Overview
The ALISN MTN-150 Mold Incubation Chamber is a purpose-built environmental test chamber engineered for controlled fungal growth, stability testing, and long-term microbiological culture maintenance under ISO 14644-1 Class 7 cleanroom-compatible conditions. Unlike general-purpose incubators, the MTN-150 integrates mold-specific thermal management architecture—featuring dual-stage refrigeration with SECOP compressors and EBM condenser fans—to sustain precise low-temperature operation down to −10 °C while maintaining tight uniformity (±0.2–0.5 °C) across its 150 L working volume. Its control core employs adaptive PID-fuzzy hybrid logic, enabling robust disturbance rejection during door openings and load changes—critical for reproducible mycological assays per ASTM D3273 (Standard Test Method for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental Chamber) and ISO 846 (Plastics—Evaluation of the Action of Fungi). The chamber complies with ICH Q5C stability protocol requirements for intermediate and accelerated storage conditions and supports GLP-compliant documentation workflows through embedded audit trail and electronic record integrity safeguards.
Key Features
- True-color 4.3-inch capacitive touchscreen interface with intuitive icon-driven navigation and real-time graphical trend display
- Monolithic polyurethane insulation (≥60 mm) applied via high-pressure foaming—eliminating thermal bridging and enhancing structural rigidity
- HERAEUS Class A Pt100 RTD sensors calibrated at three points (0 °C, 25 °C, 60 °C); traceable to NIST standards with zero-drift performance over 5+ years
- UV-C sterilization module (254 nm, 15 W) integrated into ceiling assembly with automatic interlock disabling during door opening
- Dual-door configuration: outer insulated door with magnetic seal + inner tempered glass door enabling non-invasive visual monitoring without thermal perturbation
- Modular stainless-steel shelving system (standard: 2 shelves; optional: up to 5 levels), load-rated to 15 kg/shelf, compatible with ISO/IEC 17025-compliant calibration trays
- Environmental sealing: IP54-rated enclosure with Ø50 mm silicone-gasketed feedthrough port for external sensor integration or gas purging lines
Sample Compatibility & Compliance
The MTN-150 accommodates standard microbiological formats including Petri dishes (90–150 mm), slant tubes, broth vials, and multi-well plates—optimized for Aspergillus niger, Penicillium chrysogenum, Trichoderma viride, and other ISO 846 reference strains. Its validated temperature profile meets EN 61000-6-3 (EMC emissions) and EN 61000-6-2 (immunity) requirements. All firmware and data handling routines conform to FDA 21 CFR Part 11 Annex 11 principles: electronic signatures, role-based access control, immutable audit logs, and cryptographic checksums for exported USB archives. Calibration certificates include uncertainty budgets per ISO/IEC 17025:2017 Clause 7.8.3.
Software & Data Management
- Onboard data logger stores temperature readings at user-selectable intervals (1 s–60 min), retaining ≥3 years of continuous records in FAT32-formatted binary files
- Audit trail captures timestamps, operator IDs, parameter modifications, alarm triggers, and system state transitions—exportable as CSV with SHA-256 hash verification
- USB host port enables direct firmware updates and secure data offload; USB device mode allows connection to external PCs for remote monitoring via Modbus RTU (RS485)
- Five-tier permission hierarchy: Administrator, Supervisor, Technician, Analyst, Viewer—each with configurable rights over setpoint editing, log export, sterilization activation, and user account management
- Firmware supports dual-language UI switching (English/Chinese) without reboot; language selection persists across power cycles
Applications
The MTN-150 serves critical functions in pharmaceutical quality control (QC) laboratories conducting USP <71> sterility test environmental monitoring, bioburden assessment per ISO 11737-1, and antifungal efficacy validation. It is routinely deployed in food safety labs performing ISO 21527-1 yeast and mold enumeration, environmental health agencies executing EPA Method 1603 compliance testing, and academic research groups studying fungal secondary metabolite production kinetics under regulated humidity-temperature gradients. Its −10 °C capability supports cold-tolerant strain preservation, while extended 65 °C operation enables accelerated aging studies of polymer-based medical devices per ISO 10993-12.
FAQ
Does the MTN-150 support humidity control?
Humidity regulation is not integrated into the base MTN-150 configuration. For combined temp/humidity mold testing, consult the ALISN MTH series chambers with programmable RH range 30–95% ±3% RH.
Is calibration certificate included with shipment?
Yes—a factory-issued calibration report (traceable to CNAS-accredited lab) is provided, covering temperature uniformity and stability at three points (−10 °C, 25 °C, 60 °C) per ISO 17025 requirements.
Can the audit trail be disabled for internal use?
No. Audit trail logging is mandatory and non-removable per design—aligned with 21 CFR Part 11 §11.10(e) and EU Annex 11 §4.2 requirements for computerized systems in GxP environments.
What is the maximum allowable ambient temperature for continuous operation?
Rated ambient operating range is 5–35 °C. For sustained 65 °C internal setpoints, ambient must remain ≤28 °C to ensure compressor longevity and thermal stability compliance.
Are third-party software integrations supported?
Native Modbus RTU (RS485) and ASCII protocol (RS232) drivers are supplied for integration with LabArchives, Empower, or custom SCADA systems. OPC UA support requires optional ALISN Gateway Module (order code: AGW-MTN).
