Hydrolysis Unit

 

Velp HU6 Hydrolyis Unit, 6 Place
 
The Velp HU6 Hydrolysis Unit is the ideal and safe solution for hydrolysis:
-        Hydrolysis, filtration and washing of the sample in the same unit
-        Simultaneous hydrolysis of six samples with minimum manual handling
-        Glass crucible is designed for use directly in the SER 148 Solvent Extractor Units
 
In the large majority of food and feed products the fats contained are chemically bonded with other components. For the determination of the total fat content of these samples, preliminary hydrolysis using hydrochloric acid (or ammonium hydroxide in some cases), followed by filtration and washing in a glass crucible, is indispensible in order to free the fat molecules ready for extraction.
This procedure is required in a number of AOAC Official Methods to determine the fat content of food samples such as meat, cheese, seafood, chocolate, cereal flours, etc.
The Velp Hydrolysis Unit HU6 is the ideal solution for the acid and basic hydrolysis of food and feed samples prior to solvent extraction. The HU6 performs hydrolysis in complete safety and handles six samples at a time in order to maximise productivity.
 
The samples are heated in test tubes in an aluminium heating block offering excellent thermal homogeneity. The hydrolysed sample is then filtered in a glass crucible and washed with warm deionised water to eliminate traces of hydrochloric acid used.
The HU6 is supplied with a vacuum pump which reduces the filtration time and offers improved operator safety thanks to the reduction of acid fumes.
The glass crucible containing the hydrolysed and washed sample is oven dried before being placed in a desiccator. The crucible is then transferred directly to the SER 148 Solvent Extraction Unit avoiding any possible sample loss and ensuring improved accuracy of results.
Applications:
The HU6 works in conjunction with the SER 148 according to Official Procedures providing highly accurate and precise results for fat content determination.
Acid digestion:
-        nuts (peanuts, walnuts, etc.)
-        seeds (sunflower, soy, etc.)
-        meat and meat products
-        fishery products and derivatives
-        cocoa and derivatives
-        eggs
-        cereal flours
-        bread and baked products (bread sticks, crackers, croissants, etc.)
-        pasta
-        animal feed
Basic digestion:
-        powder milk, concentrated milk and cheese which have a high lactose content (fresh cheese, mozzarella, etc.)
 
The HU6 is supplied complete with 1 box of Celite, 1 Kg. and 1 box of glass sand, 2 kg.
The HU6 must be integrated with the following glassware kit (A00000085), necessary to perform the hydrolysis of 3 samples. Every kit (A00000085) includes: 3 x P1 crucibles, 3 x test tubes (42 mm. dia. x 300mm. long, 250ml.), 3 x 45 mm. dia. covers, 1 x suction manifold, 1 x vacuum pump, 6 x gaskets, 3 x perforated plugs, 3 x suction pipes and 3 x crucible holders.
NOTE: For the simultaneous analysis of 6 samples, 2 glassware kits (A00000085) are necessary.
