Fully automated system for determining trace level moisture content
The OMNIS Sample Robot Oven ("OSRO") is a fully automated solution for gas extraction in Karl Fischer titration, designed for solids and other challenging samples. With flexible vial handling, dual oven module options, and seamless integration into the OMNIS platform, it delivers high-throughput, reproducible results with minimal manual intervention
Fully automated gas extraction for solids and difficult samples
Configurable with one or two Oven Modules for maximum throughput
Compatible with a wide range of vial sizes (2R to 30R)
Automatic reagent replacement and methanol refill — no manual interruptions
Gas extraction up to 300 °C with air or nitrogen as carrier gas
Temperature gradient option for optimising unknown samples
Adjustable puncture needle for different vial sizes and filling levels
The OMNIS Sample Robot Oven eliminates manual steps by automatically handling gas extraction, reagent exchange, and methanol refilling. This ensures uninterrupted operation, even during long runs or when working at elevated oven temperatures.
From 2R to 30R vials, the system supports a wide range of sizes and closure types. Mixed vial sizes can be processed in a single sequence, giving laboratories maximum flexibility without the need to standardise vial formats.
The modular design allows you to start with one Oven Module and expand to two whenever your sample throughput increases. This saves space and cost compared to investing in an additional instrument.
As part of the OMNIS platform, the Sample Robot Oven can be combined with Coulometric or Volumetric Karl Fischer Titration modules. This enables unified workflows, centralised control via OMNIS Software, and easy expansion into new titration techniques.

Expand and automate your workflow with modular flexibility. Begin with a single Oven Module and seamlessly upgrade to dual modules for enhanced throughput. Ideal for larger sample batches
Tailor your system to challenging matrices with multiple upgrades:
Second Oven Module: Boost capacity and streamline processing.
OMNIS Dosing Modules: Automate reagent and methanol management for uninterrupted requirements.
Temperature Gradient Function: Optimise heating profiles across different sample types.
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.
