JingHong MJPS-250Y Programmable Mold Incubator with Humidity Control

Overview

The JingHong MJPS-250Y is a programmable mold incubator engineered for precise, reproducible microbial cultivation under controlled temperature and relative humidity conditions. Designed specifically for mycological research and quality control applications, it operates on the principle of forced-air convection to ensure uniform thermal and hygric distribution throughout the 250 L working chamber. Its dual-control architecture integrates microprocessor-based PID regulation for temperature stability (±0.5 °C) and robust humidity management (50–90 %RH, ±5 %RH), meeting critical requirements for fungal growth studies, BOD testing, environmental monitoring, and pharmaceutical stability assessments. The unit complies with fundamental design principles aligned with ISO 14644-1 cleanroom air handling concepts and supports GLP-compliant workflows through traceable parameter logging and user-accessible calibration interfaces.

Key Features

• Mirror-finish stainless steel interior chamber with seamless semi-circular corners—designed for easy cleaning, corrosion resistance, and compliance with microbiological containment standards.
• 30-segment programmable touchscreen controller with intuitive graphical interface; supports multi-curve process scheduling, real-time parameter visualization, and context-sensitive on-screen help menus for rapid operator onboarding.
• Dual-door insulation system: outer door with high-efficiency thermal seal and inner tempered glass door—enables visual inspection without thermal disturbance or condensation interference.
• Modular refrigeration module incorporating eco-friendly R134a refrigerant, delayed-start circuitry, and dual-pressure safety monitoring (high/low pressure cut-off) for sustained operational reliability.
• Integrated UV-C germicidal lamp (254 nm) for routine chamber decontamination between cycles—reducing cross-contamination risk in serial inoculation protocols.
• Adjustable stainless steel shelving with tool-free height reconfiguration—optimized for flexible sample loading and airflow optimization across diverse vessel types (Petri dishes, slants, flasks, multi-well plates).

Sample Compatibility & Compliance

The MJPS-250Y accommodates standard microbiological sample formats including agar plates, liquid culture tubes, Erlenmeyer flasks (up to 2 L), and environmental sampling filters. Its chamber geometry and airflow dynamics are validated for uniform environmental delivery per ASTM D3273 (Standard Test Method for Resistance to Fungal Growth on Plastic and Other Non-porous Surfaces). The unit meets essential electrical safety requirements per IEC 61010-1 and incorporates grounding continuity, overtemperature protection, and insulated power supply isolation. Optional RS-485 Modbus RTU communication enables integration into centralized laboratory monitoring systems compliant with FDA 21 CFR Part 11 when paired with validated data acquisition software.

Software & Data Management

The embedded controller supports timestamped event logging—including setpoint changes, alarm triggers (e.g., door open, temp/humidity deviation), and cycle completion—with local storage capacity for ≥10,000 records. Optional embedded thermal printer (model PRN-250T) provides hard-copy audit trails suitable for QA documentation. When connected via RS-485 to third-party LIMS or SCADA platforms, the incubator transmits real-time sensor values (chamber temp, RH, compressor status) at configurable intervals (1–60 s). All configuration parameters—including PID coefficients, alarm thresholds, and program sequences—are password-protected and support role-based access levels (Operator, Technician, Administrator).

Applications

• Fungal isolation and identification in clinical, food, and environmental laboratories per USP Sterility Tests and ISO 11133:2014 Microbiology of food and animal feeding stuffs—Guidelines for performance testing of culture media.
• Biochemical Oxygen Demand (BOD₅) analysis in wastewater treatment facilities, where stable 20 °C ±0.5 °C and minimal humidity drift are mandated by APHA Standard Methods 5210B.
• Pharmaceutical stability testing of excipients and finished dosage forms under ICH Q1A(R2) long-term and accelerated storage conditions (e.g., 25 °C/60 %RH, 30 °C/65 %RH).
• Agricultural seed germination assays and plant pathogen challenge studies requiring defined hygrothermal profiles over extended durations (7–28 days).
• Microbial shelf-life modeling for cosmetics and personal care products under ISO 11930:2023 guidelines.

FAQ

What is the maximum allowable ambient temperature for continuous operation?
The MJPS-250Y is rated for uninterrupted use in ambient environments up to 32 °C, provided adequate ventilation clearance (≥100 mm on all sides) and relative humidity below 80 %RH.
Does the unit support remote monitoring via Ethernet or Wi-Fi?
No native Ethernet or Wi-Fi interface is included; however, RS-485 connectivity allows integration with industrial gateways supporting TCP/IP translation for networked supervision.
Can humidity be maintained independently of temperature settings?
Yes—the controller decouples humidity and temperature control loops, enabling independent setpoint definition and dynamic adjustment during multi-step programs.
Is calibration certificate included with shipment?
A factory-issued calibration report (traceable to NIM, China) is supplied, covering temperature and humidity sensors at three points (20 °C/60 %RH, 30 °C/75 %RH, 40 °C/85 %RH); ISO/IEC 17025-accredited field calibration services are available upon request.
What safety certifications does the MJPS-250Y hold?
It carries CCC (China Compulsory Certification) and conforms to GB 4793.1–2019 (equivalent to IEC 61010-1:2010) for laboratory equipment safety; CE marking is not applicable as it is manufactured for domestic and select export markets without EU Notified Body assessment.
