The Fiber Analyzer FD6800 is an advanced automated instrument specifically engineered for the precise measurement of various fiber types in a wide array of plant product samples. Employing the chemical solvent extraction method, this device features an intuitive user interface with a display screen to enhance user interaction. It is capable of processing up to 36 samples concurrently. The instrument excels in quantifying numerous fiber constituents, including crude fiber (CF), acid detergent fiber (ADF), neutral detergent fiber (NDF), cellulose, and lignin. This technology is extensively utilized in the analysis of feeds, grains, seeds, food products, and other plant materials.

- Automatic solvent treatment: automatic solvent filling, constant temperature heating, cooking, shock, waste liquid discharge, and other operations.
- Filter bag technology: suitable for CF, NDF, and ADF fiber analysis methods, improve the accuracy of the determination.
- Built-in test mode: CF, NDF, ADF test mode, easy to use different test methods.
- User-defined test scheme: easy to test different samples, increase the applicability of the instrument.
- Special treatment reaction cylinder: resistant to high temperature, high pressure, and chemical corrosion, integrated mixing method cooking, improved reliability.
- Lack of liquid alarm function: automatic alarm and stop operation when the solvent is less, increasing safety.
- Wireless control: can connect to a PC for operation.
- Remote monitoring: Remote monitoring operator is optional.
- High-quality material tray: The filter bag tray is made of high-quality material, has good corrosion resistance, and is durable!
- Data printing: One-click printing of experimental results is convenient and fast.
