Bureta para Gas a Alta Presi\u00f3n – \u00a0Serie 2280<\/figcaption><\/figure>\n

Parr ofrece una serie de buretas de alta presi\u00f3n<\/strong> para introducir gas (com\u00fanmente hidr\u00f3geno) en un reactor a una presi\u00f3n constante. Las buretas consisten en un dep\u00f3sito a alta presi\u00f3n equipado con una v\u00e1lvula de entrada, un man\u00f3metro y una v\u00e1lvula de alivio. Un regulador de presi\u00f3n constante con una v\u00e1lvula de retenci\u00f3n, una manguera de conexi\u00f3n y un base de soporte se incluyen con cada pipeta. La cantidad de gas consumido en una reacci\u00f3n puede ser determinada si se conoce el volumen del dep\u00f3sito a alta presi\u00f3n y se observa la ca\u00edda de presi\u00f3n en el dep\u00f3sito durante la reacci\u00f3n. Las buretas de alta presi\u00f3n Parr pueden suministrarse en varios tama\u00f1os, como se muestra en la siguiente tabla, cada una con un regulador para entregar gas al reactor durante el rango de presi\u00f3n designado. Los moles de gas mostrados en la tabla representan la cantidad de hidr\u00f3geno que se mantendr\u00e1 en la bureta a la presi\u00f3n m\u00e1xima. El volumen de entrega ser\u00e1 una funci\u00f3n de la diferencia de presi\u00f3n entre la pipeta y el reactor. El tama\u00f1o de la bureta debe ser seleccionado lo suficientemente grande como para proporcionar gas suficiente para completar la reacci\u00f3n mientras se mantiene presi\u00f3n suficiente en la bureta para forzar el gas hacia al reactor.<\/p>\n

Dep\u00f3sitos de vol\u00famenes mayores est\u00e1n disponibles,<\/strong>as\u00ed como reguladores con diferentes rangos de entrega. Se pueden hacer modificaciones a estos sistemas b\u00e1sicos para agregar un termopar interno al dep\u00f3sito y\/o un transductor de presi\u00f3n para la lectura digital y\/o grabaci\u00f3n.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n
