Three-Gas Incubator CN-SQ80B with Precise Gas Concentration ControlOur core technological advantage lies in its exceptional ability to precisely control gas concentrations. By integrating highly sensitive oxygen and carbon dioxide sensors, combined with advanced proportional valves and a microprocessor control system, the equipment can continuously monitor and dynamically adjust the three gases—O₂, CO₂, and N₂—within the culture chamber in real-time. This closed-loop feedback control system ensures a quick and stable recovery to the user-defined precise gas environment even after door disturbances, providing unprecedented environmental stability and reliability for cell experiments. It is particularly suitable for stem cell culture, tumor hypoxia research, or neural cell experiments that are extremely sensitive to fluctuations in gas concentrations.

Precise gas control capabilities directly determine the scientific value and reproducibility of high-end cellular experiments. The CN-SQ80B can stably create and maintain a wide range of oxygen concentrations, from extremely low (such as 1% O₂ simulating in vivo microenvironments) to high, while precisely mixing CO₂ to maintain a stable pH in the culture medium. This capability allows researchers to accurately simulate gas conditions under physiological or pathological states, deeply studying the regulatory effects of oxygen concentration on cell proliferation, differentiation, metabolism, signaling pathways, and gene expression. This enables more physiologically realistic experimental data in fields such as regenerative medicine, cancer biology, and drug screening, driving breakthroughs in basic research and translational applications.

In addition to the core gas control system, the CN-SQ80B typically comes equipped with a series of auxiliary designs to ensure the actual effectiveness of control precision. For instance, the optimized cavity air circulation design ensures uniformity in temperature, humidity, and gas concentration, avoiding local microenvironment discrepancies; high-quality door seals and sealing materials minimize gas leakage to the maximum extent; and the intuitive touchscreen interface allows users to easily set complex multi-step gas concentration programs. These features collectively create a highly controllable, uniform, and user-friendly cell culture platform, making it a key piece of equipment for modern biological research labs conducting cutting-edge cell research and ensuring the accuracy and consistency of experimental results.

CN-SQ80B Triple Gas Incubator - Precise Gas Concentration ControlKey Features:

1. The CO2 gas concentration detection uses an IR infrared sensor to calculate the CO2 gas concentration. During operation, the sensor has no mechanical wear, rapid response speed, high reliability, good stability, and a long service life.

2. The CO2 gas concentration detection utilizes imported electrochemical oxygen sensors, featuring good linearity, high accuracy, and a long lifespan, fully meeting the user's requirements.

3. All temperature detection uses imported PT100 resistance temperature sensors, offering stable performance and good linearity.

4. When the O2 concentration is less than 19.8%, high-purity N2 and CO2 gases are used to ensure the accuracy of the CO2 and O2 concentrations.

When the O2 concentration exceeds 23%, use high-purity O2 and CO2 gases to ensure the accuracy of the CO2 and O2 concentrations.

6. The interior utilizes a gentle air circulation method, approximating natural air convection for optimal air circulation. This reduces the recovery time for temperature, humidity, O2, and CO2 concentration, ensuring balanced levels of all these factors.

7. When the box door is open, the solenoid valve automatically closes, stopping the micro-ventilation. This reduces gas loss and conserves resources, as well as minimizing contamination from external air entering the box.

8. Temperature and gas concentrations are both displayed digitally for clear, precise, and intuitive viewing.

9. Equipped with multiple protection features, it can automatically shut off all heating power when the display temperature exceeds the preset temperature. It also features an independent over-temperature relay protection to ensure the temperature does not exceed the preset value.

10. Natural evaporation humidifier with a water pan, achieving 95% humidity. Made of 304 stainless steel, curved design for easy cleaning.

11. Sterilization System: UV light sterilization, flexible and controllable, with short operation time. It also allows for selection of high-temperature moist heat sterilization or high-temperature dry heat sterilization based on experimental requirements.
