The analytical procedure for the determination of dietary fiber involves a series of digestions of the sample by thermostable enzymes using the enzymatic digester GDE. The magnetic stirrer of GDE ensures homogeneity thanks to a continuous and constant stirring of the sample while avoiding overheating that could compromise the success of enzymatic digestions. CSF6 is optimal for efficient filtration, after the samples have been processed by the Enzymatic Digester GDE. CFS6 filtration unit is able to perform single or multiple samples at the same time, up to a maximum of 6 samples at the same time, in less than 20 minutes, even at full load.
