Abstract

Procedimiento y dispositivo para depositar en un recipiente una dosis predeterminada de una sustancia líquida, consistiendo el procedimiento en primer lugar en efectuar una toma de esta sustancia en una pieza tubular dispuesta verticalmente por encima del recipiente, caracterizándose el procedimiento porque a continuación se enfría una parte inferior de la pieza tubular, siendo esta parte inferior un tubo calibrado, se aplica una presión vertical dirigida hacia abajo sobre el nivel superior de la sustancia extraída en la pieza tubular, siendo suficientemente intenso este enfriamiento para que, bajo la influencia de la presión, se forma un cordón continuo vertical de sustancia congelada bajo el tubo calibrado, y se corta el cordón de modo que un fragmento de longitud predeterminada desunido del cordón sea recibido por gravedad en el recipiente, constituyendo este fragmento, tras la licuación, la dosis predeterminada.
