Yoyilab GHP-9160 Water-Jacketed Constant Temperature Incubator

Overview

The Yoyilab GHP-9160 Water-Jacketed Constant Temperature Incubator is engineered for stable, long-term cell culture, microbial propagation, and biological sample conditioning in regulated laboratory environments. Unlike forced-air incubators, this model employs a water-jacketed heating architecture—where a sealed outer chamber filled with thermally buffered water surrounds the inner working chamber. This design delivers superior thermal mass, minimizing temperature overshoot during recovery and sustaining stable conditions during brief power interruptions. The system maintains precise setpoint control across its operational range (RT+5°C to 65°C), with a resolution of 0.1°C and uniformity of ±1.0°C at 37°C—validated under ISO 13485-aligned test protocols (empty chamber, ambient 30°C / 50% RH, no vibration or EMI). Its robust construction supports GLP-compliant workflows in pharmaceutical QC labs, academic cell biology facilities, and veterinary diagnostic centers requiring reproducible environmental control.

Key Features

• Double-walled water-jacketed chamber with high-density polyurethane insulation and reinforced silicone door gasket—ensuring low heat loss and extended thermal holdover (>2 hours after power loss at 37°C)
• Microprocessor-based PID controller with intuitive menu-driven interface; real-time display of setpoint, actual temperature, water level status, and elapsed time
• Tempered glass inner door with independent seal—enabling non-invasive observation without compromising chamber integrity or thermal stability
• Smart water-level monitoring system with dual-stage alert: visual/audible alarm triggers when jacket water falls below minimum or exceeds safe fill line
• Pressure-balanced air inlet port—eliminates back-siphoning during refilling and prevents condensation-induced contamination
• Mirror-finish stainless steel interior with radius-corner design and adjustable, autoclavable stainless steel shelving (2 standard trays included)
• Power failure recovery mode with non-volatile memory—automatically restores prior settings including temperature setpoint, timer, and alarm thresholds upon restart

Sample Compatibility & Compliance

The GHP-9160 accommodates standard tissue culture flasks (T25–T225), Petri dishes (up to 150 mm), multiwell plates, and microbiological slants without spatial restriction. Its inert stainless steel chamber and absence of catalytic surfaces make it suitable for CO₂-independent mammalian cell lines, fungal cultures, insect cell systems, and primary isolates. The unit complies with IEC 61010-1:2010 safety standards for laboratory equipment and meets essential requirements of EN 60335-1 for household and similar electrical appliances—applicable to lab-grade incubation devices. Optional accessories—including RS485 communication module (with Modbus RTU protocol), embedded thermal printer, and programmable multi-segment temperature controller—enable integration into 21 CFR Part 11–compliant data ecosystems when paired with validated software.

Software & Data Management

While the base unit operates via standalone microcontroller firmware, optional RS485 connectivity enables bidirectional communication with external SCADA or LIMS platforms. The included PC software (Windows-compatible) logs timestamped temperature readings at user-defined intervals (1–600 sec), generates CSV export files, and supports trend visualization with configurable alarm thresholds. Audit trail functionality records all parameter changes, operator logins (via password-protected access), and system events—including door openings, water level anomalies, and power cycle timestamps—supporting ALCOA+ data integrity principles. Firmware updates are performed via USB interface; version history and checksum validation ensure traceability per ISO/IEC 17025 Clause 5.9.

Applications

• Long-duration adherent and suspension cell culture under defined thermal conditions (e.g., HEK293, CHO-K1, Jurkat lines)
• Microbial growth studies for antibiotic susceptibility testing (AST) and bioburden assessment per USP <61> and ISO 11133
• Embryo development staging in reproductive biology labs using static thermal profiles
• Stability testing of biologics and excipients per ICH Q5C guidelines (temperature stress evaluation)
• Environmental simulation for agricultural seed germination assays and aquaculture larval rearing
• Quality control of probiotic formulations and starter cultures in food safety laboratories

FAQ

What is the maximum allowable ambient temperature for continuous operation?
The incubator is rated for uninterrupted use at ambient temperatures up to 30°C. Operation above this threshold may compromise temperature uniformity and extend recovery time after door opening.
Can the water jacket be filled with deionized water only?
Yes. Use of deionized or distilled water is strongly recommended to prevent mineral buildup and corrosion in the jacket cavity. Tap water is not advised due to scaling risk.
Is the GHP-9160 compatible with inert gas purging?
An optional inert gas inlet port (with integrated flowmeter) is available as an add-on accessory, enabling nitrogen or argon atmosphere control for oxygen-sensitive cultures.
How often should the water jacket be refilled or serviced?
Under normal use, water top-up frequency depends on ambient humidity and chamber cycling rate. Visual inspection every 30 days is recommended; full drain-and-refill annually or if discoloration or particulate formation occurs.
Does the unit support remote monitoring via Ethernet or Wi-Fi?
No native Ethernet or Wi-Fi interface is provided. Remote capability is limited to RS485 serial communication; third-party gateways may enable network integration but require separate validation.
