Raw Fibre Extractor
FIWE RAW FIBER EXTRACTOR
The FIWE 3 and FIWE 6 extractors are suitable for raw fiber determination, conventionally known as an indigestible residue. Rapid analysis, reliable results and high reproducibility are some of the most relevant benefits of these units which are ideal for the following applications:
- total raw fiber determination (Weende)
- neutral detergent fiber and acid detergent fiber determination (NDF and ADF, Van Soest) acid detergent lignin determination (ADL, Van Soest)
- different fractions of fiber (cellulose, hemi-cellulose and pectin)
- Raw fiber determination is useful for nutritional, economic and legislative aspects. FIWE performs single or sequential extraction including boiling, rinsing and filtration.
In order to perform a reliable raw fiber determination test, the sample must have a low fat content (<1%). For those samples that exceed this value, preliminary fat extraction is required using acetone, hexane or petroleum. The COEX performs rapid fat extraction directly in the same glass crucibles that are used by the FIWE 3 and FIWE 6. A great benefit as the user can start raw fiber extraction immediately after completing fat extraction.
