KjelROC Automated Kjeldahl Analyzer


KjelROC Analyzer

The KjelROC range of automatic Kjeldahl analyzers offers innovative, precise and cost efficient solutions for distillation, titration and determination of protein/nitrogen according to the Kjeldahl method.


The Kjeldahl apparatus provides steam distillation according to official methods and the OPSIS LiquidLINE unique Predictive Titration, patent pending, offers fast and highly repeatable results.

Automating Kjeldahl Analysis

The OPSIS LiquidLINE KjelrROC automates traditional Kjeldahl analysis to improve laboratory throughput while making the analytical procedure safer.

The easy to use touch screen simplifies routine analysis by allowing the operator to manage all functions of the analytical procedure and calculations.

The KjelROC is available in multiple levels of automation from a basic distillation unit to a full analyzer with automated titration.

Increase Efficiency. Reduce Costs


The possibility to send and receive results without additional software, computers and cables, significantly reduces the integration and IT costs.


Process data files directly in the KjelROC Analyzer. This reduces costs when integrating with your LIMS or other systems.

Low Maintenance Costs


Prepared for ISO 17025 and GLP features, reduce time and costs when integrating the instrument into the Lab procedures.


Component lifetime and maintenance costs are optimized with the help of OPSIS component traceability program. It allows easy diagnostics and follow-up of both instruments and components.  

Adaptive Workflow


The KjelROC Analyzer is fully flexible to adapt to your existing lab procedures or you can use our ready to use programs.


You are always in control with our customizable touch screen, where you can define your own workflow.

Predictive Titration

The unique patent pending predicive titration system lowers the Relative Standard Deviation (RSD) of analysis for repeatable and reliable results.


The ability to titrate in parallel with distillation streamlines analysis to optimize sample throughput.


The 50 ml burette with automatic refill makes it easy to change between high and low protein analysis.

KjelROC Autosampler


The KjelROC Autosampler provides laboratories with an innovative instrument that determines protein and nitrogen according to the Kjeldahl method.


The KjelROC Autosampler is fully automatic and is able to handle up to 25 different samples automatically.


The principle is simple, insert a tube rack with samples and return later to collect the results.


The KjelROC Automsampler is a Kjeldahl apparatus capable of steam distillation, titration and automatic exchange of samples.
