Description
Kjeldahl tablets with Wieninger catalyst are solid catalyst tablets prepared for nitrogen determination according to the Kjeldahl method in analytical and food chemistry. Each tablet weighs 2,5 g, enabling convenient, reproducible dosing during sample digestion. Designed for the analysis of food and related materials, they support routine protein and total-nitrogen workflows that rely on the Wieninger catalyst system. These tablets from manufacturer Carl ROTH fit established digestion protocols where a defined catalyst tablet simplifies preparation and improves consistency between runs. Laboratories performing classical Kjeldahl digestion can integrate the 2,5 g tablets directly into standard heating and digestion sequences. The pack size of 250 units is practical for series analyses, method development, and quality-control environments that require a stable Wieninger-type catalyst supply.
This article is part of Soxhlet & extraction apparatus, in Distillation & extraction glassware.

Questions about Kjeldahl tablets, (Wieninger catalyst), tablet 2,5 g, 250 unit(s), plastic
What is this article?
Kjeldahl tablets, (Wieninger catalyst), tablet 2,5 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.
