About Kjeldahl Tablets
Kjeldahl tablets (Kjeltabs) are pre-measured blends used during the digestion step of Kjeldahl nitrogen determination. Added with concentrated sulphuric acid, they raise the effective digestion temperature and accelerate oxidation, converting nitrogen to ammonium sulphate for subsequent distillation and titration. Using tablets improves handling safety and reproducibility across runs.
Contains: K2SO4; CuSO4.5H2O; Se
