COD acc. to ISO Precision heating blocks with 6, 12 or 24 sample positions. Flat surface heater for even temperature distribution to each sample position. Stainless steel and powder coated steel casing. Extensive insulation provides for inoffensive temperatures of the casing surfaces.
End-to-end grooves in the precision aluminum plate at the bottom of the bores simplify sample handling and provide for exemplary safety of the analyst:

• During sample insertion the grooves cause pressure compensation. Thus even the most accurately fitting reaction vessels slip easily into the bores, which is required to effortlessly handle the behr insert and yoke type frames for RG 2 reaction vessels.
• When inserting the samples into the hot heating block adherent moisture on the vessel surface evaporates in sudden bursts. The grooves drain off the vapor which otherwise might cause the vessels to jump up and down which might eventually lead to the destruction of the vessels.
• In case of one or more vessels overflowing the liquid COD samples discharge through the grooves minimizing the danger of damages inside the block caused by acids.

The HTI 1 manual titration station consists of

• a burette with digital display and
• a magnetic stirrer with a precisely fitting holder for COD reaction vessels. A screen serves as a neutral background and allows the user to determine the colour change at the end of the titration precisely. Therefore a titration could always carried out under similar visual conditions. This improves the precision and the reproducibility of the results.

The precise positioning of the reaction vessels in the holder on the top of the magnetic stirrer also contributes to this. The angled wing of the screen protects against lateral dazzling light.

Diese Standards sind ideal für die Verwendung als Kontrollstandards, um zu überprüfen, ob eine korrekte CSB-Analyse stattgefunden hat. Umfangreiches Sortiment (10 bis 60000 ppm), rückführbar auf NIST, 2 Jahre lagerfähig. HDPE-Flaschen mit 500 ml Inhalt.

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.
