Classical Extraction
 | Automated extraction systems for Soxhlet, hot, and continuous flow extraction covering a broad range of applications
|
BUCHI is the only provider of automated parallel extraction systems for all applications. Fat determination according to AOAC or §64 LFBG is achieved with the Hydrolysis Unit E-416 in combination with the Soxhlet E-816. Alternatively, we also offer hot extraction solutions according to Randall or Goldfisch. The B-811 is the most comprehensive approach for non-fat applications offering Soxhlet Standard, Soxhlet Warm, Hot Extraction and Continuous Flow in one instrument.
Hydrolysis Units B-411, E-416 - Access to matrix bound fat
The Hydrolysis Units B-411 and E-416 provide a safe and fast acid digestion handling for multiple samples at the same time. The acid hydrolysis is an integral part of extractions according to Weibull-Stoldt and is required in a number of AOAC Official Methods to determine fat in processed food like cheese, seafood, dressings, meat, etc.
- E-416: 6 position hydrolysis unit
- B-411: 4 position hydrolysis unit
Soxhlet and hot extraction for fat determination
The Extraction Units E-812/816 are designed for classical Food and Feed applications in real compliance with AOAC methods.They are available as fully automated real class Soxhlet systems (E-812/816 Sox) or as Hot Extraction configurations (E-812/816 HE) to perform automated hot extractions according to Randall or Goldfisch.
- E-812/816 Sox: Automated Soxhlet with 2 or 6 positions
- E-812/816 HE: Automated Hot Extraction with 2 or 6 positions
Soxhlet for non-fat applications
The Extraction System B-811 is the most convenient and versatile of all automated extraction systems offering 4 different extraction techniques in one unit. Perform a Soxhlet Standard, a Soxhlet Warm, a Hot Extraction, or Continuous Flow – each process is fully automated and controlled. Additionally: work under completely inert conditions!The instrument is available in a standard and LSV configuration for large volume samples (trace analysis).
- B-811 the most versatile extraction system
- B-811 LSV for large sample volumes (trace analysis)
