Kjeldahl Digestion Units

The digester is a widely used instrument in laboratories performing nitrogen analysis for diversified applications in food&feed, beverage, environmental, chemical and pharmaceutical industries.

The most common nitrogen & protein determination technique
Applications in multiple markets
Food & Feed / Beverages (nitrogen, protein, Total Kjeldahl Nitrogen)
Environmental (COD, Total Kjeldahl Nitrogen)
Chemical and Pharmaceutical (organic nitrogen) industries
Conformity with multiple standards protocols
AOAC, ISO, EPA, DIN etc.
Kjeldahl analysis method
– Break down the bonds that hold the polypeptides together
– Convert them into simpler molecules such as H₂O, CO₂ and NH₃
– Reactions can be speeded up
by higher temperature used during digestion
by the presence of acid, salt and catalysts
– During the reaction corrosive, toxic gases are created
for example SO₂ and SO₃
– Gases can be neutralized using the VELP
Dedicated pump, able to aspirate gases and vapors
Scrubber to capture final traces of toxic fumes
VELP also offers consumables to speed and and simplify digestions
