化学试剂通常称为试剂(reagent),是一大类具有各种标准纯度的纯化学物质,广泛应用于教育、科学研究、分析测试,并作为某些新型工业所需的功能性材料和原料。化学试剂种类繁多,在国际上已达数万种之多,我国也有数千种在日常中使用。
化学试剂的分类方法尚未统一,通常按照学科和实际用途进行划分。例如德国伊默克(E·Merck)公司的目录将其分为十二大类七十小类。大多数国家则根据应用范围来划分。我们主要将试剂分为四类:
通用试剂:泛指符合标准纯度的有机试剂与无机试剂,常用于科学研究、分析测试及合成反应等。
分析试剂:
电子工业试剂:
生化试剂:即生物化学试剂,包括由生物体提取或合成的基本化学物质。主要作为对生物体成分研究和分析鉴定的重要试剂。涵盖临床免疫试剂、基因工程试剂、细胞培养试剂、激素类物质、毒物致癌研究用试剂及防霉杀虫研究用试剂等。这类试剂对于探索生命奥秘、防治疾病等科学研究与检验至关重要,涉及医学和药物学的纯化学制品。
