VELP KjTabs for Digesters

These VELP KjTabs™ for Digesters consist of accurately pre-dosed tables composed of sulfate, to increase the boiling point of sulphuric acid, plus a metal salt such as Copper (Cu), Selenium (Se), or Titanium (Ti) for time saving. Along with catalysts there are also specific antifoaming KjTabs which are fundamental to the good outcome of the analysis since the production of foam tends to reduce the original quantity of the sample during the initial phase of the mineralization process. This can occur in many agricultural samples or fat rich products.

The addition of a suitable catalyst, along with high temperatures, influences the speed and the fficiency of mineralization in Kjeldahl analyses. Achieving the highest level of performance in a wide range of Kjeldahl applications is now possible with VELP’s genuine catalyst tablets. The use of catalysts is now recognized and officially accepted by the major standards such as AOCS, AOAC, AACC, and ISO to accelerate Kjeldahl digestion.

Choose the most effective KjTabs for your application:

VCM – Universally applicable, with a low copper content

VKPC – ideal when a high amount of copper is required

VCT – for tougher samples & even faster digestion
