Cell culture technology refers to the technology of cultivating and researching living cells by selecting the best living conditions of various cells, and is an important technology widely used in the field of life sciences. The CO2 shaking incubator mainly cultivates biological cells by simulating the temperature, humidity, PH value of organisms, etc. It is an indispensable incubator for cell culture in the laboratory. Generally, the pH of the cell culture fluid is between 7.0-7.4. Since the carbonate pH buffer system is a physiological pH buffer system (it is the most important pH buffer system in human blood), most culture fluids use it to maintain a stable pH. When formulating culture medium with powder, it is often necessary to add a certain amount of sodium bicarbonate. For most culture fluids that use carbonate as a pH buffer system, in order to maintain a stable pH, the CO2 in the incubator needs to be maintained between 2-10% to maintain the concentration of dissolved CO2 in the culture fluid. At the same time, cell culture vessels need ventilation to facilitate gas exchange. Does the use of other pH buffer systems eliminate the need for a CO2 shaking incubator? It is found that due to the low concentration of CO2 in the air, if the cells are not cultured in a CO2 incubator, the HCO3- in the culture medium will be depleted, which will affect the normal growth of the cells. Therefore, the cultivation of most animal cells still requires a CO2 shaking incubator.
The role of CO2 shaking incubator:
1. The CO2 shaking incubator can provide the most accurate and stable control of temperature, CO2 concentration and humidity, in order to facilitate the progress of its research work.
2. The CO2 shaking incubator can effectively prevent microbial contamination in the incubator, and can eliminate pollution regularly to protect research results and prevent sample loss.
3. CO2 shaking incubator is widely used in the cultivation of cells, tissue culture and some special microorganisms, commonly used in cell dynamics research, collection of mammalian cell secretions, carcinogenic or toxicological effects of various physical and chemical factors, antigens Research and production, cultivation of hybridoma cells to produce antibodies, in vitro fertilization (IVF), stem cells, tissue engineering, drug screening and other research fields.
4. CO2 shaking incubator is an advanced instrument for cell, tissue and bacteria culture. It is also a key equipment necessary for the development of immunology, oncology, genetics and biological engineering. It is widely used in the research and production of microorganisms, agricultural sciences, and medical experiments.
