    • PROBLEM TO BE SOLVED: To provide a dispensing nozzle and an automatic analyzer that have a simple constitution, and allow accurate dispensation of a liquid sample whose viscosity extends over a wide range. SOLUTION: This dispensing nozzle 11 and automatic analysis apparatus have a holding cylinder section 11a for holding discharge object liquid and a discharge end surface 11b, that is formed at the tip of the holding cylinder section, sucks the liquid, and forms a delivery opening 11c. The discharge end surface 11b of the dispensing nozzle 11 has a contact angle with the liquid larger than that of the inner surface of the holding cylinder section 11a. The boundary, between the inner surface of the holding cylinder section 11a and the delivery end surface 11b, has a different contact angle with the liquid. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:提供一种具有简单结构的分配喷嘴和自动分析器,并且允许其粘度在宽范围内延伸的液体样品的精确分配。 解决方案:该分配喷嘴11和自动分析装置具有用于保持排出物体的保持筒部11a和形成在保持筒部的前端的排出端面11b吸引液体,形成 输送开口11c。 分配喷嘴11的排出端面11b与液体的接触角大于保持筒部11a的内表面的接触角。 在保持筒部11a的内表面和输送端面11b之间的边界与液体的接触角不同。 版权所有(C)2009,JPO&INPIT
