The Delvotest Accelerator is an automated system in which the plates containing the milk to be analyzed are placed for incubation.
This reduces growth and acid production by the test organism, and delays or prevents the agar from changing color from purple to yellow. The principle of the test is based on the diffusion of possible inhibitory substances that may be present in the milk sample into agar.
The milk sample is added onto the agar gel, and the test is incubated at 64 degrees C.
The test is made of an agar gel containing bacterial spores and a color indicator. Delvotest SP NT DA is designed to test milk for the presence of antibacterial substances, such as antibiotics.
