The series CO2CELL is suitable for research and growth of cell and other cultures and it is also frequen NO₂. The operation of the CO2CELL incubators is based on the smooth gravitational flow of the operation gas in the electrically heated chamber with high relative humidity and selected gas concentration. The units operation is noiseless. As a standard, protective CO₂ atmosphere is used. According to the customer’s wishes, O₂ or NO₂ can also be applied.
