More elaborate incubators can also include the ability to lower the temperature (via refrigeration), or the ability to control humidity or CO 2 levels. This is important in the cultivation of mammalian cells, where the relative humidity is typically >80% to prevent evaporation and a slightly acidic pH is achieved by maintaining a CO 2 level of 5%.
An incubator is a device simulating avian incubation by keeping eggs warm at a particular temperature range and in the correct humidity with a turning mechanism to hatch them. The common names of the incubator in other terms include breeding / hatching machines or hatchers , setters , and egg breeding / equipment .
The humidity is also critical, because if the air is too dry the egg will lose too much water to the atmosphere, which can make hatching difficult or impossible. As incubation proceeds, an egg will normally become lighter, and the air space within the egg will normally become larger, owing to evaporation from the egg.
The specific advancements made by Ramsey and Boone's 1972 paper were further developing incubators with features aimed at controlling temperature, atmosphere, humidity, and reducing bacterial exposure. Construction was made with plywood and 2.5 cm polystyrene insulation, and plexiglass and glass viewing ports for visibility.
They need to be kept at body temperature (37 °C) in an incubator. [1] These conditions vary for each cell type, but generally consist of a suitable vessel with a substrate or rich medium that supplies the essential nutrients ( amino acids , carbohydrates , vitamins , minerals ), growth factors , hormones , and gases ( CO 2 , O 2 ), and ...
