Fiber Analyzers that use pre-heated reagents for fiber analysis according to Weende, Van Soest and other official methods. FIWE is a fiber analyzer suitable for raw fiber extraction, 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 extraction (Weende) - neutral detergent fiber and acid detergent fiber extraction (NDF and ADF, Van Soest) - acid detergent lignin extraction (ADL, Van Soest) - different fractions of fiber (cellulose, hemicellulose and pectin) Raw fiber analysis is useful for nutritional, economic and legislative aspects. FIWE performs single or sequential fiber extraction including boiling, rinsing and filtration. FIWE is available in different configurations: FIWE 3, a 3-position raw fiber analyzer FIWE 6, a 6-position raw fiber analyzer
