Opsis was founded in 1985 by two professors from Lund with the idea of achieving greater accuracy in monitoring gas and airborne pollutants. Since then, Opsis has become a world leader in the monitoring of air, and their monitoring equipment has been installed all over the world. At the beginning of the year 2000, the area of application was extended to also include liquid, and

Opsis LiquidLINE was founded. Avalon Innovation and Opsis LiquidLINE started a collaboration, and so far we have developed five internationally successful instruments together: KjelROC Analyzer, KjelROC Distiller, KjelROC Digestor, SoxROC Extraction Unit and HydROC Hydrolysis Unit.


The KjelROC Analyzer is an instrument that has been optimised to measure, for example, protein in food. The KjelRoc Analyser also has the facility to transmit information digitally, and users have test results sent directly to their mobile device. This makes information management both smooth and cost-efficient. This work resulted in a technology that enables extremely accurate measurements and that has also been patented. Within the project, we contributed competence in the areas of design, mechanical engineering, electronics and programming.

We were involved in parallel in the development of the KjelROC Distiller, an instrument for the manufacturing of distilled water, and the KjelROC Digestor. The latter is a digestion block for boiling samples in solvents, which speeds up the subsequent analysis in the KjelROC Analyzer. The KjelROC range was well received in the market when it was launched, making a name for Opsis LiquidLINE in laboratories all over the world.

The SoxROC Extraction Unit, which was our next project together, is used to extract fats to measure them in food. In this project, Avalon provided competence in the areas of mechanical engineering and programming. This work resulted in a new, effective seal that enables the highest recovery of solvents in the market. This is both cost-efficient and good for the operator, as a lower level of solvents is released into the air. The instrument is also unique, as the test cups are in a “W” formation, which means that the instrument takes up less space on the worktop than corresponding competitors. All electronic control components are integrated in a pressurised electronic box, resulting in an extremely high level of safety. This enables the instrument to achieve IP55 classification. The fruit of our latest collaboration, the HydROC Hydrolysis Unit, is used to dissolve food samples before fat is extracted in the SoxROC Extraction Unit. We supported Opsis in this project with expertise in the field of mechanical engineering.

“We’re really satisfied with the collaboration with Avalon Innovation. It’s a partnership that has resulted in product development that is both efficient and fast. Avalon Innovation has made it possible for us to focus on sales, customers and our products’ properties, while they have taken care of the detailed design of software and hardware. I can recommend Avalon Innovation to any company that’s looking for a reliable partner for their product development.”
