JingHong MJPS-150Y Programmable Mold Incubator with Humidity Control

Overview

The JingHong MJPS-150Y is a purpose-engineered programmable mold incubator designed for controlled fungal cultivation, microbiological preservation, and environmental simulation in regulated life science laboratories. It operates on the principle of precision thermohygrometric regulation—integrating microprocessor-based PID temperature control with independent humidity modulation via evaporative saturation and condensation management. Unlike general-purpose incubators, the MJPS series is specifically optimized for mycological applications where stable, reproducible moisture gradients are critical to spore germination, hyphal growth kinetics, and colony morphology assessment. Its forced-air convection system ensures uniform thermal distribution across the entire 150 L chamber volume, minimizing stratification and supporting compliance with ISO 21527-1 (microbiological methods for yeasts and molds) and USP microbial enumeration requirements.

Key Features

• Mirror-finish stainless steel interior with seamless, radius-rounded corners for validated cleaning and reduced microbial retention.
• Dual-door architecture: outer insulated door and inner tempered glass door—enabling real-time visual monitoring without compromising chamber stability or introducing thermal shock.
• Integrated UV-C germicidal lamp (254 nm) for periodic decontamination between cycles, supporting GLP-aligned aseptic workflow protocols.
• Programmable touchscreen controller supporting up to 30 segmented ramp-soak temperature/humidity profiles, with event logging and parameter recall functionality.
• Modular refrigeration unit featuring R134a-free eco-refrigerant, high/low pressure protection, and compressor delay startup to extend service life and ensure long-term calibration integrity.
• Optional RS-485 interface compliant with Modbus RTU protocol for integration into centralized lab monitoring systems (e.g., LabVantage, Thermo Fisher SampleManager).
• Configurable alarm outputs—including overtemperature, low humidity, door ajar, and compressor fault—with optional SMS notification via GSM module (IEC 62304 Class B software architecture).

Sample Compatibility & Compliance

The MJPS-150Y accommodates standard Petri dishes (90 mm and 150 mm), multi-well plates, slant tubes, and liquid culture flasks. Its internal dimensions (500 × 450 × 650 mm) permit vertical stacking of up to four adjustable stainless steel shelves (load capacity: 15 kg per shelf). The unit meets IEC 61010-1:2010 safety standards for laboratory equipment and conforms to EN 60335-2-86 for incubator-specific electrical safety. Humidity control performance aligns with ASTM E2912–22 for environmental chamber verification, while temperature stability supports adherence to CLSI M22-A3 guidelines for fungal susceptibility testing environments.

Software & Data Management

The embedded controller provides full audit trail capability—including user login timestamps, parameter change logs, alarm history, and cycle completion records—all stored in non-volatile memory with time/date stamping. Data export is supported via USB flash drive (CSV format) or real-time streaming via RS-485 to external SCADA or LIMS platforms. Optional firmware upgrade enables 21 CFR Part 11-compliant electronic signatures, role-based access control, and automated report generation for QA/QC documentation. All configuration changes require dual-user authentication, satisfying GMP Annex 11 data integrity expectations.

Applications

• Regulatory microbiology: Mold and yeast enumeration per ISO 7954 and FDA BAM Chapter 18.
• BOD₅ incubation under standardized 20 °C / 5-day conditions (APHA Standard Methods 5210B).
• Fungal strain preservation and subculturing in pharmaceutical QC labs (ICH Q5D).
• Environmental monitoring of cleanrooms and isolators per ISO 14644-1 Class 5–8.
• Agricultural research: seed-borne pathogen isolation, phytopathogenic fungus development studies.
• Toxicology and ecotoxicology: aquatic toxicity bioassays requiring controlled humidity during algal or fungal exposure phases.

FAQ

What is the maximum allowable load weight per shelf?
Each adjustable stainless steel shelf supports up to 15 kg under static loading conditions.
Does the unit support validation protocols such as IQ/OQ/PQ?
Yes—the MJPS-150Y includes factory-installed sensor ports for third-party validation probes and ships with a complete DQ/IQ/OQ documentation package upon request.
Can humidity be maintained independently of temperature settings?
Yes—humidity control operates via dedicated evaporation chamber and feedback loop, decoupled from thermal regulation to enable isothermal humidification or dehumidification cycles.
Is the UV lamp automatically interlocked with the door switch?
Yes—UV emission is disabled whenever the inner or outer door is opened, meeting IEC 62471 photobiological safety requirements.
What communication protocols are supported beyond RS-485?
Standard configuration supports Modbus RTU only; Ethernet/IP or OPC UA interfaces are available as custom-engineered options under OEM agreement.
