The new generation of carbon dioxide incubators, based on the company's more than ten years of design and manufacturing experience, has always been guided by user needs, and constantly researches and develops new technologies and applies them to products. It represents the development trend of carbon dioxide incubators. It has a number of design patents and adopts imported infrared CO2 sensor to make the control accuracy accurate and stable without being affected by temperature and humidity. It has the function of automatic zero adjustment of CO2 concentration and automatic control of circulating fan speed to avoid excessive air flow during the test. This will cause the sample to evaporate, and an ultraviolet germicidal lamp is installed inside the box to regularly disinfect the box with ultraviolet rays, thereby more effectively preventing contamination during cell culture. Features: 1. Faster recovery speed of CO2 concentration The perfect combination of high-precision infrared CO2 sensor and microcomputer controller realizes the function of rapid recovery of CO2 concentration to the set state. Recover the set CO2 concentration to 5% within 5 minutes of potassium. Even when multiple people share a CO2 incubator and frequently open and close the door, the CO2 concentration in the box can be kept stable and uniform. 2. UV sterilization system The ultraviolet germicidal lamp is located on the back wall of the box, which can disinfect the inside of the box regularly, which can effectively kill the circulating air and the floating bacteria in the humidifying pan water vapor in the box, thereby effectively preventing pollution during cell culture. 3. Microbial high efficiency filter The CO2 air inlet is equipped with a high-efficiency microbial filter. The filtration efficiency is as high as 99.99% for particles with a diameter greater than or equal to 0.3 um, effectively filtering bacteria and dust particles in the CO2 gas. 4. Door temperature heating system The door of the CO2 incubator can heat the inner glass door, which can effectively prevent condensation water from the glass door and prevent the possibility of microbial contamination caused by the condensation water of the glass door. 5. Automatic control of circulating fan speed The speed of the circulating fan is automatically controlled to avoid sample volatilization due to excessive air volume during the test. 6. Humanized design It can be stacked (two floors) to make full use of the laboratory space. The large LCD screen above the outer door can display temperature, CO2 concentration value, and relative humidity value. Menu-type operation interface is easy to understand and easy to observe and use. . 7. Safety function 1) Independent temperature limit alarm system, sound and light alarm to remind the operator to ensure the safe operation of the experiment without accidents (optional) 2) Low or high temperature and over temperature alarm 3) The CO2 concentration is too high or high or low alarm 4) Alarm when the door is opened for too long 5) Working status of UV sterilization 8. Data recording and fault diagnosis display All data can be downloaded to the computer through the RS485 port and saved. When a fault occurs, the data can be retrieved and diagnosed from the computer in time. 9. Microcomputer controller: The large-screen LCD display adopts microcomputer PID control and can simultaneously display temperature, CO2 concentration, relative humidity and operation, fault prompts, and easy-to-understand menu operation for easy observation and use. 10. Wireless communication alarm system: If the equipment user is not on site, when the equipment fails, the system collects the fault signal in time and sends it to the mobile phone of the designated recipient via SMS to ensure that the fault is eliminated in time and the test is resumed to avoid accidental losses.
