Abstract

Agar medium transport devices are utilized in bacteriological studies. One such device is shown. This device utilizes available space to a maximum by dividing the dish 1 into four circular compartments 2...5. The width and depth of each compartment, or media troughs, are determined by bacterial requirements consisting of nutrient need and colony size. Each trough is arranged to contain a different media. For example, the outside ring 2, which is longest, contains a media expected to support the largest number of microorganisms, while the shortest, innermost ring 5, contains the most selective media. A good material for this device is LEXAN* plastic, based on its optical properties, rigidity, ability to withstand autoclaving and nontoxicity to microorganisms. *Trademark of General Electric Co.
