Abstract

La presente invencción se refiere a un dispositivo que funciona para la separación de la fracción más ligera a partir de la fracción más pesada de una muestra líquida, para utilizarse con dos receptáculos rígidos evacuados, en donde cada receptáculo incluye un extremo abierto y un tapón perforable que cierra en forma sellable el extremo abierto; que comprende: un alojamiento que tiene una cavidad interior; una membrana separadora que divide la cavidad en una primera porción y una segunda porción, teniendo la membrana separadora una porosidad seleccionada para la separación deseada, a través de la misma; un medio de entrada para proporcionar comunicación de fluido entre la primera porción y la fuente de la muestra líquida; un primer medio de comunicación para proporcionar comunicación de fluido entre la primera porción y un primer receptáculo evacuado, estando el primer medio de comunicación colocado en relación opuesta desde el medio de entrada, de modo que el líquido que pasa desde el medio de entrada hacia el primer medio de comunicación viaje en una dirección a lo largo de la superficie de la membrana; un segundo medio de comunicación para proporcionar comunicación de fluido entre la segunda porción y un segundo receptáculo evacuado de modo que, cuando el medio de entrada esté en comunicación de fluido con la fuente de la muestra líquida y el primer medio de comunicación esté en comunicación de fluido con el primer receptáculo evacuado y el segundo medio de comunicación esté en comunicación de fluido con el segundo receptáculo evacudo, la muestra líquida fluya a través del medio de entrada, a lo largo de la membrana, a través del primer medio de comunicación, hacia el primer receptáculo evacuado, simultáneamente, atrayéndose la fracción más ligera del líquido a través de la membrana y el segundo medio de comunicación, hasta el receptáculo evacuado; y un medio de sujeción para sujetar el primer receptáculo evacuado y el segundo receptáculo evacuado, en una relación fija uno con respecto al otro; y medios de cordinación entre el alojamiento y el medio de sujección, para facilitar el movimiento controlado de los receptáculos evacuados hacia acoplamiento y comunicación de fluido con el primero y segundo medios de comunicación.
