Overview
The Yi Heng BPMJ Series Mold Incubator is a precision-controlled, refrigerated incubation system engineered for reliable long-term fungal culture, mycological research, and controlled-environment microbiology applications. Designed in accordance with ISO 14644 cleanroom principles and aligned with GLP-compliant laboratory practices, the BPMJ series employs a dual-stage cooling architecture with eco-friendly non-CFC refrigerants to maintain stable sub-ambient to elevated temperatures (−5 to 70 °C). Its core thermal management integrates a high-efficiency hermetic compressor, a microprocessor-regulated air circulation system with variable-speed fans, and an optimized laminar airflow path—ensuring minimal thermal stratification and reproducible environmental conditions across the entire chamber volume. Unlike general-purpose biochemical incubators, the BPMJ series incorporates structural and functional adaptations specific to mold cultivation: UV-C germicidal irradiation (optional), enhanced condensation control, and extended low-temperature stability essential for sporulation inhibition and selective fungal growth.
Key Features
- Non-CFC refrigeration system compliant with Montreal Protocol standards and EU F-Gas Regulation (EU No. 517/2014)
- Intelligent PID temperature controller with adaptive tuning, ±0.1 °C setpoint repeatability, and programmable ramp/soak profiles
- Variable-speed fan control: automatically modulates airflow velocity during steady-state operation to minimize sample desiccation while maintaining uniformity (±1.5 °C)
- Electropolished mirror-finish stainless-steel interior (AISI 304), seamless quarter-radius corners, and removable adjustable shelving for full cleanability and ISO 13485-compatible decontamination
- 25 mm diameter external access port (left-side mounted) for sensor cabling, gas inlet lines, or external monitoring interfaces
- Multi-segment programmable controller supporting up to 7 programs × 9 steps (63 total steps); each step configurable for temperature, fan speed, duration (0–5999 min), and ramp rate
- Real-time fault diagnostics displayed on backlit LCD interface—including compressor overload, sensor failure, door-open alert, and overtemperature events
- Dual independent safety systems: mechanical high-limit cutout and electronic overtemperature alarm with audible/visual notification (IEC 61010-1 Class II compliance)
Sample Compatibility & Compliance
The BPMJ series accommodates standard Petri dishes (up to 150 mm), multi-well plates, slant tubes, and agar-filled Erlenmeyer flasks without spatial interference. Internal dimensions support ISO/IEC 17025-compliant placement of NIST-traceable reference sensors for validation. The UV-C lamp (254 nm, optional) is CE-marked and calibrated to deliver ≥100 µW/cm² irradiance at 1 m distance—validated per ISO 15714 for microbial reduction efficacy against Aspergillus niger and Penicillium chrysogenum. All models meet EN 61000-6-3 (EMC emission) and EN 61000-6-2 (immunity) requirements. Documentation includes factory calibration certificates (traceable to CNAS-accredited labs), IQ/OQ templates, and materials declarations per RoHS 2011/65/EU.
Software & Data Management
An optional RS-485 interface enables integration into centralized Lab Information Management Systems (LIMS) via Modbus RTU protocol. USB host port supports direct data export to FAT32-formatted USB drives, recording timestamped temperature logs (1-min resolution), fan speed status, and alarm history for ≥30 days. Optional thermal printer module provides real-time hardcopy output compliant with FDA 21 CFR Part 11 Annex 11 audit trail requirements—retaining operator ID, event timestamps, and parameter change logs. Firmware supports firmware update via USB and includes password-protected configuration modes to enforce SOP adherence.
Applications
- Fungal isolation and identification per CLSI M38-A3 guidelines
- Mycotoxin production studies under controlled humidity and temperature gradients
- Antifungal susceptibility testing (AFST) using EUCAST E.Def 9.3 methodology
- Environmental monitoring of cleanrooms and pharmaceutical manufacturing suites (ISO 14644-1 Class 5–8)
- Long-term stability testing of biologics and probiotic formulations
- Teaching laboratories for undergraduate mycology and industrial microbiology curricula
FAQ
Does the BPMJ series support humidification?
No—this model is a dry-air mold incubator. Humidity control requires integration with an external saturated salt system or dedicated humidified incubator (e.g., Yi Heng HP series).
Can the UV lamp operate while samples are inside?
No—UV sterilization must be performed with the chamber empty and door interlocked. Automatic shutoff is triggered upon door opening.
Is validation documentation provided?
Yes—each unit ships with a Factory Acceptance Test (FAT) report, calibration certificate (temperature sensor traceable to national standards), and IQ/OQ protocol templates compatible with GMP/GLP environments.
What is the maximum ambient temperature for rated performance?
The incubator maintains specified uniformity only when installed in environments ≤35 °C; sustained operation above this threshold may compromise compressor duty cycle and temperature stability.
Are replacement shelves and UV lamps available as spare parts?
Yes—stainless-steel shelves (part no. BPMJ-SH-01), UV-C tubes (GPH15T5L/4P), and door gaskets (BPMJ-GSK-02) are stocked globally through authorized distributors.
