Soxtec™ 8000 Extraction Unit

Tecator Line Fully Automated Extraction Unit – Soxtec™ 8000

The Soxtec™ 8000 extraction unit is a fully automated system for fast and safe extraction of soluble matter from a wide range of matrices. It performs the four extraction steps boiling, rinsing, solvent recovery and auto-shut down, fully unattended. Just load, start and walk away.

The Soxtec™ 8000 Total Fat solution helps you respond to the demands of your customers, for example, you can do Total or Crude Fat analysis or both. It’s easy to increase capacity according to customer requirements with up to 12 position hydrolysis and six position extraction that is expandable to 12, all with individual hotplate control.

Soxtec integrated total fat analysis

The FOSS total fat solution allows you to perform total fat analysis with one integrated process. There are three main elements to the solution: the Hydrotec™ 8000 hydrolysis unit, the Soxtec™ 8000 extraction unit and the Hydrocap that works in both. The extraction unit has an external controller and a broad range of accessories.

The Hydrotec™ 8000 unit performs automated acid hydrolysis of samples to break up bonds between fat and other components. Traditionally, hydrolysis units have a capacity of up to six samples and, at this capacity, instruments take up a lot of bench space in the laboratory. The Hydrotec™ 8000 changes that paradigm. It has a twelve place sample holder with a folding action so that samples to fit neatly into the hydrolysis unit.
Chemicals are added and removed by pump, improving safety and reducing the risk of human error.
After hydrolysis the samples and Hydrocaps are dried and placed in the specially designed tool for transferring to the extraction unit in sets of six hydrolysed samples.
The filter is made of an inert material that retains the fat during hydrolysis, but releases it during extraction.

The Soxtec™ 8000 extraction unit is a fully automated system for fast and safe determinations of extractable matter. For total fat analysis, the Hydrocap filter is transferred from the hydrolysis unit to the extraction unit which then performs the four extraction steps boiling, rinsing, solvent recovery and auto shut down, fully unattended. Just load and start.
