Velp Hydrolysis Unit - HU 6

The HU 6 offers the optimum solution for the acid hydrolysis of food and feed samples prior to solvent extraction for total fat analysis.
Very often the samples to be analyzed have a high fat content and need to be prepared for fat extraction. The HU 6 is a 6-position hydrolysis unit that combines safety with performance, reducing manual handling to the minimum. Hydrolysis is carried out with hydrochloric acid for approximately one hour at a temperature of 170 °C. The hydrolyzed sample is then filtered in a glass crucible and washed with warm deionized water in order to eliminate the residues of hydrochloric acid.

The sample is now ready to be processed using the SER 148.

The HU 6 is suitable for both acid and basic hydrolysis.
