Abstract
A testing device allows field tests to determine the presence of microorganisms in a given fluid. A container may have a culture medium in dry form, and a floatable device in the container. When a liquid sample is placed into a container, the floatable device floats on the surface and intercedes the exchange of oxygen from the atmosphere to the liquid. An oxygen content sufficient for aerobes is provided at the surface of the liquid, a reduced oxygen content for microaerobes provided just below the intercedent device, and no-oxygen content for anaerobes is provided at the bottom of the container. Selection of the culture medium can assist in detecting specific organisms, and further information can be gained by observing colorations, gas bubbles, precipitates and the like.
