Mold Incubator MTN-80 by ALISN

Overview

The ALISN MTN-80 Mold Incubator is a precision-controlled environmental test chamber engineered specifically for standardized mycological growth assessment and long-term fungal culture maintenance. Designed in accordance with ISO 846 (Plastics — Evaluation of the effect of microorganisms), ASTM G21 (Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi), and relevant sections of GB/T 2423.16 (Environmental Testing – Part 2: Test Methods – Test J: Mold Growth), the MTN-80 provides stable, programmable temperature and humidity conditions essential for reproducible mold propagation studies. Its sealed double-wall insulation structure, combined with PID-regulated heating and ultrasonic humidification, ensures ±0.5 °C temperature uniformity and ±3% RH stability across the entire 80 L working volume—critical parameters for evaluating material susceptibility to fungal colonization under controlled acceleration protocols.

Key Features

• 80 L stainless steel inner chamber (SUS304) with seamless welding and rounded corners for easy decontamination and compliance with GLP cleaning validation requirements
• Dual-sensor feedback loop: high-accuracy capacitive RH sensor (0–99.9% RH, ±2% RH accuracy) and PT100 temperature probe (−5 to 70 °C, ±0.3 °C accuracy)
• Intelligent PID control system with 30-segment programmable cycle capability, supporting ramp-hold profiles for simulating seasonal or tropical exposure conditions
• UV-C germicidal lamp (254 nm, 15 W) integrated into the chamber ceiling for pre-test sterilization and post-cycle bio-decontamination
• Over-temperature and over-humidity cut-off protection, independent mechanical safety thermostat, and door-open alarm with audible/visual notification
• RS-485 communication interface compliant with Modbus RTU protocol for integration into centralized lab monitoring systems

Sample Compatibility & Compliance

The MTN-80 accommodates standard petri dishes (up to 150 mm diameter), multi-well plates, polymer coupons (50 × 50 mm), textile swatches, and coated substrates without requiring custom fixtures. Chamber dimensions (W × D × H: 450 × 450 × 400 mm) allow vertical stacking of up to four sample tiers using adjustable stainless steel shelves. All materials in contact with the test environment—including gaskets, sensors, and humidifier components—meet USP Class VI biocompatibility requirements. The unit is CE-marked per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and supports audit-ready documentation packages aligned with ISO/IEC 17025 laboratory accreditation criteria.

Software & Data Management

The embedded controller logs timestamped temperature and humidity readings at user-defined intervals (1 min to 24 h), storing up to 12 months of data internally. Export is supported via USB flash drive in CSV format compatible with LIMS platforms and statistical analysis tools (e.g., JMP, Minitab). Optional PC-based software (ALISN EnviroLog v3.2) enables real-time remote monitoring, alarm email notifications (SMTP), electronic signature support for test record approval, and 21 CFR Part 11-compliant audit trail generation—including operator ID, parameter changes, and event timestamps. Data integrity safeguards include write-protection modes and cyclic redundancy check (CRC) verification on all exported files.

Applications

• Accelerated mold resistance testing of construction materials (paints, sealants, gypsum board, insulation)
• Biodegradability screening of biopolymers and compostable packaging per ISO 20200 and ASTM D6400
• Pharmaceutical excipient stability evaluation under high-humidity stress conditions (ICH Q1B)
• Microbiological challenge studies for medical device packaging validation (ISO 11607-1)
• Academic research in mycology, including spore germination kinetics and hyphal growth rate quantification under defined microclimates
• Quality control of HVAC filter media and antimicrobial-treated textiles per AATCC TM30 and ISO 20743

FAQ

What is the maximum operating humidity range of the MTN-80?
The chamber achieves 20–95% RH at 25–40 °C; extended operation above 95% RH is not recommended due to condensation risk and sensor drift.
Does the MTN-80 support continuous data logging during power interruption?
Yes—the internal memory retains logged data for up to 72 hours without external power; full recovery occurs automatically upon reconnection.
Can third-party calibration certificates be issued for the MTN-80?
Yes—ALISN partners with CNAS-accredited calibration laboratories; NIST-traceable certificates for temperature and RH sensors are available upon request.
Is the UV-C lamp ozone-free?
Yes—the low-pressure mercury lamp emits exclusively at 254 nm with no detectable ozone generation (<0.01 ppm), meeting OSHA PEL standards for occupied-space decontamination cycles.
What maintenance intervals are recommended for routine operation?
Humidifier tank cleaning every 7 days, HEPA pre-filter replacement every 6 months, and annual sensor recalibration—documented in the included Maintenance Logbook per ISO/IEC 17025 clause 6.4.10.
