ZiQi ZQ-80ACI Air-Jacketed CO₂ Incubator

Overview

The ZiQi ZQ-80ACI Air-Jacketed CO₂ Incubator is an engineered environmental control system designed for precise, stable, and contamination-minimized cell culture operations. It employs a convection-heated air-jacketed chamber architecture—distinct from water-jacketed alternatives—to deliver rapid thermal recovery, uniform temperature distribution, and low thermal inertia. The incubator maintains physiological conditions critical for mammalian cell propagation: tightly regulated CO₂ concentration (via non-dispersive infrared sensing), elevated humidity (>95% RH at 37°C), and tightly controlled temperature (±0.1°C setpoint accuracy, ±0.2°C uniformity across the chamber). Its design conforms to core requirements for Good Cell Culture Practice (GCCP), supporting reproducible results in applications ranging from primary cell isolation to bioprocess development and preclinical assay validation.

Key Features

• High-stability air-jacketed heating system with independent PID-controlled outer jacket and inner chamber sensors, ensuring minimal thermal overshoot and fast recovery after door opening.
• True infrared (IR) CO₂ sensor—sourced from a Tier-1 OEM supplier—provides direct, drift-free, and calibration-stable measurement across the full 0–20% range, with real-time digital display and automatic feedback-controlled gas injection.
• Dual-door configuration: outer insulated door with magnetic seal and inner high-transparency tempered glass door with integrated anti-condensation heating—enabling continuous visual monitoring without compromising chamber stability.
• Stainless steel (304 grade) interior chamber with seamless, rounded corners and electropolished finish—resistant to corrosion, compatible with standard lab disinfectants (e.g., 70% ethanol, hydrogen peroxide vapor), and compliant with ISO 14644-1 Class 5 cleanroom-compatible surface standards.
• UV-C germicidal lamp (254 nm) mounted in the chamber ceiling, programmable via timer or manual activation, validated for ≥3-log reduction of common airborne and surface contaminants (e.g., E. coli, S. aureus, fungal spores) per IEC 62471 photobiological safety guidelines.
• Microbial-grade CO₂ inlet filter (≥99.99% efficiency at ≥3 µm particle size), installed upstream of the solenoid valve, preventing particulate and microbial ingress into the chamber during gas replenishment.
• Natural evaporation humidification using a removable stainless steel water pan; humidity level is monitored indirectly via chamber temperature and pan fill status—optimized for long-term operation without condensation on optics or sensor surfaces.

Sample Compatibility & Compliance

The ZQ-80ACI supports standard tissue culture formats including T-flasks (T25–T225), Petri dishes (35–150 mm), multiwell plates (6–96-well), roller bottles, and microcarriers in suspension culture. Its chamber geometry (400 × 400 × 500 mm internal) accommodates stacked racks with vertical airflow management to minimize cross-contamination risk. The unit complies with EN 61000-6-3 (EMC emission), EN 61000-6-2 (immunity), and IEC 61010-1 (safety for laboratory equipment). While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its operational logs, parameter history, and UV cycle records are exportable in CSV format—supporting GLP/GMP-aligned documentation workflows when integrated into validated lab information management systems (LIMS).

Software & Data Management

The embedded microprocessor controller features a 4.3-inch TFT LCD interface with multilingual support (English, Spanish, Chinese), password-protected parameter editing, and configurable alarm thresholds (temperature deviation, CO₂ drift, door open duration, low water level). All operational events—including setpoint changes, UV cycles, door openings, and fault codes—are timestamped and stored locally for up to 30 days. Data export is supported via USB flash drive (no network connectivity required), generating audit-ready CSV files compatible with Excel, LabArchives, and electronic lab notebook (ELN) platforms. Optional RS-485 Modbus RTU interface enables integration into centralized building management or facility monitoring systems.

Applications

The ZQ-80ACI serves as a foundational platform for cell-based research and quality control across academic, clinical, and industrial settings. Typical use cases include maintenance of adherent and suspension human/murine cell lines (e.g., HEK293, HeLa, CHO-K1), stem cell expansion under hypoxic or normoxic CO₂ setpoints, co-culture experiments requiring stable pH buffering, and routine passage of primary isolates in diagnostic microbiology labs. Its reliability and repeatability make it suitable for ASTM E2577-compliant cell viability assays, USP ancillary materials qualification, and ISO/IEC 17025-accredited reference cell bank storage protocols—provided environmental monitoring and periodic verification (per ISO 13408-2 Annex B) are performed.

FAQ

What CO₂ sensor technology does the ZQ-80ACI use, and why is IR preferred over thermal conductivity?
It uses a factory-calibrated NDIR (non-dispersive infrared) sensor. IR detection offers superior specificity, long-term stability, and immunity to background gas interference—critical for accurate CO₂ quantification in humid, protein-rich incubator atmospheres.
Is the humidity level actively controlled or passively maintained?
Humidity is passively sustained via natural evaporation from a stainless steel water pan. No ultrasonic or steam generator is used—reducing mineral deposit risk and simplifying maintenance.
Can the UV lamp be operated while the chamber is at operating temperature?
Yes. The UV-C lamp operates independently of temperature control and may be scheduled or triggered manually without interrupting incubation conditions.
Does the unit support external data logging or network connectivity?
No built-in Ethernet or Wi-Fi. Data export is USB-only; however, RS-485 Modbus RTU is available as an optional hardware interface for SCADA or PLC integration.
What validation documentation is provided with the instrument?
Factory test reports include temperature mapping (9-point grid), CO₂ linearity verification (0%, 5%, 10%, 20%), and UV irradiance profile measurements. IQ/OQ templates aligned with ISO 13408-2 are supplied for user-executed qualification.
