Overview
The Yoyilab MJ-150-I Mold Incubator is a precision-engineered environmental chamber designed for controlled cultivation of fungi, yeasts, molds, and other aerobic microorganisms under stable thermal conditions. It operates on the principle of forced-air convection combined with microcomputer-based PID (Proportional-Integral-Derivative) temperature regulation to maintain consistent thermal profiles across the working chamber—critical for reproducible microbiological assays, BOD testing, stability studies, and antimicrobial efficacy evaluation per ISO 8583, ASTM D3273, and USP . The unit meets core requirements for GLP-compliant laboratories conducting environmental monitoring, pharmaceutical stability testing, and bioburden assessment in accordance with FDA 21 CFR Part 11 data integrity guidelines when integrated with optional RS485 communication and audit-trail-capable software.
Key Features
- Robust dual-door structure with high-efficiency insulation: outer door features tempered glass with anti-fog coating; inner door is stainless steel, minimizing thermal leakage during observation.
- Chamber interior constructed from mirror-finish 304 stainless steel with rounded corners (R ≥ 10 mm) for seamless cleaning and reduced microbial retention—validated for ISO 14644-1 Class 7 cleanroom-compatible operation.
- Five adjustable stainless steel shelves with load capacity up to 15 kg per shelf; shelf spacing optimized for uniform airflow distribution and minimal thermal stratification.
- Integrated UV-C germicidal lamp (254 nm) mounted at the top ceiling, activated automatically during idle cycles or manually via control interface to suppress airborne contaminants—reducing viable colony-forming units (CFU/m³) by >99.9% after 30 min exposure.
- Microprocessor-controlled PID algorithm with 0.1 °C resolution and real-time deviation compensation; includes power-failure memory retention and auto-restart functionality with parameter recovery.
- Over-temperature protection circuit with independent hardware limiter (cut-off at 70 °C) compliant with IEC 61010-1 safety standards for laboratory equipment.
- 5.7-inch TFT LCD touch interface supporting multi-parameter visualization: setpoint, actual chamber temperature, elapsed time, remaining timer duration, and system status alerts—all displayed simultaneously without menu navigation.
Sample Compatibility & Compliance
The MJ-150-I accommodates standard Petri dishes (90 mm and 150 mm), multi-well plates (6–96-well), culture flasks (T25–T225), and agar slants within its 150 L working volume. Its temperature uniformity profile (±1.5 °C at 25 °C, per ISO 16773-2 verification protocol) ensures compliance with CLSI M22-A3 for fungal susceptibility testing and EN 13697 for quantitative suspension tests. The absence of CFC/HCFC refrigerants aligns with EU F-Gas Regulation (EU) No 517/2014 and EPA SNAP Program criteria for environmentally responsible lab instrumentation.
Software & Data Management
Optional RS485 serial interface enables integration with centralized laboratory information management systems (LIMS) or SCADA platforms. When paired with Yoyilab’s certified data acquisition software (sold separately), the incubator supports time-stamped logging of temperature readings at user-defined intervals (1 s–60 min), electronic signature authentication, and 21 CFR Part 11–compliant audit trails—including operator ID, parameter changes, alarm events, and calibration history. Data export formats include CSV and PDF for regulatory submission readiness.
Applications
- Biofilm formation and antifungal resistance profiling (e.g., Candida albicans, Aspergillus niger)
- BOD₅ determination per Standard Methods 5210B using seeded dilution water incubation at 20 °C
- Mold growth rate quantification for building material testing (ASTM D3273, D6329)
- Pharmaceutical excipient stability screening under accelerated humidity-temperature stress (ICH Q1A)
- Environmental monitoring of HVAC systems and cleanrooms per ISO 14698-1
- Evaluation of antimicrobial packaging efficacy against foodborne molds (ISO 22196)
FAQ
Does the MJ-150-I support humidity control?
No—the MJ-150-I model is temperature-only. For programmable humidity (60–85% RH, ±5% RH accuracy), select the MJ-150-II variant.
Is the UV sterilization cycle automated or manual?
UV operation is user-initiated via the main interface; no automatic daily cycle is built-in, but timer-based activation can be scheduled externally via RS485 command protocol.
What is the validation support documentation available?
Factory-supplied IQ/OQ protocols, temperature mapping reports (per ISO 16773-2), and material certificates (304 SS, UL-listed components) are provided upon request.
Can this incubator be used for mammalian cell culture?
Not recommended—lack of CO₂ control, HEPA filtration, and humidity regulation precludes use for eukaryotic cell lines requiring tightly regulated physiological conditions.
What safety certifications does the unit carry?
CE-marked per EN 61010-1:2010 + A1:2019; RoHS 2011/65/EU compliant; electrical safety tested to IEC 61010-1 Annex BB for laboratory environments.
