dual-layer insulated door with tempered glass viewport and silicone gasket seal—maintains integrity under continuous operation and minimizes condensation
• RS-485 serial interface compliant with Modbus RTU protocol; supports integration into centralized lab monitoring networks or third-party SCADA systems
• Mechanical door lock and independent over-temperature cut-off circuit provide dual-layer hardware safety per IEC 61010-1 Class II requirements

Sample Compatibility & Compliance

The BMJ-800 accommodates standard microbiological formats including Petri dishes (up to 150 mm), slant tubes, broth culture flasks (≤2 L), and multi-well plates—without airflow obstruction or cross-contamination risk. Its sealed chamber design enables strict anaerobic-compatible workflows when used with gas-tight accessories (e.g., anaerobic jar adapters via optional 30 mm internal diameter access ports). The incubator meets essential regulatory prerequisites for GLP-compliant environmental and pharmaceutical microbiology labs: temperature mapping validation support, audit-ready parameter logging (with timestamped event records), and power-loss recovery preserving setpoints and active program stages. While not humidity-controlled, its robust thermal stability makes it suitable for applications referenced in USP , ISO 11133:2014 (microbiological culture media preparation), and EPA Method 1681 (fungal enumeration in wastewater).

Software & Data Management

The embedded controller stores up to 10 programmable profiles—each supporting 99 sequential cycles with independent ramp/soak parameters—ideal for simulating diurnal temperature shifts in phytopathogenic fungus studies. All operational data (setpoint, actual temperature, alarm events, runtime) are timestamped and retained for ≥30 days internally. Via the RS-485 port, users may export CSV-formatted logs to validated data acquisition software (e.g., LabVIEW or custom Python scripts) for trend analysis, statistical process control (SPC), or 21 CFR Part 11-compliant electronic record archiving when paired with appropriate audit-trail-enabled middleware. Optional thermal printer output provides hard-copy traceability of temperature curves during method validation.

Applications

• Biodeterioration studies on building materials, textiles, and archival documents under standardized ISO 846 fungal resistance testing protocols
• Pharmaceutical stability testing of excipients and APIs per ICH Q1A(R2) guidelines using mold challenge models
• Environmental monitoring of airborne spore loads in HVAC systems and cleanrooms (ISO 14644-1 Class 5–8 environments)
• Agricultural research on mycotoxin-producing fungi (e.g., Fusarium spp.) under controlled thermal stress regimes
• Educational microbiology labs conducting qualitative and quantitative mold identification (e.g., dichotomous key-based taxonomy exercises)
• Regulatory BOD₅ and microbial respiration assays requiring extended incubation at 20–25°C per APHA Standard Methods 5210B

FAQ

Does the BMJ-800 support humidity control?
No. This model is a temperature-controlled incubator only. For combined temp/humidity applications, consider BOXUN’s BHG series humidified incubators.
Can the BMJ-800 be validated for ISO/IEC 17025 accreditation?
Yes. Its documented temperature uniformity, programmable profiles, and data logging capability support IQ/OQ/PQ protocols when executed with NIST-traceable thermocouples and certified calibration services.
Is the RS-485 interface compatible with LabArchives or ELN platforms?
Yes—via Modbus RTU-to-HTTP gateway bridges, enabling direct ingestion of temperature logs into cloud-based ELNs without proprietary drivers.
What is the maximum ambient operating temperature for continuous use?
Rated for ambient conditions up to 30°C at 60% RH. Performance validation required above 25°C ambient per manufacturer’s installation guide.
Are spare parts and service support available internationally?
BOXUN maintains authorized service partners across EU, North America, and ASEAN regions; compressor and controller modules are stocked globally under part numbers BMJ-800-CP-01 and BMJ-800-CTRL-02.
