CZGY CHP-80S Carbon Dioxide Incubator

Overview

The CZGY CHP-80S Carbon Dioxide Incubator is a precision-engineered, water-jacketed environmental chamber designed for reliable, contamination-controlled cell and tissue culture in academic, clinical, and industrial life science laboratories. It operates on the principle of maintaining a stable, physiologically relevant atmosphere—comprising tightly regulated CO₂ concentration (0–20 %), temperature (RT+5 to 60 °C), and internal humidity via natural evaporation—thereby mimicking the in vivo conditions required for mammalian cell proliferation, stem cell expansion, primary culture maintenance, and sensitive co-culture systems. Its water-jacketed thermal architecture ensures superior temperature stability and reduced ambient sensitivity compared to air-jacketed alternatives, making it particularly suitable for long-term experiments where thermal drift must be minimized. The incubator complies with fundamental design expectations outlined in ISO 13408-1 (aseptic processing of pharmaceuticals) and supports Good Laboratory Practice (GLP) workflows through traceable parameter control and alarm logging.

Key Features

• Water-jacketed heating system for enhanced thermal uniformity (±1 °C) and resilience against room temperature fluctuations
• High-precision infrared CO₂ sensor with ±0.1 % accuracy and rapid recovery time (≤ concentration × 1.2 minutes), ensuring consistent bicarbonate-buffered media pH
• Antibacterial stainless-steel interior with seamless, radius-rounded corners and removable, autoclavable shelving for effective cleaning and decontamination
• Heated inner glass door prevents condensation formation—eliminating moisture-mediated microbial ingress pathways during routine access
• Integrated UV germicidal lamp mounted on rear chamber wall, enabling scheduled sterilization of circulating air and humidification tray vapor
• Microbial-grade inlet filter (HEPA equivalent, ≥99.99 % retention of ≥0.3 µm particles) installed inline with CO₂ supply to prevent exogenous contamination
• LCD-based microprocessor controller with real-time digital display of temperature, CO₂ concentration, and operational status indicators
• Comprehensive safety suite including over-temperature cut-off, low-water-level detection, CO₂ deviation alarm, and door-open warning
• Optional RS-485 serial interface for external data acquisition, audit trail generation, and integration into centralized lab monitoring systems

Sample Compatibility & Compliance

The CHP-80S accommodates standard T-flasks (up to 175 cm²), multi-well plates (6–96-well), Petri dishes, roller bottles, and custom culture vessels up to 500 × 400 × 400 mm internal dimensions. Its design supports adherence to core biosafety and quality assurance frameworks: the heated door and UV sterilization protocol align with CLSI M29-A3 guidelines for minimizing cross-contamination; the CO₂ sensor calibration traceability and alarm logging capability facilitate compliance with FDA 21 CFR Part 11 requirements when paired with validated third-party data logging software; and its construction materials meet USP extractables criteria for non-reactive surfaces in cell therapy applications. While the unit does not include active humidity control, its natural evaporation system—coupled with a stainless-steel water reservoir—maintains >95 % RH under typical operating conditions (37 °C, 5 % CO₂), sufficient for most adherent and suspension cultures.

Software & Data Management

The embedded controller records operational events—including temperature excursions, CO₂ deviations, door openings, and alarm activations—in non-volatile memory with timestamping. When equipped with the optional RS-485 module, the incubator transmits real-time parameters (temperature, CO₂ %, elapsed time) to external PCs or PLCs using Modbus RTU protocol. This enables integration with laboratory information management systems (LIMS), electronic lab notebooks (ELN), or SCADA platforms for automated audit trail generation. Data export is compatible with CSV and Excel formats, supporting retrospective analysis and regulatory submission packages. Firmware updates are performed via USB interface, ensuring long-term maintainability without hardware replacement.

Applications

• Mammalian cell line propagation (e.g., HEK293, CHO, HeLa) under standardized 37 °C / 5 % CO₂ conditions
• Primary neuronal, epithelial, and endothelial cell culture requiring high sterility integrity and minimal thermal perturbation
• Stem cell maintenance and differentiation assays where atmospheric consistency directly impacts pluripotency markers
• Virology research involving viral titration, plaque assays, and host-pathogen interaction studies
• Regenerative medicine workflows including scaffold-based 3D culture and organoid development
• Quality control testing of biologics, vaccines, and monoclonal antibodies per ICH Q5A and Q5B guidelines
• Teaching laboratories conducting foundational cell biology and pharmacology experiments

FAQ

Does the CHP-80S include active humidity control?
No—it relies on natural evaporation from a stainless-steel water pan. Relative humidity typically exceeds 95 % at 37 °C and 5 % CO₂, which meets requirements for most routine cell culture protocols.
What CO₂ sensor technology is used, and how often does it require calibration?
It uses a factory-calibrated, dual-beam infrared (IR) sensor. Annual verification against a NIST-traceable reference gas is recommended; field recalibration is not user-serviceable.
Is the incubator suitable for GMP environments?
Yes—when deployed with documented IQ/OQ/PQ protocols, alarm logs, and RS-485 data capture, it supports compliance with EU Annex 1 and FDA guidance for aseptic processing.
Can the inner chamber be sterilized using hydrogen peroxide vapor (HPV)?
The stainless-steel chamber and glass door are HPV-compatible; however, the UV lamp, sensors, and control electronics must be shielded or removed prior to decontamination cycles.
What is the warranty coverage and service support structure?
CZGY provides a 24-month limited warranty covering parts and labor. Technical documentation, firmware updates, and remote diagnostic support are available through authorized regional distributors.
