谢谢了
要原因
刚入这行,谢谢大家
通过解答,教会我,谢谢

请问下有无同学需要H37RA的?我是做EAE模型的,上个月购买了BDDifco公司的H37RA(货号),因为购买的时候只能整盒6支购买,但我们用不了那么多,所以想问问有无同学需要的,100mg/支,800元/支或用等价试剂交换。地址广州。有需要的请私信,谢谢!
(1)优级纯试剂 亦称保证试剂,为一级品,纯度高,杂质极少,主要用于精密分析和科学研究,常以GR表示。
(2)分析纯试剂 亦称分析试剂,为二级品,纯度略低于优级纯,杂质含量略高于优级纯,适用于重要分析和一般性研究工作,常以AR表示。
(3)化学纯试剂 为三级品,纯度较分析纯差,但高于实验试剂,适用于工厂、学校一般性的分析工作,常以CP表示。
(4)实验试剂 为四级品,纯度比化学纯差,但比工业品纯度高,主要用于一般化学实验,不能用于分析工作,常以 LR表示。
以上按试剂纯度的分类法已在我国通用。根据化学工业部颁布的“化学试剂包装及标志”的规定,化学试剂的不同等级分别用各种不同的颜色来标志,见表1。
