How Does the FIWE Fiber Analyzer Work?

Q: How does the FIWE Classic crude fiber extractor work?

Sample Preparation: The sample is placed in a glass crucible.

Chemical Digestion: Sequential boiling with dilute sulfuric acid, then potassium/sodium hydroxide, isolates fiber from other sample components.

Filtration: Integrated peristaltic and air pumps provide precise filtration, keeping the residue in the crucible.

Drying and Ashing: The crucible with residue is dried and ashed externally to complete the analysis.

Result Calculation: The mass loss after ashing equals the crude fiber content.

Q: What methods does FIWE support?

Weende method: Traditional crude fiber analysis.

Neutral Detergent Fiber (NDF): Measures plant cell wall components.

Acid Detergent Fiber (ADF): Measures cellulose, lignin, and more.

Acid Detergent Lignin (ADL): For lignin determination.
