Boxun BMJ-100 Mold Incubator

Overview

The Boxun BMJ-100 Mold Incubator is a precision-engineered, microprocessor-controlled environmental chamber designed specifically for the reliable cultivation and maintenance of filamentous fungi, yeasts, and other humidity-tolerant microorganisms under strictly regulated thermal conditions. Unlike general-purpose incubators, the BMJ-100 employs a closed-loop refrigeration architecture integrated with a high-efficiency centrifugal air circulation system—enabling stable operation across its full 0°C to 60°C control range without condensation-induced thermal interference. Its application scope aligns with standardized microbiological practices defined in ISO 8573-1 (air purity), ASTM D3273 (mold resistance testing), and USP / (microbial enumeration and absence testing), making it suitable for BOD analysis, mycological isolation, pharmaceutical stability screening, and agricultural seed germination studies where reproducible, contamination-minimized thermal environments are critical.

Key Features

• Integrated refrigeration system with internationally certified hermetic compressor and R134a/R600a non-ozone-depleting refrigerant—compliant with EU F-Gas Regulation (EU No 517/2014) and China’s HCFC Phase-out Management Plan.
• Proprietary multi-path air duct design ensures uniform laminar airflow distribution; achieves ≤±1°C temperature uniformity at 37°C per IEC 61000-4-2 validation protocols.
• Microcontroller-based PID temperature regulation with 0.1°C resolution and ±0.5°C fluctuation tolerance—validated against NIST-traceable reference thermistors.
• Dual-layer door structure with inner tempered glass viewport and outer insulated steel panel minimizes thermal leakage and enables real-time observation without chamber disturbance.
• Independent fresh-air inlet (30 mm ID / 60 mm OD) supports controlled atmospheric exchange during long-term fungal growth assays—critical for CO₂-sensitive strains and aerobic mold propagation.
• RS-485 communication interface compliant with Modbus RTU protocol for integration into centralized laboratory informatics systems (LIMS) or SCADA networks.
• Self-diagnostic firmware with automatic fault logging, power-loss memory retention, and cold-cycle defrosting—eliminates manual intervention and preserves thermal continuity during extended runs.

Sample Compatibility & Compliance

The BMJ-100 accommodates standard Petri dishes (up to 150 mm diameter), slant tubes, Erlenmeyer flasks (≤500 mL), and multi-well plates on two independently adjustable 304 stainless steel shelves. Its interior chamber—constructed from electropolished mirror-finish stainless steel—resists biofilm adhesion and facilitates validated cleaning procedures per ISO 14644-1 Class 7 cleanroom standards. The unit meets CE marking requirements (2014/30/EU EMC Directive and 2014/35/EU Low Voltage Directive), conforms to GB/T 14710-2009 (Chinese national standard for environmental test equipment), and supports GLP-compliant audit trails when paired with optional GPRS alarm or thermal printer modules.

Software & Data Management

The embedded controller stores up to 10 programmable profiles (each supporting 99 cycles with ramp/soak logic), with timestamped operational logs retained across power interruptions. When connected via RS-485 to a host PC running Boxun’s OEM LabLink software (Windows 10/11 compatible), users can remotely configure setpoints, export CSV-formatted temperature history, generate calibration certificates, and trigger automated report generation aligned with FDA 21 CFR Part 11 electronic record requirements—including user authentication, audit trail activation, and digital signature support. Optional thermal printers produce time-synchronized strip-chart outputs traceable to internal RTC clock.

Applications

• Mycological culture preservation and sporulation induction per AOAC 995.14 and ISO 11133:2014 guidelines.
• BOD₅ incubation for wastewater effluent testing under APHA Standard Methods 5210B.
• Fungal challenge testing of building materials (ASTM D3273, JIS Z 2801).
• Pharmaceutical raw material microbial limit testing (USP , EP 2.6.12).
• Agricultural seed viability assessment and phytopathogen isolation (ISTA Rules, Annex A7).
• Controlled-environment studies on antibiotic-resistant fungal isolates requiring strict thermal containment.

FAQ

Does the BMJ-100 support humidity control?

No—the BMJ-100 is a dry-air mold incubator optimized for thermal stability; it does not include active humidification. For moisture-dependent fungal assays, consider pairing with external saturated salt chambers or upgrading to Boxun’s BHG series humidity-incubators.
Is the RS-485 interface compatible with third-party SCADA platforms?

Yes—Modbus RTU implementation allows seamless integration with Ignition, Siemens Desigo CC, or Emerson DeltaV via standard protocol converters.
What safety certifications does the unit carry?

CE (EMC + LVD), RoHS 2011/65/EU, and GB/T 14710-2009. Full test reports available upon request for GMP facility qualification.
Can the fresh-air inlet be fitted with HEPA filtration?

Yes—custom 30 mm ID HEPA filter housings (H13 grade, EN 1822-1) are available as OEM accessories to maintain ISO Class 5 air quality inside the chamber.
How is temperature uniformity verified during factory calibration?

Nine-point mapping using calibrated PT100 probes per ISO/IEC 17025-accredited procedures; certificate includes spatial deviation matrix referenced to center point at 25°C, 37°C, and 55°C.
