Boiling stones behrotest®
behrotest® boiling stones are made from a ceramic material. 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, the Kjeldahl nitrogen etc.

Thermoreactor with pre-programmed and user-defined programmes for the digestion of standard parameters in reaction cuvettes. The CR4200 allows standard-compliant digestions with programmes for the standard parameters COD, total nitrogen, total phosphorus, TOC and heavy metals in galvanisation. In addition, 8 separate programmes can be created for special digestions at temperatures between room temperature (25 °C) and 170 °C. Independent thermoblocks allow 2 different programmes to be run simultaneously.2 independent thermoblocks with 12 holes each for reaction cells with an outer diameter of 16 mm8 stored programmes for all important digestions: 148 °C for 120 min; 148 °C for 20 min; 120 °C for 30 min; 120 °C for 60 min; 120 °C for 120 min; 150 °C for 120 min; 100 °C for 60 min, 100 °C for 30 minAutomatic temperature switch-off at the end of the set programmeAQA/IQK with optional external temperature sensor for documentationPower supply 115/230 VAC, 50/60 Hz
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 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.
Programmable control unit for behrotest® digester blocks.behr one-button operation for particularly easy and quick programming. Menu navigation in the language of the country. 10 optionally configurable programs for block temperature and digestion time.The TRS 300 has a special COD program which has already been set by the plant. Therefore in the operation mode "COD" it heats up to a temperature which is 20°C above the set target temperature. After inserting the samples, the 20°C higher target value remains for another 6 minutes. This procedure ensures heating up to 148°C within 10 minutes which is specified by the ISO norm, and at the same time causes extremely high temperature constancy during the subsequent reaction process. The supplied Windows software permits the user to transfer time/temperatures profiles, which are specifically for the application, via the RS232 interface in both directions between one or more units (TRS 300) and a PC. Temperature data can also be transmitted from the unit to the PC via the RS232 interface while operating. The user can save them if necessary and print them out as graphics. Integrated safety function switches the connected units off if there is a short-circuit and an interruption of the temperature sensor.
