Description
Kjeldahl tablets CK are specialised catalyst tablets for nitrogen determination according to the Kjeldahl method, widely used in food analysis and related analytical chemistry. Each tablet weighs 3,9 g and has a density of 2,7 g/cm³, supporting reproducible catalyst dosing during the digestion step of sample preparation. This pack provides 250 units in plastic packaging, giving laboratories a convenient pre-portioned format that reduces weighing effort and helps standardise routine series of digestions. The tablets are intended for total nitrogen or protein assays on foodstuffs and other matrices processed under classical Kjeldahl protocols. Available from manufacturer Carl ROTH, the product is assigned UN number 3077 for transport classification. Consistent tablet mass supports method control in quality laboratories where operator-to-operator variation must be kept low. Analytical teams working on nutritional labelling, food composition testing or research programmes that rely on wet-chemical nitrogen determination can integrate these tablets into established digestion workflows. The practical pack size and clearly stated physical data assist inventory planning and method documentation for laboratories that perform Kjeldahl analyses on a regular basis.

Questions about Kjeldahl tablets CK, Tablet 3,9 g, 250 unit(s), plastic
What is this article?
Kjeldahl tablets CK, Tablet 3,9 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.
