Extraction Solutions

We offer BUCHI’s dedicated extraction solutions for the classical determination of fat (FatExtractor E-500) as well as for residue and contaminant analysis in various matrices (UniversalExtractor E-800, SpeedExtractor E-914 / E916). BUCHI’s extraction systems cover the whole range of automated extraction methods from Soxhlet to hot extraction and pressurized solvent extraction (PSE). These solutions allow for ideal integration in the workflow, thus minimizing manual steps. As a sample preparation step prior to fat extraction, acid hydrolysis can be performed using the HydrolEx H-506 sample preparation system.


BÜCHI Labortechnik AG
The UniversalExtractor E-800 with its six distinct extraction positions enables individual process control and simultaneous operation of different extraction methods. Multiple work packages can be executed in parallel, which allows for faster method development and higher sample throughput. High-speed heaters combined with sophisticated process control permit fast and highly reproducible extraction processes. The large condenser captures vapors efficiently and ensures highest solvent recovery (>90%). Full extraction process visibility is enabled by the glass assemblies. All components that are in contact with the sample and the solvents are made of completely inert material, which eliminates sample contamination and any memory effects from leaching materials.

The UniversalExtractor can be employed in chemical, pharmaceutical, feed and food extraction as well as in environmental analysis. Viac info

BÜCHI Labortechnik AG
The FatExtractor E-500 is designed for solid-liquid extraction for quick and compliant fat determination. The design of the glass assemblies and the high-speed heaters combined with sophisticated process control allow for fast and highly reproducible extraction processes with full compliance. With the interchangeable glass assembly, executing extractions according to Soxhlet, Randall or Twisselmann (ECE) and a later conversion to another extraction method is possible - adaptable to needs and changing demands. Using high-end components such as optical sensor, powerful heating and optimized glass assembly, cycle times can be significantly reduced. Benefit from the reduced time-to-result and unprecedent daily sample throughput.

The FatExtractor can be employed in the food and feed extraction and is suitable for extractions with petroleum ether, diethyl ether, hexane or chloroform. Viac info

BÜCHI Labortechnik AG
The HydrolEx H-506 performs acid hydrolysis as a sample preparation step prior to fat extraction for total fat determination. It supports large sample volumes of up to 10 gram samples for accurate results, independent of fat content or homogeneity. The HydrolEx H-506 offers a smooth and safe process with convenient system handling, assuring conformity with official regulations for the declaration of total fat content. The standardized and exhaustive procedure guarantees reproducible results. The HydrolEx H-506 offers a convenient transfer of the hydrolyzed sample into the Soxhlet extraction chamber with reusable glass sample tubes and the specialized glass samples tube fits perfectly into the FatExtractor E-500.

The HydrolEx H-506 can be applied in food and feed extraction for the determination of crude and total fat, lipids (after hydrolysis), food contaminants and residues. Viac info
