There are a variety of devices that include a culture medium to test for the presence of microorganisms. For example, a dip slide includes a culture medium that can be dipped into a liquid. Microorganisms, if present in the liquid, transfer from the liquid to the culture medium, which can then be incubated. In addition, an agar plate is often used to culture microorganisms. An agar plate is typically a round Petri dish that contains culture medium. An inoculator may be used to transfer the sample to be tested to the culture medium in the agar plate.
