背景技术 Background technique

化学实验中所用的药品绝大多数是液体状态,而其中绝大多数具有毒性和难闻的气味,在实验中用的液体药品大多是从试剂瓶中倒取的,从试剂瓶中倒取液体试剂时经常会倒洒、倒多,不容易控制,既浪费药品又导致药品的气味充斥实验室,另外,撒在瓶口外边的药品还会粘在再取药品人手上,有害健康。 The vast majority of medicines used in chemical experiments are in liquid state, and most of them have toxicity and unpleasant smell. Most of the liquid medicines used in experiments are poured from reagent bottles, and the liquids from reagent bottles Reagents are often spilled and poured too much, which is not easy to control, which not only wastes medicines but also causes the smell of medicines to flood the laboratory. In addition, medicines sprinkled outside the bottle mouth will stick to the hands of people who take medicines again, which is harmful to health.

日常生活或工作中,需倒取一定量的液体,如药水、化学试剂等,为了取到需要量的液体,常常是用刻度瓶子倾倒或用带刻度的吸管取液,还有就是先将液体倒在量筒或量杯内,然后再使用。带来的缺点就是1.液体在量取过程中环节过多,易产生二次污染,2.倒出的液体量需边观察边倾倒量取,不能一次到位,过程较繁琐,并难以准确掌握,3.倒药时难免有少量试剂沿瓶口流下,不卫生也不方便。 In daily life or work, it is necessary to pour a certain amount of liquid, such as syrup, chemical reagents, etc., in order to get the required amount of liquid, it is often poured with a graduated bottle or taken with a graduated straw, and the liquid is first Pour into a graduated cylinder or cup before use. The disadvantages are 1. There are too many steps in the process of measuring the liquid, which is easy to cause secondary pollution. 2. The amount of poured liquid needs to be measured while observing, and it cannot be in place at one time. The process is cumbersome and difficult to accurately grasp , 3. When pouring the medicine, it is inevitable that a small amount of reagent will flow down the bottle mouth, which is unhygienic and inconvenient.
