1235 12. Environmental-, soil-, water-, food analysis Sample analysis/COD GENERAL CATALOGUE EDITION 20 E & OE. COD metering funnel COD metering funnels, placed on top of the COD reaction vessels, simplify the addition of sulphuric acid to several samples simultaneously. COD metering funnel together with a cooling trough and a series magnetic stirrer increase the safety and offer considerable relief to the user when determining the COD. 1 behr Type Description PK Cat. No. DT 30 metering funnel, 30 ml, for sulphuric acid 1 9.920 713 1 HCl-absorber To expel chloride, e.g. when determining the COD of sea water. 2 behr Type Description PK Cat. No. HCL 29 HCL absorber to expel chloride 1 6.060 789 2 Automatic metering and titration unit DT 20 Dosage: Time optimized COD interval dosage. The addition of sulfuric acid is carried out in several steps, while the samples are constantly cooled and stirred. This method accelerates sample preparation and at the same time prevents non-standard overheating of the samples during acid addition. Titration: Instead of the commonly known over-titration, the behr-specific dynamic titration guarantees the exact end-point recognition, even in the case of the typical COD edge steepness, and thus particularly accurate test results 3 behr Type Description PK Cat. No. DT 20 Automatic metering and titration 1 9.920 748 3 Chemical Oxygen Demand (COD) Standards These standards are ideal for use as Control Standards to verify that correct analysis for COD has taken place. Extensive range (10 to 60.000 ppm), NIST traceable, 2 years shelf-life. HDPE bottle of 500 ml. 4 Reagecon Type Measuring range PK Cat.
