behrotest DT 20

The fully automated metering unit / titrator DT20 is the the perfect supplementation of the COD program for laboratories with high sample volume. It automates and accelerates the stations considerably during COD determination.

behrotest DT20 combines and automate during COD determination, the metering of calcium chromate solution and concentrated sulfuric acid and then the subsequent titration.

This way, behrotest DT20 makes work easier for the user and helps save time and costs.

Optimized sample preparation

With its time-optimized interval metering function, behrotest DT20 considerably facilitates the time-consuming process of COD sample preparation. At this same time, this metering method prevents the behrotest from causing non-DIN/DEV-compliant overheating of the samples when adding sulfuric acid.

Security in every phase

Thanks to the automatic reagent addition, during metering as well as titration, there never is a risk of coming into contact with the chemicals.

Reagent monitor

During metering as well as titrating, reagent monitors ensure that there is a sufficient amount of chemicals in the bottles at the beginning of the action. Examinations that fail as a result of lacking reagents are ruled out.

Complete distillation equipment consists of a base stand with specially adjustable flowmeter 10-100 I/H and condenser stand, adjustable heating unit, glass set with flasks, condensate reservoir, condenser and gas line connection incl. cooling water hoses

behrotest ® distillation equipment to determine the phenol index in accordance with DIN / DEV 38409 - H 16 and the ammonium nitrogen in accordance with DIN / DEV 38406 – E 5

The carbonate content of the soil is a reliable indicator for the fertility of soil. behrotest® Calcimeter were developed for the determination of carbon content in up to five samples, e.g. in agricultural areas, winegrowing, in pomicutura, etc. They comply with ISO 10693, DIN 19682 and DIN 19684.

Sample preparation for hydrocarbon determination in accordance with DIN/ISO includes of the following behrotest equipment:

1. Extraction unit EX 1000

2. Clean-up station CUS 2

3. Nitrogen station KOSTA 2

4. Centrifuge glass ZG50

Precise analysis is guaranteed with the highest possible workmanship of the constructed behrotest glass form and the exact graduation of the glass.

behrotest® extraction apparatus for the determination of formaldehyde content in accordance with DIN EN ISO 12460-5:2016-5

DIN EN ISO 12460-5:2016-5 specifies an extraction method known as the "perforator method". It is used to determine the formaldehyde content of uncoated and unpainted wood materials. The purpose of the perforator method is the in-house production control of formaldehyde emission of wood-based materials. Formaldehyde is extracted from test objects with boiling toluene and released to distilled or demineralized water. The formaldehyde content of this aqueous solution is determined photometrically using the acetylacetone method.

The workstation behrotest® PI 12 is used to determine the permanganate index in water according to DIN EN ISO 8467. Thus, especially drinking and raw water, as well as source and surface water is assessed. The method is suitable for the waters with a chloride concentration of less than 300 mg/L.
