MKN MJX-160 Mold Incubator

Overview

The MKN MJX-160 Mold Incubator is a purpose-engineered environmental chamber designed for the controlled cultivation of filamentous fungi, yeasts, and other moisture-sensitive microorganisms requiring precise, stable, and reproducible temperature–humidity profiles. Unlike standard bacterial incubators, this unit integrates dual independent control loops for temperature and relative humidity—critical for mycological studies where hyphal growth, sporulation kinetics, and metabolic activity are highly sensitive to ambient vapor pressure. The system operates on a Peltier-assisted or compressor-based thermoelectric cooling platform (depending on configuration), coupled with a capacitive humidity sensor and steam-generating humidification module. Its architecture conforms to ISO 14644-1 Class 8 cleanroom-compatible surface finish standards, ensuring minimal particulate shedding and ease of decontamination between experimental runs.

Key Features

• Microprocessor-controlled dual-parameter regulation: Real-time feedback loops maintain setpoint stability within ±1 °C (temperature) and ±5 %RH (humidity) across the full 160 L working chamber.
• Integrated germicidal UV-C lamp (254 nm): Automatically activated during idle cycles or manually triggered via front-panel interface; lamp life monitored and logged in system diagnostics.
• Corrosion-resistant 304 stainless-steel interior with seamless welded corners and radiused edges—compliant with ISO 13485 cleaning validation requirements for regulated labs.
• Forced-air convection system with rear-mounted centrifugal blower and directional air baffles ensures uniform thermal–hygric distribution (validated per ASTM E2874-22 Annex A2).
• Double-glazed, low-emissivity hollow glass door with anti-fog coating and silicone-sealed perimeter—enables continuous visual monitoring without compromising chamber integrity.
• Compressor protection circuitry includes programmable delay-on-restart (≥3 min), high-pressure cut-off, and ambient temperature compensation to prevent thermal shock under variable lab conditions.

Sample Compatibility & Compliance

The MJX-160 accommodates standard microbiological formats including Petri dishes (up to 150 mm), multi-well plates (6–96-well), slant tubes, and agar-filled culture bottles. Its internal dimensions (520 × 450 × 680 mm W×D×H) support stacked shelf configurations with adjustable stainless-steel racks (3 included). All materials contacting the chamber environment meet USP Class VI biocompatibility criteria. The unit complies with IEC 61010-1:2010 for laboratory electrical safety and carries CE marking under the EU Machinery Directive 2006/42/EC. Optional IQ/OQ documentation packages are available to support GLP and GMP environments governed by FDA 21 CFR Part 11 and ISO/IEC 17025 accreditation protocols.

Software & Data Management

Equipped with an embedded 4.3-inch TFT-LCD touchscreen interface supporting multilingual operation (English, Spanish, German, Chinese), the incubator records timestamped temperature–humidity logs at user-selectable intervals (1–60 min). Data export is supported via USB 2.0 port (FAT32-formatted drive) in CSV format compatible with LIMS integration. Optional RS-485 Modbus RTU communication enables centralized monitoring through SCADA or building management systems. Audit trail functionality captures operator ID, parameter changes, alarm events, and UV activation history—fully traceable for regulatory review.

Applications

• Standardized fungal growth assays per ISO 13843:2021 (microbiological risk assessment in food and feed)
• Mycotoxin production studies under defined water activity (a_w) conditions
• Antifungal susceptibility testing (AFST) using CLSI M38-A3 methodology
• Environmental simulation for biodegradation testing of polymers and coatings (ASTM D5511)
• Long-term strain preservation of dermatophytes and Aspergillus spp. at suboptimal growth temperatures
• Educational microbiology labs requiring ISO/IEC 17025-aligned equipment traceability

FAQ

Does the MJX-160 support remote monitoring via Ethernet or Wi-Fi?
No—standard configuration uses local touchscreen and USB data export only. Ethernet/Wi-Fi modules are available as factory-installed options (part number: MJX-160-EM1).

What is the maximum allowable load volume without compromising humidity uniformity?
For optimal RH homogeneity (±5 %RH across chamber), loading should not exceed 60 % of total volume (≤96 L net space). Dense stacking requires additional equilibration time (recommended: ≥2 h after door closure).

Is the UV lamp intensity calibrated and certified?
Yes—each unit ships with a NIST-traceable UV irradiance certificate (254 nm, measured at 1 m distance). Lamp output decays linearly; replacement interval is specified at 8,000 hours or per annual photometric verification.

Can the incubator operate continuously for extended periods (e.g., 30+ days)?
Yes—designed for uninterrupted operation under Class II laboratory conditions (ISO 14644-1). Compressor duty cycle and humidity pump maintenance intervals are specified in the technical manual (Section 5.2).

Are third-party validation services available for IQ/OQ/PQ protocols?
MKN partners with ISO/IEC 17025-accredited service providers in North America, EU, and APAC regions. Contact technical support for region-specific vendor referrals and protocol templates.
