Abstract
A device is adapted for containing a volume of growth medium and employed for detection of gas produced by a microorganism or microorganisms putatively contained within a test sample and added to the growth medium, comprising a primary chamber, a dome defined by the top surface of the primary chamber and communicating therewith, the dome establishing a fluid level and adapted for collection of gas produced by a microorganism within the growth medium, and a fill section adjacent to and communicating with one end of the primary chamber, the fill section spaced apart from the dome and extending above the fluid level, and further defining an opening for the addition of a test sample. The device may be sealed by means of a removable closure. An apparatus also consists of an array of substantially identical devices is also disclosed. In addition, methods of using the device and apparatus for detecting and estimating numbers of microorganisms, and for analyzing samples putatively containing a microorganism, are described.
