Supplements for Culture Media

Most selective media require special supplements or additives to ensure optimal performance for isolating and identifying specific microorganisms. If available in a freeze-dried format, preparation and handling becomes particularly easy.

Merck’s supplements are typically portioned to be added to a standard volume of 500 ml of culture media. Our wide range of additives, such as antibiotics, glycerol or Tergitol, provides additional flexibility.

Freeze-Dried Contents for Greater Safety and Ease-of-Use

To avoid any accidents upon opening, our supplements are provided with a user friendly screw cap and a separate rubber stopper closure. Due to the freeze-dried format of the content, no hazardous substances or aerosols are inhaled when opening. The freeze-dried pellet also goes into solution easily.

Granulated Media with Incorporated Selective Agents

Any additional step in the preparation of culture media, such as adding supplements or additives, is time consuming and a possible source of contamination. Where possible and sensible, heat stable additives have been incorporated into Merck’s dry granulated media.
