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.

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. More information

The SpeedExtractor with its automated sealing is the ideal solution for fast Pressurized Solvent Extraction (PSE), increasing productivity and throughput by processing up to 6 samples in parallel (up to 96 samples in an 8hour shift). The high level of automation, the ease of sample loading and the ready-to-use extract collection enable the workflow of the sample preparation to be streamlined and increase safety. The wide temperature and pressure range, sample volumes from 1 to 120 mL and the integrated mixer for up to 4 solvents allow to reliably extract complex matrices with high recovery of the analytes. The full compatibility of the SpeedExtractor collection glassware with Syncore® Analyst, Multivapor™ and Sepacore® ensure a continuous workflow and high sample throughput.

The SpeedExtractor can be employed in chemical, pharmaceutical, feed and food extraction as well as in environmental analysis and scientific research. More information
