Opsis LiquidLINE products:

KjelROC digestion system

Standard in all our digestion blocks are selectable programs, timer functions and possibility to select between Celcius and Fahrenheit. Our more advanced blocks offer an automatic motor rack.

Automatic Programs Saves Time

Automatic programs make the KjelROC Digestors easy to use. Alarm signal and/or automatic cooling simplifies the surveillance of the process.

Automation Saves Time and Reduce Costs

KjelROC Digestors Advanced models saves even more time with fully automatic motor rack.

Lower Maintenance Costs

All Digestors and Scrubbers built with high endurance materials. From high quality borosilicate glass to high quality EN 1.4404 stainless steel.


KjelROC Scrubber

Environmental concerns are always important to consider and therefore we recommend to use scrubbers together with our KjelROC Digeston blocks.

Reliable and Easy with a Small Footprint

The KjelROC Scrubbers are built to work in an environment with high corrosive fumes and high temperatures. All materials are carefully selected. Small footprint and ease of use has been prioritized when designing the OPSIS KjelROC Scrubbers. No water is required for installation and use.

High Standard

All KjelROC scrubbers can be supplied with optional water cooler and water traps for additional efficiency during extraction.

KjelROC Distillation unit

Our KjelROC Distillation unit offers full control of the distillation process at a low cost. The instrument is a Kjeldahl apparatus with full control of alkali, water, and steam. There are two versions of the steam distillation system - one with automatic addition of receiver solution and one without. All our KjelROC models can be upgraded.

Expandable System. Low Cost for Upgrade

The KjelROC Distillation Unit can easily be upgraded to a full KjelROC Analyzer or an Autosampler.

Automation and Traceability. Increased Efficiency

The KjelROC Distillation Unit is completely automatic with programmable addition of alkali, water, and receiver solution. There is full traceability with the possibility to track samples as well as retrieve log files from the instrument. The Automatic Distillation unit is also delivered together with the OPSIS LiquidLINE LabConnect software which makes it even easier to manage your results. The automatic unit can be connected to external titrators.

Chemical Resistance

The OPSIS LiquidLINE BlackLINE coating provides a unique corrosion protection. Our instruments are Prepared for ISO 17025 and GLP features, reduce time and costs when integrating the instrument into the Lab procedures.


KjelROC Analyzer

Our KjelROC range of automatic Kjeldahl analyzers offers innovative, precise and cost efficient solutions for distillation, titration and determination of protein according to the Kjeldahl method. The Kjeldahl apparatus provides steam distillation according to official methods and the OPSIS LiquidLINE unique predictive titration gives several advantages in the lab.

HydROC Hydrolysis unit and  FiberROC

OPSIS LiquidLINE brings an innovative solution for acid hydrolysis, making total fat determinations more efficient and safe. The hazardous hydrolysis process can now safely be performed with up to six samples simultaneously. The unique HydROC filter brings additional cost and time savings.


The OPSIS LiquidLINE HydROC unit can be further expanded with a Fiber analysis kit.


The expansion kit consist of specific boiling cups and OPSIS LiquidLINE unique fiber bags for analysis according to the Weende method (Crude Fiber).

SoxROC Extraction unit


The OPSIS LiquidLINE SoxROC Extraction Unit is an automated hot solvent instrument that can extract fat according to official methods. The instrument is based on Randall and Twisselmann techniques, using hot solvent and a closed system to reduce extraction time versus manual Soxhlet. The SoxROC follows officially approved methods for fat extraction.

The SoxROC is designed to be flexible and is therefore also capable of extractions using other solvents and samples. Available in 2 and 6 position models.
