Kit comes in a cardboard box and contains everything needed to perform up to 29 tests (except distilled water): thirty ampoules1, Activator Solution, Neutralizer Solution2, 25 mL sample cup, ampoule blank, 1.0 mL syringe, and instructions.
Vacu-vials Kits require the use of the V-2000 Photometer or a spectrophotometer capable of accepting a 13 mm diameter round cell. Instrument sold separately.
1Although the test kit contains 30 ampoules, a fresh reagent ampoule blank must be prepared for each series of tests; therefore, the number of samples that can be tested with each kit will vary from a maximum of 29 to a minimum of 15.
2The Neutralizer Solution is supplied as a dry chemical with NO expiration date. Once reconstituted, it has a shelf-life of 6 weeks that can be extended to 3 months if stored in the refrigerator when not in use.

铬花青R（ECR）法测定水中的铝，Keneth E Shull和Gene R. Guthan, 第1456-1468页, J.AWWA(美国自来水协会),1967年11月。
铝在地球表层形成多种矿物质。铝及其合金有很多用途：热交换器、结构材料、飞行器部件等。铝（硫酸铝钾）用在水处理中作为悬浮颗粒的絮凝剂，但是他的使用可能导致最终饮用水中铝的浓度升高。饮用水的最大二次污染允许限度为0.05—0.2mg/L。
铝的Vacu-vials®测试方法是以铝和铬花青R（ECR）之间的反应为基础的，这两种物质在pH值接近6.0时，反应形成一种红色色淀，这种色淀的形成于样品中的铝的数量成比例。测量结果用ppm铝表示。
