现有玻璃滴管上的胶帽,很容易被蒸发或倒流的化学药剂腐蚀,需要经常更换,耗费实验教师的精力,同时增加了学校实验经费的开支,而更换下来的胶帽又给环境增添了一份新的污染。为了解决这一问题,我通过长时间的思索和反复的对比实验,设计了防腐蚀玻璃滴管。一、实验材料及组装 The existing plastic cap on the glass dropper is easily corroded by chemical agents that are evaporated or backdated and need to be replaced frequently, consuming the energy of experimental teachers and increasing the expenditure on experimental expenses of the school. The replacement rubber cap adds to the environment A new pollution. In order to solve this problem, I designed anti-corrosion glass dropper through long time thinking and repeated comparative experiments. First, the experimental materials and assembly
