Description
Kjeldahl tablets ST are ready-to-use catalyst tablets formulated for nitrogen determination according to the Kjeldahl method. Each tablet weighs 3,5 g and is intended for analytical digestion of food and related sample matrices. The tablets exhibit a density in the range 2,5 to 2,9 g/cm³ and a boiling point of 1689 °C, reflecting the high-temperature stability required during sulphuric-acid digestion. Supplied as 250 units in a plastic pack, the format supports efficient routine throughput in food-analysis and quality-control laboratories. These tablets streamline catalyst addition, improve reproducibility of digestion conditions and reduce weighing steps compared with loose salt mixtures. Material from manufacturer Carl ROTH fits established Kjeldahl workflows for protein and total-nitrogen assays. The compact tablet presentation helps maintain consistent catalyst loading across multiple digests while keeping laboratory handling straightforward for daily analytical use.

Questions about Kjeldahl tablets ST, Tablet 3,5 g, 250 unit(s), plastic
What is this article?
Kjeldahl tablets ST, Tablet 3,5 g, 250 unit(s), plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Soxhlet & extraction apparatus, inside Distillation & extraction glassware, in Labware.
A Soxhlet extractor washes a solid with clean hot solvent over and over: the chamber fills, siphons, and fills again. The extractor, the flask and the condenser are sized together. The thimble holds the solid. Extractor size is given as the siphon volume.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
