VELP develops and produces high-quality consumables to be used in conjunction with the Kjeldahl nitrogen determination series equipment, ensuring the accuracy and reliability of the results. Including: digestive catalytic tablets, nitrogen free weighing cups, and boric acid powder.

KjTabsTM series catalytic tablet is an accurate quantitative formula of sulfate mixture, mainly used in the sample digestion process. It contains a KjTabsTM defoamer, which can prevent a lot of foam during digestion.

High viscosity or powdered samples such as syrup may have certain residues when transferred to the digestive tract after weighing. VELP nitrogen free weighing cup can be used for the above types of samples, facilitating sample transfer and reducing experimental errors.

In the distillation stage of Kjeldahl nitrogen determination, ammonia gas is collected in boric acid solution after condensation for the next step of titration and to avoid the loss of gaseous ammonia. VELP's unique VreceiverTM is a formula of accurately quantified boric acid powder and indicator, with a ratio following the AOAC method. It can quickly prepare 1 L of boric acid receiving solution for ammonia reception and colorimetric titration.
