CO2 Incubators: Air or Water Jacket?

CO2 incubators, which are equipment that differ from common-use incubators fundamentally in that they provide an atmosphere in which the percentage of CO2 present, temperature and relative humidity are controlled.

How is a CO2 incubator made?

A CO2 incubator is mainly composed of a chamber that contains openings for the entry of air, CO2 and for taking samples, in which the fundamental process for which the equipment is intended is carried out; such as incubation and growth of cells and tissues.

In addition, they have a control panel or block that allows the selection of the different functions, among which are the settings of incubation temperature, CO2 concentration, relative humidity, if present, startup times. , incubation and stop, as well as the respective alarm values.

The incubation chamber is surrounded by a shirt or jacket which, depending on the type of incubators, can be filled with water or air and a heating element that will be attached to the outer walls of the incubation chamber. It is also necessary for the jacket to be separated from the outside by thermal insulation to minimize the interaction of the ambient temperature with that of the incubator. An important part is the power elements (electrical resistances) that are responsible for supplying energy to keep the temperature constant.

Types of CO2 incubators

There are different types of CO2 incubators, such as:

  • Air jacket and direct heat.
  • Water jacket.

Air jacket incubators are easier to set up and reach the set temperature much faster than water jacket incubators, they also have the advantage of weighing much less, allowing them to be easier to transport.

The water jacket incubator takes longer to start up, requiring filling, emptying and cleaning of the water tank, as well as monitoring the operation of the water tank.
