Zhicheng ZXGP-A2160 Water-Jacketed Programmable Incubator with 10-Stage Temperature Profile Control

Overview

The Zhicheng ZXGP-A2160 is a precision-engineered water-jacketed constant temperature incubator designed for long-term, high-stability thermal environments in regulated life science laboratories. Unlike forced-air convection units, its dual-wall water-jacket construction provides superior thermal inertia and minimal temperature drift—critical for sensitive cell culture, microbial propagation, and stability testing where ambient fluctuations must be decoupled from chamber dynamics. The system employs fuzzy logic control architecture to continuously modulate heating output based on real-time feedback from high-response platinum resistance thermometers (PT100-class equivalent), ensuring robust setpoint adherence across the full operating range of ambient +5°C to 60°C. With a nominal chamber volume of 160 L and optimized internal geometry—including mirror-finish stainless steel interior walls, electropolished stainless steel shelving, and a dual-door configuration featuring an inner tempered glass observation window—the ZXGP-A2160 balances operational integrity with ergonomic access and visual monitoring.

Key Features

• 10-segment, 18-step programmable temperature profiling—enabling complex thermal protocols such as ramp-hold-cool cycles, multi-stage fermentation schedules, or accelerated stability studies.
• Fuzzy logic temperature control algorithm delivering ≤ ±0.5°C fluctuation and ≤ ±1.0°C uniformity at 37°C—validated per ISO 13408-1 Annex B and ASTM E2924-19 guidelines for incubator performance verification.
• Dual independent safety layers: adjustable overtemperature prevention (30–80°C range) and fixed overheat cutoff—both electrically isolated from main control circuitry per IEC 61010-1 Class II requirements.
• Comprehensive self-diagnostic suite including power failure detection, sensor open/short fault reporting, upper/lower limit violation alerts, and automatic recovery upon mains restoration (with configurable delay).
• Top-mounted micro-airflow circulation system minimizing turbulence while ensuring homogeneous heat distribution—validated via 9-point mapping per USP environmental uniformity protocols.
• LCD interface with password-protected parameter editing, temperature display calibration offset adjustment, and real-time clock synchronization for time-stamped event logging.

Sample Compatibility & Compliance

The ZXGP-A2160 accommodates standard tissue culture flasks (T25–T225), Petri dishes (up to 150 mm), multiwell plates, serum bottles, and sealed vials without compromising sterility or thermal fidelity. Its seamless, crevice-free stainless steel interior and electropolished shelving meet ISO 14644-1 Class 5 cleanroom-compatible surface finish standards. The unit supports GLP/GMP-aligned workflows through traceable parameter memory (retains all user-defined settings after power cycling), RS-232 serial communication for external data acquisition, and embedded thermal printer output for immediate hard-copy record generation. While not FDA 21 CFR Part 11 certified out-of-the-box, its audit-ready event log structure—including timestamped alarms, setpoint changes, and door-open durations—facilitates validation documentation for ISO 17025-accredited labs and pharmaceutical QC environments.

Software & Data Management

No proprietary software installation is required. All operational parameters—including segment definitions, dwell times, ramp rates, and alarm thresholds—are configured directly via the front-panel LCD interface. RS-232 connectivity enables integration with laboratory information management systems (LIMS) or custom SCADA platforms using ASCII-based command protocols (e.g., “GET_TEMP”, “SET_SEG1”, “READ_ALARM”). The built-in thermal printer outputs chronological records of chamber temperature, active segment number, elapsed time, and triggered alarms—formatted for inclusion in batch records per EU Annex 11 and WHO TRS 961 Annex 5 expectations. Parameter memory retains up to 10 distinct program profiles with individual password protection (4-digit numeric), supporting multi-user lab environments with role-based access control.

Applications

This incubator serves critical functions across regulatory-compliant and research-intensive domains: mammalian and insect cell line maintenance (e.g., CHO, HEK293, Sf9); bacterial and fungal culture under defined thermal regimens; enzyme activity assays requiring precise thermal staging; stability testing of biologics, vaccines, and excipients per ICH Q1A(R2); storage of sera, growth media, and diagnostic reagents; and environmental simulation for agricultural seed germination or soil microbiome studies. Its water-jacket design makes it especially suitable for facilities with unstable HVAC conditions or frequent door-opening routines—common in shared core facilities and teaching laboratories.

FAQ

What is the difference between water-jacketed and air-jacketed incubators?
Water-jacketed models provide greater thermal mass and reduced sensitivity to ambient temperature shifts—ideal for uncontrolled lab spaces or applications demanding ultra-stable setpoints over extended periods.
Can the ZXGP-A2160 be validated for GMP use?
Yes—its repeatable temperature performance, independent safety circuits, and event-logged operational history support IQ/OQ/PQ protocol development per ASTM E2924 and ISO 13408-1.
Is the RS-232 interface compatible with modern Windows/macOS systems?
Yes, using standard USB-to-serial adapters and terminal emulation software (e.g., PuTTY, Tera Term) with configurable baud rate (default: 9600, 8N1).
How many shelves can be installed simultaneously?
Two shelves are standard; up to four may be installed—subject to minimum 75 mm clearance between shelves for airflow compliance.
Does the unit include a calibration certificate?
Factory calibration is performed at 37°C using NIST-traceable reference probes; optional UKAS-accredited calibration certificates are available upon request.
