Abstract

La présente invention porte sur une tête d'échantillonnage, comprenant un capillaire (1), le capillaire (1) composé d'un corps (1-4) de tube à diamètre interne réglable, une admission (1-2) de liquide étant disposée au niveau d'une extrémité du corps (1-4) de tube à diamètre interne réglable, et la sortie (1-1) de liquide étant disposée au niveau de l'autre extrémité du corps (1-4) de tube à diamètre interne réglable, et le rapport du diamètre interne de la sortie (1-1) de liquide du capillaire (1) et le diamètre interne de l'admission (1-2) de liquide étant de 0,3-0,8:1 ; ou le capillaire (1) est composé d'un corps (1-3) de tube à diamètre interne égal et d'un corps (1-4) de tube à diamètre interne réglable communiquant l'un avec l'autre, une admission (1-2) de liquide étant disposée au niveau d'une extrémité du corps (1-3) de tube à diamètre interne égal, et une sortie (1-2) de liquide étant disposée au niveau d'une extrémité du corps (1-4) de tube à diamètre interne réglable, et le rapport du diamètre interne de la sortie (1-1) de liquide du capillaire (1) et le diamètre interne de l'admission (1-2) de liquide étant de 0,3-0,8:1. La tête d'échantillonnage est appropriée pour échantillonnage quantitatif dans le domaine biologique, chimique et médicale et présente l'avantage d'être aisée à utiliser et d'accroître significativement le taux d'échantillonnage.
