** Refers to the reagent number in the kit.For example, reagent number 1 = HR2-428-01
The individual reagents 1 (A1) to 96 (H12) in the Additive Screen and Additive Screen HT are identical and use the same Additive Screen Custom Shop catalog number. Reagent is supplied in a 1.0 ml volume in an o-ring screw cap polypropylene tube.
June 2008 reagent 89(H5) changed to 40% v/v Formamide.
For Additive Screen reagent 51(E3) Dextran sulfate, please order HR2-428-51A for Additive Screen kits lot 2428xx where xx = 11-12, and order HR2-428-51B for Additive Screen kits lot 2428zz where zz = 1-10 or >12.
For Additive Screen HT reagent E3(51) Dextran sulfate, please order HR2-428-51A for Additive Screen HT kits lots 213806, 213807 and 213808, and order HR2-428-51B for Additive Screen HT kits lot 2138zz where zz = 1-5 or >8.
For Additive Screen reagent 68(F8) CYMAL-7, please order HR2-428-68A for Additive Screen kits lot 2428xx where xx = 07-17, and order HR2-428-68B 1,2,3-Heptanetriol for Additive Screen kits lot 2428zz where zz is greater than or equal to 18.

D.HNO3KOHKClK2CO3
（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。
