Available models

Quick and compliant

The FatExtractor E-500 is designed for quick and compliant fat extraction. Gain the flexibility to readily adapt your FatExtractor E-500 to changing needs with the interchangeable glass assembly and execute extractions according to Soxhlet, Randall or Twisselmann.


  • True Soxhlet
    • Soxhlet extraction is exhaustive and rugged but is still the mostly used and regulatorily demanded method for many sample matrices
    • Analytical risks or time-consuming validation of other extraction methods deviating from the standard do not exist
    • Used as reference method for NIR calibrations
  • Soxhlet extraction made faster
    • Reduced cycle times are the result using of high-end components such as optical sensor, powerful heating and optimized glass assembly
    • Automated Soxhlet process reaches an unmatched speed compared to traditional glassware assemblies
    • Reduced time-to-result and unprecedent sample throughput per day
  • Interchange between glass assemblies (SOX-HE-ECE)
    • Easy change of glass assembly that is compliant with Soxhlet, Randall (HE) and Twisselmann (ECE)
    • No limitation to one extraction method, but adaptable to needs and changing demands
    • Profit from unrivalled quick extraction times and lowest solvent consumption of HE

Powerful and perfect for multitasking

The UniversalExtractor E-800 is perfectly suited to any demanding extraction task. Six distinct extraction positions enable individual process control and simultaneous operation of different extraction methods. High-speed heaters combined with sophisticated process control allow for the fastest and most reproducible extraction processes.


  • Multitasking
    • Six distinct extraction positions enable individual process control and simultaneous operation of different extraction methods
    • Multiple work packages can be executed in parallel
    • Faster method development and higher sample throughput
  • Analyte protection sensor
    • Patent pending analyte protection always guarantees that only a minimum level of solvent in the beaker can be found, which results in best analyte recoveries
    • Prevents the deterioration and degradation of heat sensitive analytes during all process steps
    • Ensures safe and reproducible concentration of the extract
  • Fully inert conditions and maximized safety for the analyte
    • All components in the UniversalExtractor E-800 that are in contact with the sample and the solvents are made of completely inert material
    • Eliminates sample contamination and any memory effects from leaching materials
    • The inert gas supply, selectable at all process steps (extraction, rinsing, drying) protects the analyte against oxidation
    • Inert gas is automatically switched on if the analyte protection sensor is triggered
  • Flexible applications
    • Profit from five different extraction methods in one universal glass assembly. Choose the optimal extraction method to achieve best recoveries and low result variation
    • For low contaminated samples, the Large Sample Volume (LSV) glass assembly can expand the sample volume used to the extraction by 60 %
    • Fast and equal heating, even for high boiling solvents such as water or toluene
