OMNIS – Titration on a whole new level

Metrohm has reinvented titration: Discover OMNIS.

OMNIS is Metrohm’s new, fully integrated titration system that caters to the needs of today’s laboratories.

With OMNIS, we have gone beyond just creating a new titrator. We have put your requirements and your laboratory in the focus to develop a titration solution that simply offers more: faster results, more safety, more convenience, more efficiency – in short: performance on a whole new level.

Getting results: FASTER!

Get four times the output with OMNIS.

OMNIS is capable of performing four fully automated analyses at the same time. And when free capacities are identified, instead of being idle, the system continues with the subsequent analyses – automatically!

Working with OMNIS: SAFER!

Make your lab safer with 3S adapter technology.

We have made chemical handling easier and safer. The result is our patented Liquid Adapter with 3S Technology. 3S stands for:

  • Safe chemical handling: Just snap the adapter onto the bottle cap and avoid contact with the bottle contents.
  • Secure information transfer: The RFID chip in the bottle cap provides all relevant information on the content of the bottle.
  • Smart connection: The reagent data is automatically transmitted to the titration system.

Using the OMNIS software: EASIER!

Experience a software solution designed for the future: intuitive, easy-to-use, and intelligent. Graphical representations of hardware components, drag-&-drop functionality, and context-sensitive operation make your work in the lab as easy and efficient as possible.

User guidance tailored to the users: The OMNIS software is based on concepts, processes, and requirements of chemical laboratories. It thus offers an unparalleled user experience:

  • Visual status indicators
  • Alerts, system checks, and suggestions
  • Freedom in editing templates for methods, processes, commands, etc.

Scaling up your lab: SMARTER!

Expand your system as you go. Start with a single OMNIS titrator and add titration and dosing modules when needed. By including additional measuring interfaces and burets, you can have up to five different applications ready for use – even in parallel.

If sample throughput is increasing, add an OMNIS Sample Robot for fully automated titration. Thanks to modular work stations, racks, and pumps, OMNIS is capable of analyzing four samples in parallel.
