本文介绍一种半自动吸样器,适用大批各种体积的吸样工作,在吸样中是自动控制的,消耗駱源有限,装置简单而且快速,安全,特别适宜大批样品的吸取,在无自来水或电源的野外实验室,更显其优越性,各行业,科研单位的化验工作都可采用。一、原理:在一个装满自来水的密封的下口瓶中,其瓶口与诸吸管彼此联通(见图),控制下口瓶排水管的高度,并打开排水管,由于排水管与吸液管,处在相同大气压条件下,因而存在一个不平衡的 This article describes a semi-automatic sample applicator that is suitable for a large number of sample aspirations. It is automatically controlled during sample aspiration. It is limited in consumption of Luoyuan, simple and fast, safe, and especially suitable for the absorption of large quantities of samples without tap water. Or the power of the field laboratory, even more superiority, all industries, scientific research units can be used for laboratory tests. First, the principle: In a sealed bottom bottle filled with tap water, the bottle mouth and the straws connected to each other (see figure), control the height of the lower mouth of the bottle drain, and open the drain, due to the drain pipe and aspiration The tube is under the same atmospheric pressure and there is an imbalance
