ABSTRACT:
An apparatus for mixing fluids especially suitable for use in laboratory tests for the detection of microbial pathogens which includes an elongated centrifugation vessel, an injectable closure, completely enclosing a treating fluid chamber, and a novel stylus which causes a sample to be admixed and commingled with a treating fluid upon injection. The treating fluid is disposed within the treating fluid chamber and a sterile aqueous solution having a greater density than a sample fluid but able to selectively receive microbial pathogens from the sample fluid is disposed within an evacuated space within the centrifugation vessel. The sample is mixed with the treating fluid when the novel stylus is injected through the injectable closure means facilitating contact of the treating fluid and the sample via an aperture or apertures longitudinally spaced along the stylus so as to be within the treating fluid chamber upon injection of the stylus. The sample-treating fluid mixture then continues its flow through the canalis of the stylus and is deposited on the aqueous solution within the evacuated space of the centrifugation vessel.
