New CO2 Incubator White Paper: Antimicrobial Testing on Copper versus Copper Alloys

Laboratory incubators are devices used to grow and maintain microbiological cell cultures. CO2 incubators work in such a way that it controls three important factors for cell growth: temperature, relative humidity, and carbon dioxide level. It is important to avoid microbial contamination and maintain the purity of these cell cultures in order to obtain accurate test results.

 

Copper and its alloys have been known to have antimicrobial properties since the dawn of civilization, although the molecular mechanisms by which they work are still under investigation.

 

In line with this, the microbiologists of Esco did a study on the antimicrobial effectiveness of pure copper and its alloys on six different organisms, namely: Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Staphylococcus epidermidis, Candida albicans, and Bacillus atrophaeus.

 

The test results indicate significant reduction of cells upon contact with copper and its alloys. It was found out that pure copper is the most effective antimicrobial surface. In fact, it can kill all cells (E. coli, S. aureus, P. aeruginosa, and S. epidermidis) in just one hour, although it took a longer time for the C. albicans and B. atrophaeus cells to be reduced. It was also found out that copper alloy C19210 is the most effective against microorganisms, having the most copper content compared to the other alloys.

 

Thus, the Esco’s CelCulture CO2 incubator with its 100% Copper interior chamber is sure to provide your cells with added protection.
