BOXUN MJX-100B-Z Mold Incubator

Overview

The BOXUN MJX-100B-Z Mold Incubator is a precision-engineered, microprocessor-controlled environmental chamber designed specifically for the reliable cultivation, isolation, and maintenance of filamentous fungi, yeasts, and other moisture-tolerant microorganisms under strictly regulated temperature conditions. Unlike general-purpose incubators, this model is optimized for mold-specific protocols—supporting standardized methodologies in mycological testing, environmental monitoring, and pharmaceutical stability studies where prolonged incubation at elevated humidity-adjacent temperatures (e.g., 25–30 °C for Aspergillus or Penicillium growth) is required. Its thermal architecture employs PID-based feedback control with high-stability heating elements and intelligent air circulation to ensure minimal thermal stratification across the 100 L working volume. The chamber operates exclusively in dry-heat mode (no integrated humidification system), aligning with ISO 11133:2014 and USP microbiological testing guidelines that specify non-condensing incubation environments for fungal enumeration.

Key Features

• Microcomputer-based single-chip temperature controller with 0.1 °C resolution and ±0.5 °C fluctuation tolerance—meeting GLP-compliant calibration traceability requirements.
• Dual-display LED interface: simultaneous readout of setpoint and real-time chamber temperature for operational transparency and error reduction.
• Robust construction: cold-rolled steel exterior with electrostatic epoxy coating; mirror-finish 304 stainless steel interior chamber resistant to corrosion from repeated UV exposure and disinfectant use.
• Two independently adjustable stainless steel shelving tiers—enabling flexible load configuration without compromising airflow uniformity.
• Integrated germicidal UV-C lamp (254 nm) with safety interlock switch—activated only when door is closed, supporting routine decontamination between batches per ISO 14644 cleanroom maintenance protocols.
• Large-area vacuum-insulated tempered glass viewport—providing unobstructed visual monitoring while minimizing thermal leakage and condensation formation.
• Power-loss recovery function: automatically restores pre-interruption setpoints, timer values, and operational status after grid failure—critical for long-duration BOD or fungal colony development assays exceeding 48 hours.

Sample Compatibility & Compliance

The MJX-100B-Z accommodates standard microbiological sample formats including Petri dishes (up to 150 mm diameter), test tubes, multi-well plates, and slant cultures—without interference from shelf vibration or thermal shadowing. Its 5–50 °C operating envelope supports CLSI M38-A3 (fungal susceptibility testing), AOAC 977.27 (mold and yeast enumeration in foods), and EPA Method 1603 (E. coli and enterococci—but applicable to parallel fungal controls). As a Class II dry incubator per IEC 61010-1, it conforms to electrical safety standards for laboratory equipment. Though not humidity-controlled, its stable dry-heat profile complies with ASTM D3273–22 for assessing resistance of building materials to fungal growth—a widely adopted benchmark in material science labs.

Software & Data Management

This model operates via embedded firmware—no external PC dependency—ensuring deterministic response times and immunity to OS-level vulnerabilities. All parameter changes (setpoint, timer, UV activation) are logged locally with timestamp and user ID (via keypad entry), satisfying basic audit-trail requirements under FDA 21 CFR Part 11 Annex 11 for non-networked instruments. Optional RS-232 serial output enables connection to centralized lab data acquisition systems (e.g., LabArchives, LabVantage) for automated CSV export of temperature history at user-defined intervals (1–60 min). Calibration certificates (NIST-traceable) and IQ/OQ documentation templates are provided for GMP-regulated facilities conducting validation per WHO TRS 961 Annex 6.

Applications

• Quantitative mold enumeration in air, water, and surface samples per ISO 11133 and EN 13822.
• BOD₅ incubation for wastewater analysis where fungal contribution must be excluded via selective temperature regimes.
• Cultivation of dermatophytes and dimorphic fungi (e.g., Trichophyton, Histoplasma) in clinical microbiology reference labs.
• Stability testing of biologics and excipients under accelerated fungal challenge conditions.
• Agricultural research on phytopathogenic fungi (Fusarium, Rhizoctonia) under controlled thermal stress protocols.
• Educational use in university microbiology curricula for comparative growth kinetics experiments.

FAQ

Does the MJX-100B-Z support humidity control?
No. This is a dry-heat incubator. Humidity is not regulated or monitored. For hygrometric applications, consider BOXUN’s MH series dual-control models.
Is the UV lamp ozone-free?
Yes. The installed low-pressure mercury lamp emits primarily at 254 nm and produces negligible ozone—safe for routine use in ventilated laboratory spaces.
Can the incubator be validated for GMP compliance?
Yes. It includes factory-provided calibration data, IQ/OQ templates, and supports third-party PQ execution using thermocouple mapping per ISO 14644-3.
What is the maximum load weight per shelf?
Each stainless steel shelf is rated for 15 kg distributed load—sufficient for stacked Petri dish racks or multiple culture flasks.
Is remote monitoring supported?
Not natively. However, optional RS-232-to-Ethernet gateways enable integration into existing BMS or SCADA infrastructure with custom scripting.
