在化学分组实验准备工作中，配制好的溶液要分装到一个个小瓶中，工作起来非常麻烦，时刻要注意安全，有的还会因用漏斗、烧杯污染了溶液，造成实验效果不明显，甚至失败，于是我自制了“气压式溶液分装器”达到了在分装溶液过程中安全、防污、方便的目的。１材料及组装打气球 In the chemical grouping experiment preparation work, the prepared solution should be packed into one vial. It is very troublesome to work. It is necessary to pay attention to safety at all times, and some of the solutions are contaminated with funnels and beakers, resulting in inconspicuous results. Even failed, so I made a “pneumatic solution dispenser” to achieve the purpose of safe, anti-fouling and convenient in the process of dispensing the solution. 1 Materials and Assembly Balloons
