Compared to conventional boiling stones made of glass, they provide optimum protection against defervescence due to their porosity and their shape, even with badly blended samples. behrotest® boiling stones are chemically pure and guarantee unadulterated results when determining the COD. Article Order No. 4Boiling stones, content 100 g 80 48 30700 Automatic COD Metering Unit DS 20 Metering unit to automate and accelerate the metering of potassium chromate solution and sulphuric acid when preparing COD samples. Metering in a maximum of 12 samples simultaneously. Integrated series magnetic stirrer with 12 sample places. • Metering in optimal time intervals: The metering of sulphuric acid is carried out in several processes, the samples are thus constantly cooled and stirred. This method accelerates the preparation of samples and at the same time prevents non-standard overheating of the samples during addition • Safety for the user: Due to the automatic addition of reagent there is no risk at any time of coming into contact with chemicals • Practice-oriented and user friendly software: The complete programming of the behr DS 20 is very easy to use and user-friendly with the Windows user interface Article Order No. 5DS 20 10 48 24402 for up to 12 samples simultaneously, incl. burettes and cooling trough 6 Fully automatic metering unit/titrator DT 20 Dosing: Time-optimized COD interval dosing. The metering of sulphuric acid is carried out in several processes, the samples are thus constantly cooled and stirred. This method provides for faster sample preparation while preventing a non-standard overheating of samples during addition. Titration: Freely programmable “methods”, f.e. end point titrations, equivalence point titrations, linear, dynamic, and quasi-dynamic titrations. Different, password-protected user levels. Graphic printout with 1st and 2nd derivative. Freely selectable printout of sample data. Compliance with all national COD standards is possible with the “methods”. 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. Safety for the user: Due to the automatic addition of reagent there is no risk at any time of coming into contact with chemicals. • Practice-oriented and user friendly software: The complete programming of the behr DS 20 is very easy to use and user-friendly with the Windows user interface. Article Order No. 6DT 20 10 48 24420 Fully automated dispensing and titration for COD specification pursuant to ISO. Simultaneous dispensing and titration in maximum 12 samples. Automatic extraction of the titrated samples. Particularly easy and user-friendly operation with Microsoft Windows user interface with Access database for further processing of sample data. COD cooling trough The cooling trough prevents the overheating of the COD samples during the critical addition of sulphuric acid. In addition, it is used to cool the samples after the heating phase.
