Fibre: FibreBag is an innovative filtration method from C. Gerhardt for determining the crude fibre, ADF, NDF and ADL fractions in feedstuffs. It avoids common problems in the classic filtration method using frits and filter beds, simplifies handling and digestion of the samples and ensures better and more reliable analysis results. In the FibreBag method, digestion and filtration are carried out in a large filter bag made of a high-precision special textile that standardises the filtration conditions so that they are reproducible.


FIBRETHERM ® automates time-consuming, personnel-intensive digestion and filtration processes for determining various fibre fractions in feedstuffs. The analysis complies  with the standard methods specified by Weender and van Soest.

FIBRETHERM® enables simultaneous processing of 12 samples. Compared to the standard manual method, this represents a major reduction in the energy and chemical consumption and the time taken. The device automatically controls and monitors all the boiling, washing and filtration processes within a self-contained system.
