Kjeltabs

Salt and a catalyst are used to speed up the reaction in Kjeldahl digestions. As a convenient way to obtain the correct dosage for proper boiling conditions, Tecator supplies Kjeltabs - tablets containing potassium sulphate and a catalyst (selenium, titanium or copper).

Kjeltabs are supplied in two sizes; one or more tablets are added per tube, to obtain an optimal salt/acid ratio. The smaller 1.5 g size is recommended for the 100 ml tubes.
