Description
KT3-500 Kjeltabs catalyst tablets are ready-to-use tablets formulated with 3,5 g potassium sulfate (K2SO4) and 0,4 g copper sulfate (CuSO4) for Kjeldahl digestion. The defined tablet composition supplies both the boiling-point elevator and the copper catalyst required for efficient mineralisation of organic nitrogen in sulfuric acid. By delivering a fixed salt and catalyst charge per sample, the tablets simplify preparation, limit weighing errors and support consistent digestion conditions from run to run. Supplied in a pack of 500 pieces, KT3-500 is suited to high-throughput nitrogen and protein determination in food, feed, agricultural and environmental laboratories. The tablets are compatible with standard Kjeldahl block digesters and classical wet-chemical nitrogen apparatus. Manufactured by Behr, this catalyst tablet format streamlines routine sample work-up and helps laboratories maintain reproducible digestion protocols without preparing bulk catalyst mixtures. Ideal where copper-catalysed Kjeldahl methods are specified and a convenient pre-dosed tablet is preferred.

Questions about KT3-500
What is this article?
KT3-500 is the article on this page. Luminix Health distributes Behr for laboratory use. It sits in Reagents for analysis (Ph. Eur., ASTM, DIN), inside Analytical standards & reference materials, in Produits chimiques.
A reagent for analysis is a chemical whose impurities are limited so they do not become a signal in a titration, a digestion or a photometric method. Pharmacopoeia, ASTM and DIN names point at different limit lists. The grade, not only the identity, is the purchase.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is Reagents for analysis (Ph. Eur., ASTM, DIN). The catalogue is Produits chimiques.
