Buchi UniversalExtractor E-800

The UniversalExtractor E-800 combines up to five classical solvent extraction methods on a single platform, giving laboratories full flexibility for demanding environmental, contaminant and residue analysis. Six independent extraction positions allow parallel operation of different methods, while integrated high-performance condensers and analyte-protection sensors safeguard even volatile solvents and heat-sensitive compounds. Fully inert construction eliminates contamination and memory effects, and efficient vapor capture enables operation outside a fume hood.

Key specifications:

• Five extraction methods: Soxhlet, Soxhlet warm, Hot Extraction, Continuous Flow, Twisselmann

• Six independent extraction positions with individual process control

• Sample volume: 65–130 mL standard; 220 mL Large Sample Volume (LSV) option

• Compatible with water and organic solvents with boiling points below 150 °C

• Solvent recovery greater than 90 %, even for volatile solvents

• Analyte protection sensor prevents beaker dry-out and shields heat-sensitive compounds

• Fully inert materials eliminate contamination and cross-memory effects

• Optional inert gas supply throughout the process protects against oxidation

Applications:

• Environmental analysis: contaminants in soil, sludge, sediment and waste

• Food and feed testing including fat determination and residue extraction
