Dehydrated culture media

Supplier: Merck

Description: Dehydrated media are used for a wide variety of applications. To minimise the risks associated with powdered culture media, the majority of Merck's dehydrated culture media is produced in granular form. Merck uses ingredients of non animal origin to minimise the potential risk of transmissible spongiform encephalitis (TSE). When there is no alternative, only ingredients which are recommended by EDQM, and belonging to TSE category B or C are used. This ensures that the product is of the highest quality and in compliance with the standards for food control, microbiological testing on finished products and starting materials, and quality control in the pharmaceuticals and cosmetics industries. Custom-made media can be prepared to meet individual customer specifications. The formulation is kept confidential via a Non Disclosure Agreement. Please enquire for further details.
