CO2 Disc Test

 The Pulse Scientific CO2 Disc Test is a chemical indicator system designed to provide visible indication of achieving a 5% carbon dioxide environment.

 

The growth of many disease-producing microorganisms is either enhanced or dependent on a carbon dioxide environment. The most commonly used environment is a 5% concentration of carbon dioxide. Numerous devices and systems have been developed and proposed for generating an optimum carbon dioxide environment. It is necessary to determine if an optimum environment has been achieved and maintained in specific transport devices and during incubation. The Pulse Scientific CO2 Disc Test provides a visible indication that a 5% carbon dioxide environment has been achieved and maintained.

 

The Pulse Scientific CO2 Disc Test consists of a chemical complex and carrier device. The presence of molecular carbon dioxide forms carbonic acid in the carrier device. When the concentration of carbonic acid exceeds the buffering capacity of the chemical complex, a color change from pink to colorless indicates that a 5% carbon dioxide environment has been achieved. A decrease or termination of a 5% carbon dioxide environment will result in a change from colorless back to the original pink color.
