Abstract

La présente invention concerne des rotors à force centrifuge servant à amener un volume prémesuré de liquide dans une chambre de rotor. En particulier, lesdits rotors comprennent des siphons (134) servant à amener un volume prémesuré de liquide entre une première et une seconde chambre (136) du rotor. Les siphons (134) selon l'invention sont conçus de sorte que l'entrée (138) du siphon de la première chambre se trouve radialement à l'extérieur de la sortie (139) du siphon de la seconde chambre (136). La première chambre est vidée jusqu'à un niveau correspondant à la position radiale de la sortie (139) du siphon.
