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, instructions, and MSDS.

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.
