日常生活中一些小药瓶(如青霉素瓶等)随处可见,只要科学老师做个有心人,小药瓶也可以在科学课实验中派上大用场。 将小药瓶的橡胶塞取下,用钉子钻一个小孔,插入一根去掉笔尖的圆珠笔芯或细塑料管,把细塑料管在火焰上烘一烘,弯成需要的角度,这样一个带塞子和导管的微型烧瓶就做成了。小药瓶还可当作微型试管、集气瓶、标本瓶、培养皿等,用来完成各种实验。 Some small bottles of daily life (such as penicillin bottles, etc.) can be seen everywhere, as long as the science teacher be considerate, small bottles can also be used in scientific experiments. Remove the rubber stopper from the vial, drill a hole with a nail, insert a ballpoint pen tip or thin plastic tube with the nib removed, bend the thin plastic tube over the flame, bend it to the desired angle, Miniature flasks and catheters were made. Small bottles can also be used as micro test tubes, gas cylinders, specimen bottles, petri dishes, used to complete a variety of experiments.
