ZOLLO MJX-2000S 2000L Temperature and Humidity Controlled Mold Incubation Chamber

Overview

The ZOLLO MJX-2000S is a large-capacity, precision-engineered temperature and humidity controlled mold incubation chamber designed for standardized fungal growth testing, long-term stability studies, and environmental stress evaluation of materials and biological specimens. Operating on the principle of closed-loop PID regulation for both thermal and hygroscopic control, the MJX-2000S maintains stable, reproducible conditions across its 2000-liter working volume—critical for ASTM G21, ISO 846, IEC 60068-2-10, and other internationally recognized mold resistance test protocols. Its robust architecture integrates an imported high-efficiency compressor, ultrasonic humidification system, and triple-layer insulated glass doors to minimize thermal bridging and ensure uniform environmental distribution—validated per IEC 60068-3-5 for chamber homogeneity. The unit complies with GLP-compliant operation requirements, supporting audit-ready documentation when paired with optional data logging software.

Key Features

• Microprocessor-based control system with intuitive touch-panel interface and dual digital displays for simultaneous real-time monitoring of temperature (°C) and relative humidity (%RH).
• Ultrasonic humidification module ensures rapid, particle-free moisture delivery with ±2 %RH uniformity—eliminating condensation risks and avoiding mineral residue accumulation common in steam-based systems.
• Stainless steel (AISI 304) interior chamber resists corrosion, facilitates decontamination, and complies with ISO 14644-1 Class 8 cleanroom-compatible surface finish standards.
• Quadruple-door configuration with triple-layer hollow insulated glass provides superior thermal insulation (U-value ≤ 0.8 W/m²·K), reducing energy consumption and enhancing operational stability during extended test cycles.
• Dedicated over-temperature and sensor fault protection circuits interrupt power to heating elements upon deviation beyond ±3 °C or open-circuit detection—ensuring sample integrity and operator safety per IEC 61000-4-5 surge immunity guidelines.
• Modular design supports field-upgradable firmware and optional accessories including external CO₂ sensors, UV-C sterilization modules, and Ethernet-enabled remote supervision.

Sample Compatibility & Compliance

The MJX-2000S accommodates diverse sample formats—including petri dishes, ISO-standard test panels (e.g., ASTM D3273 substrates), electronic components on trays, polymer sheets, and packaged consumer goods—within its uniformly conditioned workspace. Its chamber geometry and airflow management (non-turbulent, top-down laminar recirculation) prevent localized desiccation or condensation, meeting the spatial uniformity criteria specified in ISO 16750-4 for environmental simulation equipment. The system supports full traceability under GLP and GMP frameworks: when equipped with optional time-stamped data logging, it generates tamper-evident CSV reports compliant with FDA 21 CFR Part 11 requirements for electronic records and signatures. Validation documentation (IQ/OQ/PQ templates) is provided to facilitate user qualification against ISO/IEC 17025 laboratory accreditation criteria.

Software & Data Management

The MJX-2000S supports two-tier data handling: onboard storage retains up to 30 days of 1-minute interval temperature/humidity logs (with timestamp, setpoint, and deviation values), while the optional PC connectivity kit enables continuous acquisition via ZOLLO’s proprietary LabChamber Suite v3.2. This Windows-based application offers real-time graphing, alarm event tagging, automated report generation (PDF/Excel), and configurable export to LIMS platforms via OPC UA or Modbus TCP. All logged parameters are encrypted at rest and include digital signature verification to satisfy ALCOA+ data integrity principles. Audit trails record user login/logout events, parameter changes, and calibration interventions—fully aligned with Annex 11 and EU GMP Chapter 4 expectations.

Applications

• Fungal resistance testing of construction materials, textiles, coatings, and packaging per ASTM G21, ISO 846, and JIS Z 2911.
• Accelerated aging of pharmaceutical packaging and medical device housings under high-humidity tropical conditions (ICH Q1A, Q5C).
• Long-term stability assessment of hygroscopic electronics, adhesives, and composite laminates per IPC-9701 and MIL-STD-810H Method 507.6.
• Controlled germination and mycelial propagation studies in mycology and plant pathology research laboratories.
• Environmental stress screening of automotive interior components per VW 80101 and GMW 15635.
• Validation of HVAC filtration efficacy using bioaerosol challenge protocols (e.g., ASHRAE Standard 145.1).

FAQ

What standards does the MJX-2000S comply with for mold testing?
It is engineered to meet the environmental control requirements of ASTM G21, ISO 846, IEC 60068-2-10, and JIS Z 2911—including specified temperature/humidity tolerances, uniformity, and recovery time performance.
Can the chamber be validated for GMP use?
Yes—ZOLLO supplies IQ/OQ/PQ documentation templates, and the optional data logging system supports 21 CFR Part 11 compliance when configured with user access controls and electronic signatures.
Is stainless steel grade 304 sufficient for aggressive fungal culture environments?
AISI 304 stainless steel provides optimal corrosion resistance against organic acids secreted by Aspergillus niger and Penicillium chrysogenum under sustained 95 %RH exposure, as verified per ASTM A262 Practice E.
How is humidity uniformity verified across the 2000L volume?
Uniformity is confirmed using nine-point NIST-traceable probe mapping per ISO 16750-4 Annex B, with maximum deviation limited to ±2 %RH at any location within the working volume.
Does the ultrasonic humidifier require demineralized water?
Yes—use of deionized or distilled water (conductivity < 5 µS/cm) is mandatory to prevent scaling and maintain consistent aerosol output and sensor accuracy over time.
