Abstract

L'invention concerne un récipient obturé en permanence pour maintenir un échantillon fluide. Selon l'invention, il comprend une partie cylindrique centrale 12 de forme uniforme, un fond hémisphérique fermé 14 faisant corps avec la partie centrale, et un sommet hémisphérique et généralement fermé 16 faisant corps avec la partie centrale, le sommet ayant un orifice de remplissage 20 sensiblement plus petit que la largeur de la partie centrale, l'orifice 20 étant obturé en permanence pour établir un récipient hermétiquement obture de façon que l'échantillon fluide occupe sensiblement tout le volume interne du récipient et ne contacte aucun autre matériau à l'exception de celui dont le récipient est fait, afin que l'échantillon fluide ne puisse être contaminé. L'invention s'applique notamment au récipient à placer dans un rotor de centrifugeuse.
