Shanghai Yiheng DHP Series Mold Incubator

Overview

The Shanghai Yiheng DHP Series Mold Incubator is a precision-engineered, natural-convection laboratory incubator designed for controlled microbial cultivation—particularly for fungi, yeasts, and other slow-growing or moisture-sensitive organisms requiring stable, low-turbulence thermal environments. Unlike forced-air incubators, the DHP series relies on gravity-driven air circulation to minimize mechanical vibration and sample desiccation, making it especially suitable for mycological studies, environmental monitoring cultures, and long-term stability testing of biological reagents where evaporation control and thermal homogeneity are critical. The unit operates within a validated temperature range of RT+5°C to 65°C, with a resolution of 0.1°C and uniformity maintained at ±0.5°C across the working chamber—meeting routine requirements for ISO/IEC 17025-accredited microbiology labs and GLP-compliant quality control workflows.

Key Features

• Mirror-polished stainless-steel interior chamber—corrosion-resistant, non-porous, and easily sanitized to prevent cross-contamination between culture batches.
• Natural convection airflow design—eliminates fan-induced turbulence and noise, preserving sample integrity and reducing evaporative loss in uncovered Petri dishes or slant cultures.
• Integrated observation window with double-glazed thermal insulation—enables real-time visual monitoring without compromising internal temperature stability.
• Fuzzy logic PID temperature controller—delivers high reproducibility with minimal overshoot; includes programmable timer (0–99 h 59 min) and auto-stop functionality.
• Independent over-temperature safety cutoff system—mechanically isolated from the main controller, providing fail-safe interruption if setpoint deviation exceeds user-defined thresholds.
• Optional multi-segment LCD programmable controller (standard on “B” models)—supports up to 7 programs, each containing 9 steps (63 total), with configurable parameters including target temperature, dwell time (0–5999 min), and ramp rates.
• Optional UV-C germicidal irradiation system (254 nm)—installed internally to decontaminate circulating air and chamber surfaces between cycles, reducing airborne fungal spore load and supporting aseptic technique compliance.

Sample Compatibility & Compliance

The DHP series accommodates standard microbiological vessels—including Petri dishes (up to 150 mm), test tubes, culture flasks, and agar slants—across chamber volumes ranging from 10 L to 210 L. Its natural convection architecture ensures compatibility with delicate filamentous fungi (e.g., Aspergillus, Penicillium) that may be disrupted by forced airflow. While not certified to IEC 61010-1 or ISO 13485 out-of-the-box, the incubator’s construction, electrical isolation, and dual-limit safety architecture align with foundational requirements for Class II laboratory equipment under EU Directive 2014/30/EU (EMC) and 2014/35/EU (LVD). Documentation packages support IQ/OQ validation protocols per ASTM E2500 and can be extended to meet FDA 21 CFR Part 11 data integrity criteria when paired with compliant software logging solutions.

Software & Data Management

The optional “B”-series LCD controller provides local data logging capability with timestamped temperature records stored onboard (non-volatile memory, 30-day buffer). Export is supported via USB interface for CSV-formatted traceability reports—suitable for audit-ready documentation in regulated environments. Though no cloud-based platform is embedded, the controller’s RS-485 port enables integration into centralized building management systems (BMS) or third-party SCADA platforms using Modbus RTU protocol. All programming interfaces adhere to IEC 62443-3-3 cybersecurity baseline principles, including password-protected parameter modification and write-locked calibration offsets.

Applications

• Mycological identification and strain maintenance in clinical, food, and pharmaceutical microbiology labs.
• Environmental mold screening per ISO 16000-18 and ASTM D3273 for indoor air quality assessment.
• Stability testing of biologics, vaccines, and diagnostic reagents under accelerated aging conditions (e.g., 40°C/75% RH simulation).
• Educational microbiology training—ideal for undergraduate labs due to operational simplicity, safety redundancy, and low maintenance overhead.
• Regulatory-compliant storage of reference cultures per USP General Chapter <61> and EP 2.6.12.

FAQ

Is the DHP series suitable for CO₂-dependent cell culture?
No. This is a dry-air, non-humidified incubator without CO₂ regulation or humidity control—intended exclusively for aerobic microbial growth and thermal stability applications.
Can the UV sterilization function operate while samples are inside?
No. The UV lamp is interlocked with the door switch and automatically deactivates upon opening; operation is restricted to empty-chamber cycles only, per IEC 62471 photobiological safety guidelines.
What validation support is provided for GMP environments?
Shanghai Yiheng supplies factory-as-tested calibration certificates (NIST-traceable), IQ/OQ templates, and sensor location diagrams—enabling users to execute qualification protocols aligned with Annex 15 of the EU GMP Guide.
Does the “B” model support remote monitoring via Ethernet or Wi-Fi?
No. Remote connectivity requires external hardware gateways; the native interface is limited to USB export and RS-485 serial communication.
What is the maximum allowable ambient temperature for continuous operation?
The unit is rated for uninterrupted use at ambient temperatures between +5°C and +35°C, as specified in IEC 61000-6-2 immunity testing conditions.
