CO2 is important for maintaining constant pH in cell culture. Unfortunately, I do not have access to such incubator and buying a new one is expensive. I found a cheap incubator online, but it doesn't support CO2. I'd like to ask if I can cultivate cheek epithelial cells in such incubator and if it won't negatively affect my cell culture. Another option is building a small CO2 generator inside the incubator. I made some calculations - I know how much CO2 I need to generate, how many grams and mL of solutions I need, moreover the build-up pressure is so small, it should not negatively affect the incubator.

    $\begingroup$ Are you familiar with CO2-independent growth media? (I don't know anything about culture of that cell population specifically, though) $\endgroup$ – Bryan Krause Feb 27 '20 at 18:06
  • $\begingroup$ Thank you very much. I am not familiar with CO2-independent growth media, but I will take a look. I planned to buy a cheap DMEM from eBay. I hope, there are some inexpensive media you mentioned, or at least a method to convert DMEM to such medium. $\endgroup$ – Incorrect syntax near Feb 27 '20 at 19:34

L-15 media does not require a CO2 atmosphere and according to Sigma-Aldrich this media is suitable for primary explants of adult human tissues.

Without that support, your answer is indistinguishable from opinion. This is a good example of how to format references. Thank you! 😊 $\endgroup$ – tyersome Feb 27 '20 at 23:38
