Abstract
A centrifuge tube and a kit for detecting the presence or absence of microorganisms, particularly bacteria and yeasts, in a liquid sample of a biological material. The centrifuge tube has a cylinder portion; a frustoconical portion; a capillary at the bottom of the tube; and contains a gel system for detecting microorganisms. The gel system includes a development phase of a gel containing microorganism culture medium and a reagent capable of inducing a detectable variation in optical measurement in the presence of microorganisms and a first phase intimate mixture which includes water originating wholly or partly from the culture medium and water-absorbing polymer particles so that, in the first phase intimate mixture, the polymer particles have a particular concentration and size.
