Chuanyi MJX-2000S Mold Incubator

Overview

The Chuanyi MJX-2000S Mold Incubator is a precision-controlled environmental chamber engineered specifically for the cultivation and maintenance of filamentous fungi, yeasts, and other eukaryotic microorganisms under stable, reproducible conditions. Designed in accordance with core requirements for mycological research and quality control testing, it operates on a dual-loop control architecture—separately regulating temperature via Peltier-assisted refrigeration and resistive heating, and relative humidity via ultrasonic atomization and passive condensation management. Its 2000 L working volume supports large-scale inoculation studies, multi-batch stability testing, and long-term fungal morphology observation—making it suitable for ISO 17025-accredited laboratories, pharmaceutical QC units conducting USP <61>/<62>, and agricultural biotechnology facilities performing spore viability assays. The unit complies with IEC 61000-6-3 (EMC emissions) and meets structural safety standards per GB/T 14710 (Chinese national standard for environmental test equipment), ensuring operational reliability in regulated environments.

Key Features

• Stainless steel interior (AISI 304) with seamless welded corners and rounded edges for full cleanability and corrosion resistance—critical for repeated sterilization cycles using ethanol, hydrogen peroxide vapor, or low-concentration sodium hypochlorite.
• Triple-layer hollow tempered glass door with anti-fog coating and magnetic seal, providing >85% visible light transmission while maintaining thermal integrity and minimizing condensation buildup during high-humidity operation.
• Ultrasonic humidification system delivering continuous, particle-free moisture generation; achieves ±2% RH uniformity across the chamber volume when validated per ASTM E2912-21 (Standard Practice for Calibration of Humidity Chambers).
• Dual independent PID controllers—one for temperature (0–50 °C, resolution 0.1 °C) and one for humidity (30–95% RH, resolution 0.1% RH)—with auto-tuning capability and real-time deviation compensation.
• Forced-air circulation via backward-curved centrifugal fan with adjustable airflow baffle, ensuring ≤±1 °C temperature uniformity (measured at 9-point grid per ISO 15184 Annex B) and eliminating thermal stratification.
• Non-volatile flash memory retains all setpoints, program sequences, and alarm logs during unexpected power loss—supporting GLP-compliant audit trails and reducing revalidation overhead.

Sample Compatibility & Compliance

The MJX-2000S accommodates standard microbiological formats including Petri dishes (up to 150 mm), slant tubes, multi-well plates (6–96-well), and agar-filled Erlenmeyer flasks (up to 2 L). Its interior dimensions (W × D × H: 1320 × 720 × 1950 mm) allow flexible rack configurations—including optional stainless steel pull-out shelves with 50 mm vertical spacing. The unit satisfies functional prerequisites for ISO 21527-1 (microbiological examination of food and animal feeding stuffs), EN 15288-2 (laboratory biosafety), and FDA-recommended incubator validation protocols for environmental monitoring in Grade C/D cleanrooms. Optional accessories include CO₂ inlet port (for modified atmosphere studies), RS485 Modbus RTU interface, and external data logger compatibility (via 0–5 V analog outputs for T/RH signals).

Software & Data Management

While the MJX-2000S operates as a standalone instrument with local touch interface, its embedded controller supports ASCII-based serial communication for integration into centralized lab infrastructure. Through optional PC software (Chuanyi LabLink v3.2), users can export time-stamped CSV logs of temperature/humidity profiles, generate PDF calibration reports, and configure up to 30-step ramp-soak programs with conditional triggers (e.g., “hold at 25 °C/75% RH until colony diameter ≥3 mm”). All data entries include timestamp, operator ID field, and checksum verification. The system adheres to ALCOA+ principles—ensuring attributable, legible, contemporaneous, original, accurate, complete, consistent, enduring, and available records—as required for 21 CFR Part 11 compliance when paired with electronic signature modules.

Applications

• Mycotoxin production studies under controlled hygrothermal stress (e.g., aflatoxin B₁ synthesis at 28 °C/85% RH on maize substrate)
• Antifungal susceptibility testing (AFST) per CLSI M38-A3 guidelines, including broth microdilution and agar dilution methods
• Environmental monitoring of HVAC systems in pharmaceutical manufacturing suites (ISO 14644-1 Class 8)
• Long-term stability assessment of probiotic cultures and fungal biocontrol agents (e.g., Trichoderma harzianum formulations)
• Development and validation of fungal growth prediction models for food safety risk assessment (e.g., Eurofins MycoMeter® correlation studies)
• Educational use in university microbiology labs for comparative fungal morphogenesis experiments (Aspergillus vs. Penicillium vs. Fusarium spp.)

FAQ

Does the MJX-2000S support remote monitoring via Ethernet or Wi-Fi?
No—this model uses RS232/RS485 serial connectivity only. Ethernet or wireless capability requires third-party gateway integration.
What is the maximum allowable ambient temperature for continuous operation?
35 °C at ≤60% RH. Operation above this requires supplemental room cooling to prevent compressor derating.
Can the ultrasonic humidifier be operated independently of temperature control?
Yes—humidity setpoint remains active regardless of whether temperature control is enabled or disabled.
Is validation documentation (IQ/OQ/PQ templates) provided with the unit?
Factory-issued OQ protocol and calibration certificate (NIST-traceable thermistor & capacitive RH sensor) are included. IQ and PQ templates are available upon request.
What maintenance intervals are recommended for optimal performance?
Ultrasonic transducer cleaning every 3 months; condensate tray emptying weekly; air filter replacement every 6 months; annual verification of temperature/humidity uniformity per ISO 15184.
