K-7371S COD Vials Kit

The K-7371S kit comes in a cardboard box and contains 25 vials, enough to perform up to 24 tests and an instruction book. All COD Kits require the use of a Digestor Block and the V-2000 Photometer, an A-7325 COD Photometer, or a spectrophotometer capable of accepting a 16 mm round cell.  Photometers are sold separately. A digestor block is no longer available from CHEMetrics. Contact technical@chemetrics.com 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.
