Hardy Diagnostics was the first company to introduce chromogenic media to America in 1996. Over the years, Hardy has developed the largest line of chromogenic media in the US. Our formulas are unique and have been meticulously and painstakingly developed by our R&D microbiologists, who must test hundreds of formulas before confirming the optimal combination of ingredients for the final product. This resulted in a media that provides microbiologists with an effective and accurate tool to identify target organisms based on colony color formation, improving patient care and saving your lab time and money. Try out some samples of our chromogenic media in your testing program and discover the difference that HardyCHROM™ products can make.
