SoxROC Automated Hot Solvent Instrument


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.

Batch Handling

The SoxRoc's innovative batch handling improves lab efficiency while promoting operator safety.

The SoxRoc uses a single tray to hold all sample cups, making sample preparation, loading and unloading fast and easy.

The thimbles always remain in the cup to reduce the risk of spilling solvents onto the hot plate.

Add Flexibility. Add Safety.


Unique control of solvent removal adds flexibility for different applications.

Security with high standard against dust, liquids and explosives. All valves close to solvents are ATEX classified.

Operator safety is important and the SoxROC is equipped with protection shield, closed addition of solvents, and easy removal of recovered solvents.

Reduce Time. Reduce Errors.


With SoxROC, you can extract as many as 42 samples per day with no loss in precision or accuracy.

Automation of all extraction steps and an innovative batch handling reduces risk for errors. Typically up to five times faster than the classical Soxhlet technique.

Reduce Costs

Unique sealing system with more than 90% recovery reduces cost for solvents and efficient water cooling reduce water consumption.A large selection of seals, cups and standard thimbles reduces costs when changing between applications and solvents. One single compact system without wires or computers reduces costs for installation and operation.
