With OMNIS titrators, you can perform up to four fully automated titrations at the same time. Compared to performing the same application on a stand-alone system, automation will save you up to 60% of time.
Using an OMNIS Sample Robot, you can profit from automated changing of up to 175 samples. Once a rack has been analyzed, it can be replaced without stopping the analysis. With the automation options for OMNIS titrators, you can increase your output without compromising on accuracy.
Some applications cannot be performed using potentiometric sensors. In these cases, sensors observing changes in temperature (i.e., thermometric sensors) are needed.
Thermometric titration is a fast and robust analysis technique for high-throughput routine analysis. You only need one sensor for all thermometric applications. No sensor callibration and, with OMNIS, no additional hardware is required. You can simply upgrade any OMNIS titrator to combine potentiometric and thermometric titration in one system.

Cubis® II from Sartorius has become a fully integrated member of the OMNIS platform. The integration of the high-end Sartorius lab balance allows you to meet superior standards in terms of performance and usability.
Our newly developed patented Liquid Adapter with 3S technology makes chemical handling in your laboratory easier and safer:
Minimize titration errors. LEDs on the instruments show the status of the instrument, indicating if the system is ready or if there is an error. This intuitive concept was also applied to OMNIS Software featuring drag-and-drop functionalities as well as pre-installed methods and context-sensitive help.
Talk to your Metrohm representative and learn about the best solution for your needs!
You can perform up to four fully automated parallel analyses and add automated sample changing of up to 175 samples. Continued operation during rack exchange is ensured.
Thanks to its modularity, you can easily adapt your OMNIS system to increase your output and meet your requirements.
The modular design allows you not only to expand the titration system according to your needs but also to reduce the manual workload in your lab by adding automated sample preparation steps such as pipetting.
OMNIS Software features an intuitive and modern user interface using drag-and-drop functionalities and context-sensitive help elements to make your experience as easy as possible. OMNIS Software is compliant to FDA 21 CFR Part 11 and EudraLex, Volume 4, Annex 11.

A potentiometric titrator uses the difference in potential (mV) between the solution containing the analyte and a reference potential to determine the equivalence point and endpoint of a titration.

The free monograph "Practical titration" covers the theory of titration explaining titration reactions, indication methods, electrodes, and titrants. In the practical part, acid-base, precipitation, redox, complexometric, and chelometric titrations are discussed.
The free monograph "Non-aqueous titration of acids and bases with potentiometric endpoint indication" goes through the process of acid and base titrations.
An automatic titrator, or autotitrator, performs the titration procedure automatically, including results calculation, sample preparation, and series analysis. The steps performed by an automatic titration system from Metrohm are:
Learn more about autotitration and the advantages over manual titration in our blog:
The titrator is equipped with a reference electrode and an indicator electrode or with a combined sensor including both the reference and indicator electrode in one electrode. A stirrer and buret are also needed for potentiometric titrations.
Metrohm offers a variety of electrodes depending on your application. Learn more about electrodes in the following blog articles or documents or find a suitable electrode with our Electrode Finder:
