More Information
Summary:A filter assembly is provided for collecting samples in a fluid environment, the assembly utilizing a laminar convective flow to cause the flow of a preservative/fixative and a filtrate through a filter. A substantially concave dead space around the filter is flushed free of the preservative and the differential in density of the preservative and filtrate causes the more dense fluid to collect in the reservoir and preserve the collected specimen. La présente invention se rapporte à un ensemble filtre permettant de collecter des échantillons dans un environnement fluidique, l'ensemble utilisant un écoulement convectif laminaire pour créer l'écoulement d'un conservateur/fixateur et d'un filtrat à travers un filtre. On rince sans conservateur un espace perdu sensiblement concave autour du filtre et le différentiel de densité entre le conservateur et le filtrat provoque la collecte d'un fluide plus dense dans le réservoir et la conservation de l'échantillon collecté.
