Clever liquid handling that simplifies your work


The 894 Professional CVS reduces user interaction by using Metrohm’s Dosinos for automatic dosing of sample and solutions.

You can further complete your system’s liquid handling with pumps for automatic rinsing. Optional level sensors send out timely warnings when waste containers are full and thereby prevent them from overflowing.










viva – the powerful CVS software


The 894 Professional CVS family is operated by viva, Metrohm’s CVS software.

It takes care of everything from the management of the sample data, instrument operation, data recording, and evaluation to results management in its own database.

Create methods to match your applications


The preprogrammed methods available in viva cover common standard applications.

However, the software also allows you to detach yourself from these methods: viva is the only CVS software at the market that offers the possibility of intuitive and problem-focused method programming with its integrated method editor.

This gives you complete freedom of applications.












Built-in intelligence improves accuracy and saves time


viva can automatically adapt the method settings to sample properties – and thereby improve result accuracy and method application range, while reducing test time.















Accurate and reliable


The 894 Professional CVS features an integrated calibrator and a newly designed potentiostat/galvanostat which make it highly sensitive and guarantee accurate and reliable results.















More than one application?


No problem!

The exchangeable measuring head allows you to switch between different applications in a matter of seconds. All of the electrodes and tubing connections are replaced in three rapid steps.
