COD Vials Kit

Catalog No.: K-7355*
Range: 0-150 ppm (LR) USEPA-accepted
Method: Dichromate Reactor Digestion

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 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.
