We are proud to announce the release of the new Velp Hydrolysis Unit HU 6.
This unit is the right solution for acid and basic hydrolysis of food and feed samples, prior to solvent extraction using the SER148.
The HU 6 performs simultaneous hydrolysis of six samples with minimum manual handling.
The HU6 works in combination with the SER148 according to Official Procedures, providing highly accurate and precise results for fat content determination.
Decription:
The HU 6 Hydrolysis Unit is designed specifically for the preliminary hydrolysis of food samples prior to the analysis to determine the total fat content percentage. The unit houses up to 6 glass test-tubes Ø 42mm meaning that up to six samples can be hydrolyzed simultaneously. The quantity of sample required depends on the fat content of the sample itself and ranges from 3-10g.
Hydrolysis is carried out in an acid environment (hydrochloric acid 4N) or in some cases in a basic environment (ammonium 20% w/v) for approximately one hour at a temperature of 170°C. The Hydrolyzed sample is then filtered in a glass crucible and washed with warm de-ionized water to eliminate traces of Hydrochloric acid.
The dry hydrolyzed sample then undergoes extraction by solvents in the Velp SER148 3/6 in order to determine the percentage total fat content.
The HU6 offers the possibility of reproducing the exact operating conditions, ensures complete operator safety and a saving in terms of time and costs (chemical reagents).
The compact design of the instrument also saves space on the laboratory bench.
