由于经常添加和取用试剂,液体难免沾染试剂瓶标签,使之受到腐蚀而字迹模糊,因此标签需要经常更换,费时费力,下面我来介绍一种标签的简单封存法: 1 材料 二甲苯,防震泡沫(一些产品的包装箱内有)。 2 作法 将防震泡沫溶解在二甲苯中,使之尽量(?)到饱和,形成粘稠液(可用烧杯),然后找来一支 Due to the frequent addition and retrieval of reagents, liquids are inevitably contaminated with the label of reagent bottles, causing them to be corroded and illegible. Therefore, the labels need to be replaced frequently, which takes time and effort. Here’s a simple sealing method for labels: 1 xylene, shockproof Foam (some products are in the box). 2 Practice Dissolve anti-shock foam in xylene to make it as saturated as possible to form a viscous liquid (available for beakers), and then find a
