GHP-9050 / GHP-9080 Water-Jacketed Constant Temperature Incubator

Overview

The GHP-9050 and GHP-9080 Water-Jacketed Constant Temperature Incubators are engineered for stable, uniform thermal environments essential in cell culture, microbial growth, enzyme assays, and long-term biological incubation. Unlike forced-air incubators, these models utilize a water-jacketed heating system—where temperature-controlled water circulates around the chamber walls—to deliver exceptional thermal inertia and minimal spatial gradient. This architecture ensures ±0.5 °C temperature uniformity across the working volume—even during ambient fluctuations or frequent door openings—and maintains stable conditions for up to several hours following power interruption. Designed for compliance-driven laboratories, the units operate within a validated range of RT + 5 °C to 65 °C, supporting protocols aligned with ISO 13408-1 (aseptic processing), USP <1211> (sterility assurance), and GLP-compliant cell banking workflows.

Key Features

• Water-jacketed thermal management: Provides superior temperature stability and reduced recovery time compared to air-jacketed alternatives—critical for sensitive mammalian cell lines and primary cultures.
• Mirror-finish 304 stainless steel interior: Radius-corner construction eliminates crevices, facilitating complete decontamination via vaporized hydrogen peroxide (VHP) or 70% ethanol wipe-downs; compatible with ISO 14644-1 Class 5 cleanroom maintenance routines.
• Dual-door insulation system: Outer door features magnetic seal and low-emissivity glass; inner door minimizes convective heat loss during observation—reducing chamber temperature deviation to <0.3 °C per 10-second inspection.
• Intelligent PID temperature control: Microprocessor-based regulation with adaptive tuning, real-time deviation compensation, and dual-sensor redundancy (chamber air + water jacket).
• Multi-layer safety architecture: Independent mechanical over-temperature limiter (adjustable up to 70 °C), automatic low-water-level shutoff, and simultaneous audible/visual alarm activation per IEC 61000-4-2 ESD immunity standards.
• Expandable connectivity: Optional RS485 interface supports Modbus RTU protocol for integration into centralized LabVantage or STARLIMS environmental monitoring systems; USB port enables direct data logging to external storage devices.

Sample Compatibility & Compliance

The GHP-9050 (50 L) and GHP-9080 (80 L) accommodate standard tissue culture vessels—including T-25/T-75 flasks, 6-/12-/96-well plates, Petri dishes, and roller bottles—on two fully adjustable, load-rated stainless steel shelves. The chamber’s uniform airflow-free environment prevents desiccation of open culture vessels and eliminates shear stress on adherent monolayers. Units conform to EN 61010-1:2010 (safety requirements for laboratory equipment) and meet electromagnetic compatibility (EMC) criteria per EN 61326-1:2013. Optional validation packages include IQ/OQ documentation templates aligned with FDA 21 CFR Part 11 requirements for electronic records and signatures.

Software & Data Management

When equipped with the optional RS485 interface and dedicated PC software, the incubator supports continuous temperature logging at user-defined intervals (1 sec–60 min), export in CSV or PDF format, and automated generation of calibration certificates traceable to NIST-certified references. Audit trail functionality records all parameter changes—including setpoint adjustments, alarm events, and door-open durations—with timestamp, operator ID, and reason-for-change fields. Data encryption and role-based access control comply with GDPR and HIPAA data integrity provisions for clinical research applications.

Applications

• Mammalian and insect cell line propagation (e.g., HEK293, CHO-K1, Sf9)
• Bacterial and fungal culture under non-CO₂ conditions (e.g., E. coli, S. cerevisiae, A. niger)
• Enzyme kinetics and protein stability studies requiring isothermal precision
• Seed germination and plant tissue culture in phyto-research labs
• Stability testing of biologics and excipients per ICH Q1A(R2)
• Quality control incubation for pharmaceutical raw material microbiological testing (USP <61>, <62>)

FAQ

What is the difference between water-jacketed and air-jacketed incubators?
Water-jacketed incubators use circulating heated water surrounding the chamber to achieve higher thermal mass and stability—ideal for uninterrupted long-term cultures. Air-jacketed units offer faster temperature ramping but greater susceptibility to ambient drift.
Can the GHP series be used for CO₂-sensitive applications?
No—these models lack CO₂ control and humidification systems. They are designed exclusively for ambient-air, non-humidified, constant-temperature incubation.
Is calibration certification included with purchase?
Factory calibration is performed pre-shipment using NIST-traceable thermistors. A certificate of conformance is provided; full UKAS-accredited calibration is available as an add-on service.
How often should the water jacket be refilled or replaced?
Deionized water should be replenished every 3–6 months depending on ambient humidity and usage frequency. Biocide additives are not recommended—regular visual inspection for algae or particulate formation is advised.
Does the unit support remote monitoring via Ethernet or Wi-Fi?
The base model supports only RS485 or USB. Ethernet/Wi-Fi capability requires third-party gateway integration (e.g., Moxa EDS-G205A) and is not natively embedded.
