The Right Choice for CO2 Incubators

CO2 incubators are designed to copy a cell’s natural environment with a relative humidity of around 95 percent, a temperature of 37°C and a pH of 7.2 to 7.5. They are most common in biology labs performing tissue or cell culture and are used in any process where cells need to be cultured for a few hours or many weeks or where cells need to be expanded or maintained. Because incubator cleaning and operations must be validated in regulated work, CO2 incubators now offer very tight control over conditions within the instrument. When an incubator’s door is opened to remove or introduce samples, those conditions can quickly change, potentially damaging the viability or health of cells. However, many incubators on the market automatically begin re-equilibration of gas concentration and measure CO2 through infrared sensors to prevent such catastrophes. Cleaning is also extremely important in the maintenance of the incubator with heat or ultraviolet light being the traditional methods of disinfection. While effective, the downside of heat is that it is tough on the incubator’s materials of construction. And UV light, while also effective, sometimes leaves nooks and crannies contaminated as it works only on line of sight. Check with your vendor to learn which CO2 incubator is best for your lab.
