CO2 incubators play an important role in the preparation of tests or experiments in all areas of cancer research, such as active agent research, 3D invasion development, assays and biosensors, from simple monolayer to reproduction of patient tumors using 3D cell culture models (drug research and therapy development). In the areas of immunology and tumor biology (development of malignant tumors), both CO2 incubators at 37ºC with a CO2 volume of 5% and 95% relative humidity are used for normoxic culture conditions as well as CO2 / incubators. O2 at 37ºC with a volume of CO2 of 5% and a volume of hypoxia of 1% of volume of O2, depending on the cell cultures.
