Labotery MJL Series Mold Incubator

Overview

The Labotery MJL Series Mold Incubator is a precision-controlled, humidity-capable environmental chamber engineered for the reliable cultivation and maintenance of filamentous fungi, yeasts, and other moisture-sensitive microorganisms under standardized laboratory conditions. Designed in accordance with ISO 21527-1 (microbiological methods for food and animal feeding stuffs — enumeration of yeasts and molds), this incubator supports critical applications including fungal isolation, spore germination studies, mycotoxin production assays, and stability testing of pharmaceutical excipients susceptible to mold contamination. Its dual-mode operation—offering both non-humidified (0–65 °C) and humidified (10–65 °C) temperature control—enables method flexibility across regulatory-compliant workflows in clinical microbiology, pharmaceutical quality control (QC), and environmental monitoring laboratories. The system employs a CFC-free R134a refrigeration circuit, combined with PID-based thermal regulation and independent ultrasonic humidification, ensuring stable, repeatable environmental profiles essential for GLP- and GMP-aligned experiments.

Key Features

• Environmentally compliant refrigeration using ozone-safe R134a refrigerant, meeting international standards for sustainable lab equipment.
• Electropolished stainless-steel interior with seamless arc-corner construction, facilitating ISO 14644-compliant cleaning and minimizing microbial retention points.
• Centrifugal forced-air circulation system with infinitely variable fan speed control, delivering uniform temperature distribution (±0.3 °C) and minimizing vertical thermal gradients.
• Integrated ultrasonic humidifier with large-capacity water reservoir and intelligent misting algorithm, maintaining 40–90 %RH with ±5–8 %RH accuracy under steady-state conditions.
• Dual-layer magnetic door seal and UV-C germicidal lamp (254 nm) for routine decontamination between runs, supporting biosafety Level 1 (BSL-1) containment practices.
• 10.1-inch color TFT-LCD touchscreen interface with intuitive navigation, real-time multi-parameter display (temperature, humidity, elapsed time, setpoints), and built-in data logging.
• Programmable temperature correction function and user-defined alarm thresholds for over-temperature, under-humidity, and door-open events.
• Left-side 30-mm access port with silicone gasket, enabling integration with external sensors, gas supply lines, or data acquisition systems without compromising chamber integrity.
• Front-accessible dust filter for condenser and evaporator units, simplifying preventive maintenance per manufacturer-recommended service intervals.

Sample Compatibility & Compliance

The MJL series accommodates standard Petri dishes (90 mm and 150 mm), slant tubes, multi-well plates, and custom agar-filled containers up to 15 kg per shelf (two adjustable shelves included). All models are compatible with ASTM D3273 (Standard Test Method for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental Chamber) and support validation protocols aligned with USP and . Humidity control performance has been verified per ICH Q5C guidelines for stability testing of biopharmaceuticals under intermediate storage conditions. Electrical safety complies with IEC 61010-1; EMC conformity meets EN 61326-1 for laboratory use in regulated environments.

Software & Data Management

Standard configuration includes embedded firmware with 30-segment programmable temperature/humidity profiles, supporting stepwise ramp-and-soak cycles for simulated seasonal stress testing or accelerated aging. Optional upgrades include RS-485 Modbus RTU interface for SCADA integration, USB 2.0 port for CSV-formatted data export (timestamped temperature/humidity logs at user-selectable intervals), and optional thermal printer module for hard-copy audit trails. Firmware supports electronic signature-enabled parameter locking and full audit trail functionality—including operator ID, timestamp, and value change history—meeting FDA 21 CFR Part 11 requirements when deployed with validated network authentication infrastructure.

Applications

• Fungal enumeration and identification in food, water, and pharmaceutical raw materials per ISO 7954 and AOAC 997.01.
• Mycotoxin biosynthesis studies requiring precise hygrothermal control (e.g., aflatoxin B1 production by Aspergillus flavus at 25–30 °C / 85 %RH).
• Stability assessment of sterile products stored under high-humidity conditions per ICH Q1A(R2).
• Biodeterioration testing of building materials, textiles, and polymer composites per ASTM G21.
• Plant pathology research involving obligate fungal pathogens requiring extended incubation under controlled dew-point conditions.
• Validation of disinfectant efficacy against spore-forming molds in healthcare facility environmental monitoring programs.

FAQ

What is the recommended calibration frequency for temperature and humidity sensors?
Annual traceable calibration is advised; internal sensors support two-point adjustment via front-panel menu using NIST-traceable reference probes.

Can the incubator operate continuously at 65 °C with 90 %RH?
Yes—continuous operation at maximum setpoints is supported, though sustained use above 55 °C/85 %RH may reduce humidifier service life; consult maintenance schedule for wick replacement intervals.

Is remote monitoring possible without third-party software?
Basic status polling (temperature/humidity/alarms) is available via Modbus RTU; full graphical remote supervision requires optional Labotery Link™ client application.

Does the unit meet UL or CE certification requirements?
All MJL models carry CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD); UL 61010-1 listing is available upon request for North American installations.

How is condensation managed during high-humidity cycling?
Active condensate evaporation via heated drain pan and integrated vapor recovery loop prevents pooling and maintains chamber floor dryness during RH transitions.
