797 VA Computrace System for trace analysis with automatic standard addition

The right system for every need
The MVA Systems (Metrohm VA Systems) are sets of instruments customized to meet particular demands. Choose the set that meets your requirements, connect it to a PC and a supply of nitrogen (if required for the particular system), and you are ready to go.
The systems provide different degrees of automation, depending on the number of samples to be analysed. They can be used as stand-alone or PC controlled systems.

MVA-02 797 VA Computrace System for trace analysis with automatic standard addition
	Analysis system for voltammetric trace analysis and education. Comprised of 797 VA Computrace with two 800 Dosinos for the automatic addition of auxiliary solutions. Without PC.

MVA-02 797 VA Computrace System for trace analysis with automatic standard addition

Partially automated voltammetry system for routine trace analysis

MVA-02 is a simple-to-operate, partially automated VA system for routine trace analysis. Two auxiliary solutions (standard and electrolyte) can be added automatically to the measuring vessel. The sample, however, is handled manually. Simply place the sample in the measuring vessel with the aid of a pipette, start the analysis and you will receive the result. This system is intended for users who value elegant and convenient operation at an attractive price without having to use a sample changer.

The core of the system is the 797 VA Computrace, which is supplemented with two 800 Dosinos that are used for adding the solutions.Of course, the Dosinos are completely controlled by the 797 VA Computrace. One additional 800 Dosino can be connected directly, as can four additional ones with the aid of an 846 Dosing Interface. A maximum of seven 800 Dosinos can thus be used.
