The invention provides a CO2 concentration control device and method for a dry heat sterilization CO2 incubator. The device comprises an incubator, and a CO2 gas supply interface, a CO2 gas outlet interface, a CO2 gas return interface and a controller which are arranged on the incubator body, the CO2 gas supply interface is connected with a CO2 gas supply solenoid valve, the CO2 gas outlet interface is connected with an inlet of a CO2 concentration detection box through a CO2 gas outlet solenoid valve, an outlet of the CO2 concentration detection box is connected with the CO2 gas return interface through a CO2 gas return solenoid valve, and the CO2 gas return interface is connected with the controller. The CO2 gas supply electromagnetic valve, the CO2 gas outlet electromagnetic valve, the CO2 gas return electromagnetic valve and the CO2 concentration detection box are all connected with the controller, the CO2 concentration detection cabin used for detecting the CO2 concentration in the incubator is embedded in the CO2 concentration detection box and transmits concentration information to the controller, the controller controls the opening and closing duration of the CO2 gas supply electromagnetic valve, and the CO2 concentration detection cabin is used for detecting the CO2 concentration in the incubator. Therefore, the concentration of CO2 in the incubator can be accurately controlled. The CO2 concentration sensor does not need to be disassembled during high-temperature sterilization, and it can be guaranteed that the CO2 concentration sensor is not damaged by high temperature.
Description
technical field [0001] The invention relates to the technical field of cell modulation, in particular to a dry heat sterilization CO 2 CO in the incubator 2 Concentration control device and method. Background technique [0002] CO 2 The incubator is an advanced instrument for cell, tissue, and bacterial culture. It is the key equipment necessary for immunology, oncology, genetics and bioengineering. 2 The incubator is improved on the basis of the ordinary incubator, mainly by adding CO. 2 , to meet the environment required for culturing microorganisms. CO in the incubator 2 The main role is to adjust the pH of the cell culture medium, it is the use of stable CO 2 The concentration of sodium bicarbonate is in equilibrium with the sodium bicarbonate of the medium, so as to achieve a relatively stable pH value, which is conducive to the growth of cells. CO 2 Too high or too low concentration is not conducive to the adjustment of pH value, and also affects the growth of ...
