Fully automated acid hydrolysis system. Patented HydroCap™ – single use filter system. Reduced foot print and batch handling of 12 samples.

The HydrotecTM 8000 total fat solution, consisting of an extraction unit, a hydrolysis unit and a FOSS Hydrocap single filter system, allows you to perform total fat analysis in one integrated procedure.

Unique patented filter system

The unique, patented HydrocapTM filter avoids sample transfer and reduces the risk of human error. Laboratory costs are dramatically reduced and higher sample throughput improves cost effectiveness.

Improving throughput at a lower cost

Simplified operation reduces the potential for human error in total fat analysis while reducing costs and improving overall sample throughput.

Reducing risk in total fat analysis

Chemicals are added and removed by pump, improving safety and reducing the risk of error. For total fat analysis, Hydrotec 8000 can be used together with a Soxtec 8000 or ST255 Soxtec extraction unit and FOSS HydroCap single filter that works across both units.

Foss Hydrotec™ 8000

Acid hydrolysis

In some cases, the fat is chemically or mechanically bound to e.g. carbohydrates, salts or proteins. Acid hydrolysis breaks these bonds – making it possible to extract the fat.

Foss Hydrotec™ 8000

Innovative system

  • Chemicals are added and removed by pump, improving safety and reducing the risk of human error
  • Water rinse is performed automatically
  • The system is closed and releases no fumes

Foss Hydrotec™ 8000

Simplified process

This unique patented Hydrocap™ filter contains the sample from the initial weighing, through hydrolysis to final extraction; avoiding sample transfer errors. It is a fully automated system that performs automated acid hydrolysis and Randall improved Soxhlet extraction in one integrated process.

Batch handling tools

Batch handling, with no sample transfer, is used throughout the procedure. Boiling, rinsing and filtration are performed under reproducible and controlled conditions. The system offers substantial savings in terms of operator time, as well as improved analytical precision compared to manual methods.

How to Do Total Fat Analysis with The Soxtec 8000 System

Foss Analytical

FOSS creates end-to-end solutions that secure and improve food quality. From raw material to finished product. Our analysis instruments refine measurements into information management that enables businesses to run intelligent data-driven productions with less waste and bigger yields. Controlling cost and quality across all sectors and value chains, we help food and agricultural producers limit the number of human errors, scale their business faster and reduce manual labor as well as labor costs. We call it analytics beyond measure.

We cover these food and agricultural industries: Dairy, Feed and Forage, Grain, Flour Milling & Oilseed Processing, Laboratories, Meat, Raw Milk Testing and Wine.

Over the last 60 years, we have made it our business to define the standard of analytical solutions for the food and agricultural industry. We pioneered advanced analysis for the challenging production environments in the 1960’s, and we were the first to integrate chemical composition analysis in process lines. Now our resolve and ambition have also made us the international benchmark in the field of chemometrics and real time analytics.
