Overview
The Hanuo MJP-80 Mold-Specific Environmental Incubator is a purpose-engineered controlled-environment chamber designed to support the standardized cultivation and maintenance of filamentous fungi, yeasts, and other humidity- and temperature-sensitive microorganisms. Unlike general-purpose incubators, the MJP-80 integrates dual independent regulation of temperature and relative humidity—critical parameters for reproducible mycological growth, spore germination studies, and mold inhibition assays. Its operational principle relies on PID-controlled resistive heating combined with ultrasonic humidification and passive dehumidification via refrigerated condensation, enabling stable setpoint maintenance across the full 0–60 °C and 20–95% RH ranges. The unit complies with core environmental conditioning requirements outlined in ISO 11133:2014 (microbiological culture media preparation), ASTM D3273 (mold resistance testing of building materials), and USP / (microbial enumeration and absence tests), making it suitable for GLP-compliant laboratories engaged in pharmaceutical stability testing, food safety validation, and environmental microbiology.
Key Features
- Stainless steel mirror-finish interior chamber (AISI 304) with integrated UV-C germicidal lamp (254 nm) and ozone-free cold cathode technology for routine sterilization cycles between runs
- Microprocessor-based dual-channel controller with real-time digital display of both temperature and relative humidity; programmable ramp-and-soak profiles with up to 99 segments
- High-precision Pt100 RTD sensors (±0.15 °C accuracy) and capacitive humidity transducers (±2% RH, 30–80% RH range) mounted at three spatially distributed points for uniformity verification
- Adjustable stainless steel shelving system (3 standard shelves, load capacity 15 kg/shelf); shelf height spacing configurable in 25 mm increments without tools
- Optional factory-installed interfaces: RS-232/RS-485 serial port (Modbus RTU protocol), thermal line printer (for audit-trail hardcopy), and independent mechanical overtemperature cutoff (settable 5–65 °C)
Sample Compatibility & Compliance
The MJP-80 accommodates standard microbiological sample formats including Petri dishes (up to 150 mm diameter), multi-well plates (6–96-well), slant tubes, and Erlenmeyer flasks (up to 1 L). Its internal geometry permits unobstructed airflow distribution via rear-mounted axial fans with laminar flow optimization—validated per ISO 14644-1 Class 8 (100,000) cleanroom criteria for particulate control. All electrical components meet IEC 61010-1:2010 safety standards for laboratory equipment. The incubator supports 21 CFR Part 11-compliant data integrity workflows when paired with Hanuo’s optional DataLog Pro software (version 3.2+), providing electronic signatures, user-level access control, and immutable audit trails for temperature/humidity logs.
Software & Data Management
Hanuo DataLog Pro (included with optional interface modules) enables continuous monitoring, remote parameter adjustment, and automated report generation in PDF or CSV format. Data is timestamped with NTP-synchronized UTC and stored locally on encrypted SD card (8 GB supplied) with cyclic overwrite protection. Alarm events—including sensor drift >0.3 °C/2% RH over 5 min, door-open duration >60 s, or humidity deviation >5% RH—are logged with contextual metadata (operator ID, setpoint, chamber zone). Exported datasets comply with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) for regulatory submissions.
Applications
- BOD5 and microbial respiration assays requiring strict O2-limited, high-humidity conditions
- Mycotoxin production studies (e.g., aflatoxin B1 under Aspergillus flavus culture per AOAC 994.10)
- Antifungal susceptibility testing (CLSI M38-A3 guidelines) with gradient plate incubation
- Environmental mold surveillance in HVAC duct swab analysis (EPA/600/R-02/078)
- Seed germination bioassays under controlled hygrothermal stress (ISTA Rules Section 5.4)
- Pharmaceutical excipient stability per ICH Q1A(R2) long-term storage conditions (25 °C/60% RH)
FAQ
Does the MJP-80 meet ISO 14644-1 Class 8 cleanroom specifications for airborne particle counts?
Yes—validated air filtration and laminar flow design ensure ≤3,520,000 particles/m³ ≥0.5 µm during steady-state operation.
Can humidity be maintained independently of temperature across the full 0–60 °C range?
Humidity control is fully decoupled from temperature setpoint; however, maximum achievable RH decreases above 45 °C due to saturation limits (e.g., 95% RH max at 30 °C, ~70% RH max at 60 °C).
Is calibration certificate traceable to NIST or CNAS provided with shipment?
A factory-issued calibration report (temperature/humidity) traceable to CNAS-accredited reference standards is included; NIST-traceable certification available upon request (lead time +5 business days).
What is the mean time between failures (MTBF) for the humidification system?
Based on accelerated life testing, MTBF exceeds 12,000 hours under continuous 80% RH operation at 25 °C.
Are third-party LIMS integrations supported?
Yes—via RS-485 Modbus RTU or OPC UA (with optional gateway module), enabling bidirectional data exchange with Thermo Fisher SampleManager, LabVantage, and STARLIMS platforms.
