VELP FIWE Raw Fiber Extractors

VELP FIWE Raw Fiber 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 (according to Weende)
  • Neutral detergent fiber and acid detergent fiber determination (NDF and ADF according to Van Soest)
  • Acid detergent lignin determination (ADL according to Van Soest)
  • Different fractions of fiber (cellulose, hemicellulose, and pectin)

Raw fiber determination is useful for nutritional, economic, and legislative aspects. FIWE performs single or sequential extractions including boiling, rinsing, and filtration.

Key Features

  • Total raw fiber extraction using Weende technique
  • Rapid analysis – 2 hours vs 6 hours with manual systems
  • Reliable results
  • High reproducibility
  • Back-pressure pump prevents clogging of crucibles
  • Neutral & acid detergent fiber with NDF, ADF, Van Soest Extractions
  • Acid Detergent lignin extraction with ADL & Van Soest methods
  • Fiber fraction analysis (cellulose, hemicellulose, & pectin)
  • Links boiling, rinsing, and filtration
  • Sigle or multiple samples can be processed
  • Reagent preheating on RC 2 hotplate (provided)
  • Same crucibles used for weighing, drying, & washing – no loss
