酒精灯使用
火焰分为三层：焰心、內焰、外焰，外焰温度最高
酒精量不超过容积的2/3，不少于1/4
用火柴点燃，禁止向燃着的酒精灯内添加酒精，禁 止用燃着的酒精灯引燃另一个酒精灯
熄灭必须用灯帽，方法：用灯帽盖灭，轻提一下重 新盖好
物质的加热
固体加热
试管口略向下倾斜，防止冷凝水回流炸裂试管 先用酒精灯量 人工合成牛胰岛素、核糖核酸等

常见的仪器
不用手直接接触药品 不把鼻子凑到容器口闻药品的气味
不品尝任何药品的味道
“三不“原则
若规定用量，则按照规定量取用
若无规定用量，固体药品盖满试管底 即可，液体药品取1~2mL
节约原则
取用原则
剩余药品不放回原品，也不随意丢弃，放在指定容器中
处理原则
块状或颗粒固体：一横二放三慢竖 粉末状固体：一斜二送三直立
固体药品的取用
药品的取用
较多量：倾倒法，瓶塞倒放，标签朝向手心，瓶口与容器口紧挨
取用方法 液体药品的取用
较少量：用胶头滴管滴加，注意“垂直悬空” 极少量：用玻璃棒蘸取
先倾倒至接近所需刻度，改用胶头滴管滴加 读数时，视线与凹液面最低点相平
