Medium Description

Gain flexibility using powder rather than ready to use plates: Use the entire pack, or if there is a need for a smaller number of plates, just a portion. If kept under appropriate storage temperature, CHROMagarTM Enterobacteria has a 2 years shelf of life. This flexibility is essential to avoid the waste resulting from expired-unused plates. 

Please refer to our IFU and Material Safety data sheet for complete information about the medium. CHROMagar™, Rambach™, AquaCHROM™ are trademarks created by Dr. A. Rambach.
