Buchi FatExtractor E-500

The FatExtractor E-500 delivers reference fat and oil determination using classical solvent extraction techniques. Six sample positions and interchangeable glass assemblies let each variant target the most appropriate extraction method — Soxhlet, Hot Extraction (Randall) or Continuous Extraction (Twisselmann) — for reproducible, official-method-compliant results. Individual level sensors, integrated solvent recovery and a compact bench footprint make the E-500 the standard tool for food, feed and dairy fat analysis.

Key specifications:

• Three extraction methods: Soxhlet, Hot Extraction (Randall), Continuous Extraction (Twisselmann)

• Six parallel sample positions for high productivity

• Standard sample glass tube: 65 mL; expanded LSV version for low-fat samples

• Individual level sensors for optimized cycle turnaround and solvent monitoring

• Integrated solvent recovery with detachable collection bottle

• Compatible with common solvents: petroleum ether, hexane, chloroform

• Modular design allows switching between extraction methods on the same platform

Available models:

• E-500 SOX — classical Soxhlet extraction

• E-500 SOX ER — Soxhlet with expanded sample range

• E-500 HE — Hot Extraction (Randall) for fast throughput
