Microbiological systems for the automation of a microbiological laboratory including apparatus and methods for dilution of a microbiological sample, distribution of the sample to utilization devices, and application of the microbiological sample onto a growth medium in a sterile condition. In one embodiment, a fluid amplifier device is utilized for dilution of the microbiological sample and a fluid amplifier is also utilized for distribution of the diluted sample to a receiving well. In another embodiment, the microbiological sample is linearly applied to an elongated petri dish for subsequent incubation. Appropriate elongated petri dishes are described for use with such linear applications. A piston-cylinder arrangement is also provided for serial dilution of the samples.
