Carbon Dioxide Incubator

CO2 Incubators are devices that offer optimal conditions for the growth of microorganisms, and also other cell types. The CO2 incubator is commonly found in laboratories for pathology, in dairy products, in other industries as well as in research institutions. The CO2 incubators are equipped with HEPA filtration to keep a sterile and clean environment, and sensors which monitor the slightest changes in humidity, temperature and levels of oxygen and carbon dioxide. The more advanced CO2 incubators may include refrigeration for maintaining cell lines which require lower temperatures. You can get the best CO2 meter in this sites.


Basic problems of CO2 incubators include maintaining a sterilized atmosphere, preventing the dehydration and drying of cells, and controlling heat loss from frequent opening and closure of the incubator’s door. Modern incubators employ more advanced technology to avoid temperature fluctuations. These incubators can maintain the best conditions for growth.

Effective Temperature Management

In essence, there are two kinds of CO2 incubators: air jacketed or water jacketed. The air jacketed incubators use air as the cooling and heating medium. In general, water-sleeved incubators have smaller temperature variations than those with air sleeves. On the other hand air- jacketed incubators help reach optimal temperatures within very little time and minimize the effects of temperature variations.

Avoiding contamination

The metal surfaces, the copper linings and the fixtures prevent the growth of unwanted microbes in the incubator. This is true both for the exposed surfaces and the hidden crevices. Most CO2 incubators use hydrogen peroxide and UV sterilization systems. In order to avoid contamination, the HEPA filter can be increased. But this will tend to desiccate cells as they grow best when the relative humidity is 95%. The use of humidity sensors is a way to help combat this problem, but it still remains a concern among manufacturers and scientists.

Alarm and Backup System

These advanced models have sensors that can detect when a certain parameter is out of range. They then activate the backup system. These are best suited to more specific experiments. For example, tissue culture experiments are performed under very strict conditions.

The HCO3 created by the interaction of CO2 with water is a protective buffer that protects the cells. Infrared detectors are sometimes used in some CO2 incubators to measure fluctuations in carbon dioxide or oxygen levels. They are able to maintain the CO2 level at around 5%. This is the ideal concentration for the cells.
