Yoyilab MJ-70-I Mold Incubator

Overview

The Yoyilab MJ-70-I Mold Incubator is a purpose-engineered environmental chamber designed for controlled fungal cultivation, microbial preservation, and BOD testing in life science and quality control laboratories. It operates on the principle of forced-air convection to ensure rapid thermal equilibration and stable temperature distribution across the working chamber—critical for reproducible mycological growth studies, stability testing of pharmaceuticals, and environmental monitoring per ISO 8513 and ASTM D3273 standards. The unit maintains precise thermal conditions within a broad operational range (0–65 °C), supporting both mesophilic and thermotolerant mold species such as Aspergillus niger, Penicillium chrysogenum, and Cladosporium herbarum. Its robust architecture—including cold-rolled steel exterior with electrostatic epoxy coating and mirror-finish stainless-steel interior—ensures long-term corrosion resistance and compliance with GLP laboratory infrastructure requirements.

Key Features

• Forced-air convection system with adjustable fan speed for optimized airflow dynamics and minimized thermal stratification
• Dual-door structure with insulated glass viewport and silicone gasket seal to preserve internal environment during observation
• Microprocessor-based PID temperature controller with 0.1 °C resolution, real-time display, and programmable timer (1–9999 minutes)
• Power-loss recovery function with non-volatile memory retention for setpoints and runtime parameters
• Over-temperature deviation protection circuit with audible/visual alarm activation above user-defined thresholds
• Integrated UV-C germicidal lamp (254 nm) mounted in ceiling plenum for continuous air sterilization between cycles
• Four-corner rounded interior design and removable, height-adjustable stainless-steel shelves for ease of cleaning and spatial flexibility
• Omni-directional casters with locking mechanism and independent leveling feet for stable positioning on uneven floors

Sample Compatibility & Compliance

The MJ-70-I accommodates standard Petri dishes (90 mm and 150 mm), slant tubes, multi-well plates, and liquid culture flasks up to 500 mL volume. Its chamber geometry supports simultaneous incubation of heterogeneous sample types without cross-contamination risk. The unit meets essential safety and performance benchmarks including IEC 61010-1 (electrical safety), EN 60529 (IP20 ingress protection), and conforms to Good Laboratory Practice (GLP) documentation requirements for audit-ready operation logs when paired with optional RS485 interface. While not humidity-controlled (model variant MJ-70-II provides RH regulation), the MJ-70-I’s dry-heat capability aligns with USP Chapter <1111> guidelines for non-sterile product microbial limit testing and ISO 11133:2014 Annex C for fungal culture media validation.

Software & Data Management

Standard operation requires no external software—the 5.7-inch LCD interface enables intuitive menu-driven configuration of temperature setpoint, hold duration, and alarm thresholds. Optional RS485 communication module (sold separately) enables integration into centralized lab management systems via Modbus RTU protocol, supporting automated data logging, remote status monitoring, and electronic record generation compliant with FDA 21 CFR Part 11 Annex 11 requirements. When configured with the optional multi-segment programmable controller, users may define up to 99 cycles with 30 steps per cycle—enabling complex ramp-hold-cool protocols required for accelerated aging studies or temperature-stress screening of biologics.

Applications

• Fungal strain maintenance and sporulation induction under defined thermal regimes
• Biochemical Oxygen Demand (BOD₅) incubation per Standard Methods 5210B and ISO 5815-1
• Antifungal efficacy testing (e.g., ISO 16000-10, JIS Z 2801)
• Environmental microbiology sampling analysis (water, air, surface swabs)
• Stability assessment of probiotic formulations and fermented food products
• Mycotoxin production studies requiring extended incubation at elevated temperatures
• Evaluation of antimicrobial resistance development in filamentous fungi

FAQ

Is the MJ-70-I suitable for cell culture applications?
No—it lacks CO₂ control, humidity regulation, and HEPA filtration; it is specifically validated for mold and bacterial incubation only.
Can this incubator be used for sterility testing?
It supports pre-incubation of test samples but does not replace ISO 14644-compliant cleanroom environments or aseptic processing workflows.
What is the maximum ambient temperature for reliable operation?
Rated for continuous use at ambient temperatures ≤30 °C and relative humidity ≤80% RH (non-condensing).
Does the unit include calibration certification?
Factory calibration is performed at 25 °C and 37 °C; NIST-traceable calibration certificates are available upon request (additional fee applies).
Are spare parts and service support available internationally?
Yes—Yoyilab provides global technical documentation, OEM replacement components (fans, sensors, UV lamps), and authorized service partner referrals through regional distributors.
