Dr A. Rambach, founder of CHROMagar™, developed the use of this technology in food microbiology. The main advantage of using chromogenic media is the ability to distinguish with the naked eye different microorganisms growing on the same plate.


All CHROMagar™ products are dehydrated culture media. The unit size of every packs is indicated in volume (litres or millilitres) that shows the volume of culture medium that you can prepare: With one bottle you can prepare 5 or 25 L of culture media.


After the preparation of the medium starting from the powder, the 5 L pack allows you to prepare around 250 plates, while the 25 L allows you to prepare 1250 plates.


Every chromogen exhibits its own distinctive colour; the result is a very specific and distinctive colouring of different microorganisms which become clearly distinguishable to the naked eye under normal lighting conditions.


The 'Rambach Agar', available in this product range, is still one of the most used and famous chromogenic culture media for detection and isolation of Salmonella spp.


Delivery information: Supplements always included in the pack.


Packaging: 5 L pack = dehydrated culture media to prepare 5 L of agar or broth or 25 L pack = dehydrated culture media to prepare 25 L of agar or broth.
