Overview
The Jihepu GHP-9080 Water-Jacketed Constant Temperature Incubator is an engineered solution for stable, uniform thermal environments required in microbiological culture, cell propagation, enzyme activity assays, and long-term biological storage. Unlike forced-air incubators, the GHP-9080 employs a water-jacketed heating architecture—where a sealed outer chamber circulates heated water around the inner stainless-steel working compartment. This design provides superior thermal inertia and minimal temperature fluctuation (<±0.5°C), enabling uninterrupted operation during brief power interruptions and ensuring high reproducibility across extended incubation cycles (e.g., 24–168 hr). The unit operates within a validated range of RT+5°C to 65°C with 0.1°C digital resolution, making it suitable for mesophilic bacterial growth (e.g., E. coli, Bacillus subtilis), fungal cultivation, and mammalian cell line maintenance under non-CO2 conditions.
Key Features
- Microprocessor-controlled digital thermostat with real-time LED display and programmable timer (1–9999 minutes), supporting unattended overnight or multi-day protocols.
- Dual-safety interlock system: independent low-water-level detection halts heating and triggers visual alarm; optional over-temperature cut-off (configurable up to 70°C) provides redundant protection per IEC 61010-1 safety standards.
- Double-door construction: outer door is insulated steel; inner door is tempered glass with anti-fog coating—enabling continuous observation without thermal disturbance.
- 304 stainless-steel interior chamber (400 × 400 × 500 mm) resistant to corrosion from repeated sterilization, alcohol wiping, and humidified media condensation.
- Water-jacket thermal mass ensures temperature stability: measured recovery time after 15-minute door opening is <8 min to ±0.3°C deviation at 37°C (tested per ISO 13485 Annex A guidelines).
Sample Compatibility & Compliance
The GHP-9080 accommodates standard Petri dishes (up to 150 mm), multi-well plates (6–96-well), culture flasks (T25–T175), and glass test tubes—all supported on three adjustable, load-rated stainless-steel shelves (max. 15 kg total distributed load). Its water-jacketed design eliminates airflow-induced desiccation, preserving moisture integrity for agar-based media and suspension cultures. While not certified for GLP/GMP production environments, the unit meets essential electrical safety (IEC 61010-1), electromagnetic compatibility (IEC 61326-1), and laboratory equipment labeling requirements (CE marking applicable for EU export). Documentation includes factory calibration report traceable to NIM (National Institute of Metrology, China) standards.
Software & Data Management
The GHP-9080 operates via embedded firmware—no external PC or proprietary software required. All operational parameters (setpoint, actual temperature, elapsed time, alarm status) are logged internally with timestamping and retained for ≥30 days. Optional RS-232 interface (available upon request) enables serial data export to third-party LIMS or Excel-based tracking systems. Audit trail functionality supports basic 21 CFR Part 11 readiness when paired with institutional electronic signature policies—though full compliance requires site-specific validation (IQ/OQ/PQ) performed by end-user QA teams.
Applications
- Microbiological quality control in food, pharmaceutical, and environmental labs (e.g., APC, coliform, yeast/mold enumeration per ISO 4833-1, AOAC 977.27).
- Plant tissue culture initiation and callus maintenance (25–28°C range).
- Enzyme kinetics studies requiring precise thermal stabilization (e.g., amylase, protease assays).
- Stability testing of diagnostic reagents and biologics under accelerated conditions (ICH Q1A).
- Teaching laboratories: ideal for undergraduate microbiology, molecular biology, and biotechnology curricula due to robustness, intuitive interface, and service-friendly modular design.
FAQ
What is the recommended maintenance interval for the water jacket?
Drain, clean, and refill the water jacket every 3–6 months using deionized water to prevent mineral buildup and microbial growth in stagnant water.
Can this incubator be used for CO₂-dependent cell cultures?
No—the GHP-9080 lacks CO₂ regulation, humidity control, and HEPA filtration; it is intended for ambient-air applications only.
Is calibration certificate included with shipment?
A factory-issued calibration report (covering temperature uniformity and accuracy at 37°C and 55°C) is provided; NIST-traceable field calibration is available as a value-added service.
Does the unit support remote monitoring via Ethernet or Wi-Fi?
Not natively—only RS-232 serial output is integrated; Ethernet/Wi-Fi modules require third-party hardware integration and are not supported by default firmware.
