化学试剂
化学试剂,简称试剂,是一类具有各种纯度标准,用于教学、科学研究、分析测试,并可作为某些新兴工业所需的纯和特纯的功能材料和原料的精细化学品。它一般可按组成和纯度来进行分类。
按组成/用途分类: 按纯度/规格分类:目前中国主要划分为高纯、光谱纯、基准、分光纯、优级纯、分析纯和化学纯等7种,其中主要为优级纯、分析纯和化学纯三种。选用不同纯度试剂的标准主要是不同的反应需求,以及该试剂所含杂质对分析要求有无影响。 国家或国务院有关行政主管部门颁布质量指标的主要是优级纯、分析纯和化学纯三种。这三种试剂对比如下: 普通化学试剂一般以玻璃瓶、塑料瓶或塑料袋盛装,并在其上贴有标签注明试剂的基本性质。

Reagent 化学试剂
A reagent is a substance or compound added to a system to cause a chemical reaction, or added to see if a reaction occurs. The terms reactant and reagent are often used interchangeably—however, a reactant is more specifically a substance consumed in the course of a chemical reaction. Solvents, though involved in the reaction, are usually not called reactants. Similarly, catalysts are not consumed by the reaction, so are not reactants.
