The K-7355 kit comes in a cardboard box and contains 150 vials, enough to perform up to 149 tests, and instruction book.
All COD Kits require the use of a Digestor Block and the V-2000 Photometer, a A-7320 COD Photometer, or a spectrophotometer capable of accepting a 16 mm round cell. Photometers sold separately. A digestor block is no longer available from CHEMetrics. Contact firstname.lastname@example.org for recommendations.
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.
