Abstract

La presente invención se refiere a un aparato para separar los constituyentes en una muestra líquida introducida en el aparato en aquellos que tienen una gravedad específica superior y aquellas que tienen una gravedad específica inferior, bajo la acción de fuerza centrífuga, caracterizado por; (a) un recipiente transparente de configuración de tubo, que tiene un extremo cerrado y un extremo abierto y que define una cámara receptora de muestra; (b) un tapón penetrable por aguja para cerrar el extremo abierto del recipiente; (c) un conjunto de barrera doble movible axialmente en el recipiente bajo la acción de fuerza centrífuga; (d) un conjunto de barrera doble que tiene una gravedad específica intermedia a la gravedad específica de los constituyentes de una muestra introducida hacia el recipiente, que tiene una gravedad específica superior y aquellos que tienen una gravedad específica inferior; (e) un conjunto de barrera doble que proporciona selectivamente un sello anular doble y pasaje abierto alrededor del mismo en respuesta diferenciales de presión en el recipiente, por encima y debajo del conjunto de barrera doble; (f) el conjunto de barrera doble comprendiendo; (1) una porción flexible de configuración de copa; (2) la porción flexible de configuración de copa teniendo un primer anillo anular adyacente al borde superior del mismo; (3) el borde circunferencial externo del primer anillo anular selectivamente movible hacia y fuera de acoplamiento de sello con la pared interna de la cámara de recipiente, en respuesta a presiones alternas iguales y diferentes por encima y debajo del conjunto doble; (4) cuando menos una abertura en la pared inferior de la porción flexible de configuración de copa que proporciona comunicación de fluído a través de la misma; (5) un núcleo sólido redondo encajado en la porción de configuración de copa; (6) un segundo anillo anular que se extiende desde la superficie externa de la porción de núcleo sólido; (7) la porción de núcleo sólido movible verticalmente en la porción de configuración de copa, para ocasionar que el primero y segundo anillos se muevan en y hacia fuera de acoplamiento de sello entre sí, en respuesta a presiones alternas iguales y diferentes por encima y por debajo del conjunto doble; y (8) un elemento para conectar la porción de núcleo sólido y la pared inferior de la porción de configuración de copa flexible.
