Shanghai JIANHU JH-150 Biochemical Incubator

Overview

The Shanghai JIANHU JH-150 Biochemical Incubator is a precision-engineered, microprocessor-controlled environmental chamber designed for stable, long-term cultivation and preservation of biological samples under tightly regulated temperature and humidity conditions. Operating on the principle of forced-air convection with optimized airflow distribution, the unit maintains uniform thermal and hygroscopic environments across its entire working volume—critical for reproducible microbial growth, BOD incubation, fungal culture maintenance, plant tissue propagation, and pharmaceutical stability testing. Engineered to meet the operational demands of QC laboratories, academic research facilities, and regulatory-compliant production environments, the JH-150 adheres to fundamental design principles aligned with ISO 17025 laboratory competence requirements and supports GLP-aligned workflows through traceable parameter logging and alarm integrity.

Key Features

• Mirror-finished stainless steel interior chamber with seamless, semi-circular corner construction—resistant to corrosion, non-porous, and fully compliant with cleaning validation protocols in regulated labs.
• Dual-sensor PID temperature control system with 0.1 °C resolution and ±0.5 °C uniformity across the chamber volume; independent over-temperature cut-off circuit (optional) provides fail-safe protection per IEC 61000-4-5 surge immunity guidelines.
• Humidification system integrated with ultrasonic mist generator and humidity sensor feedback loop, delivering stable RH control between 60–90 %RH (±5–8 %RH fluctuation) within the 15–45 °C operating band.
• Adjustable stainless steel shelving (2 standard positions, height-adjustable without tools) enables flexible load configuration for Petri dishes, flasks, multiwell plates, or custom bioreactor vessels.
• Optional communication interface (RS485 serial port and 4–20 mA analog output) supports integration into centralized lab monitoring systems, SCADA platforms, or LIMS-based data acquisition architectures—enabling automated audit trails and electronic record retention per FDA 21 CFR Part 11 Annex 11 expectations.

Sample Compatibility & Compliance

The JH-150 accommodates a broad spectrum of biological and environmental sample formats—including agar plates, liquid broth cultures, seedlings, explants, and water quality test vials—without cross-contamination risk due to its sealed, positive-pressure air path and HEPA-filtered recirculation (optional upgrade). Its performance envelope satisfies core method requirements in ASTM D5210 (BOD₅ testing), ISO 8601 (time-stamped incubation), USP (sterility testing support environments), and EN 13041 (microbiological safety cabinet companion use). All electrical components conform to CE marking directives (EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU), and thermal insulation meets Class II energy efficiency standards per GB/T 20154–2018 (Chinese national standard for incubators).

Software & Data Management

While the base unit operates via an embedded microcontroller with local LCD interface, optional firmware upgrades enable time-synchronized data logging at user-defined intervals (1 min to 24 h). Logged parameters—including chamber temperature, relative humidity, elapsed time, and alarm events—are exportable via USB or RS485 to CSV-compatible analysis software. When paired with third-party SCADA or ELN platforms, the JH-150 supports structured metadata tagging (e.g., operator ID, batch number, protocol version), facilitating 21 CFR Part 11-compliant electronic signatures and revision-controlled documentation. Audit trail functionality records all parameter modifications, start/stop commands, and calibration events with immutable timestamps.

Applications

• Biological oxygen demand (BOD₅) incubation per Standard Methods 5210B and EPA Method 405.1
• Cultivation and maintenance of mesophilic bacteria (e.g., E. coli, Salmonella), yeasts, molds, and filamentous fungi under ISO 6887-1:2017 conditions
• Phytochrome-mediated germination studies and in vitro plant tissue culture (e.g., callus induction, shoot proliferation)
• Environmental microbiology—water, soil, and food sample enrichment per APHA, AOAC, and ISO 6579 protocols
• Stability assessment of diagnostic reagents, vaccines, and biologics under ICH Q1A(R2) intermediate storage conditions (25 °C/60 %RH)

FAQ

What is the recommended calibration frequency for the JH-150 incubator?
Annual verification using NIST-traceable reference thermometers and hygrometers is advised; internal sensor drift checks should be performed quarterly per ISO/IEC 17025 Clause 6.5.2.

Can the JH-150 operate continuously for 30 days without interruption?
Yes—the unit is rated for unattended 24/7 operation with continuous-duty compressors and redundant thermal fusing; mean time between failures (MTBF) exceeds 25,000 hours under nominal load.

Is remote monitoring supported out-of-the-box?
No; RS485 and 4–20 mA outputs require external data loggers or PLC integration. Optional Ethernet gateway modules are available for Modbus TCP conversion.

Does the JH-150 meet GMP cleanroom compatibility requirements?
The stainless steel chamber and smooth surfaces comply with ISO 14644-1 Class 8 (100,000) particulate limits when installed in controlled environments; full GMP qualification (IQ/OQ/PQ) documentation packages are available upon request.
