An assembly device and method for collecting and testing fluid samples more specifically for preparing and stabilizing nucleic acid components in a closed system. The assembly comprises a sample collection container with preloaded testing reagents and a safety separator to contain the testing reagents during sample collection. A fluid sample is delivered to the container and the assembly is subjected to centrifugation whereby the centrifugal load causes the separator to deform so that the separator migrates through the test reagents mixing the sample and reagents, and comes to rest atop the solids at the bottom of the tube.

1. A closed system for collection and testing of a sample, comprising an assembly, comprising:a container having an open end, a closed end, a side wall extending therebetween and an inner surface of the side wall; a resealable container closure; test reagent preloaded in the container wherein the test reagent is a buffered lysing solution for preparing and stablizing nucleic acid; and a deformable inert barrier in physical contact with the inner surface, between the reagent and the closure, and spaced from the closure to define a sample collection portion of the container therebetween; the inert barrier separating the reagent from with the sample collection portion, for safe sample collection, said barrier being deformable under centrifugal forces to permit passage of test reagent into the sample collection portion so as to mix the sample and the preloaded test reagent.
