Beschreibung
Parnas-Wagner apparatus for nitrogen determination is a complete macro-scale distillation unit intended for classical Kjeldahl nitrogen analysis. The set includes a 250 ml Kjeldahl flask fitted with a droplet catcher and is configured for reliable steam distillation of ammonia after sample digestion. This glass apparatus supports quantitative nitrogen determination in organic and inorganic matrices commonly encountered in food, feed, environmental and agricultural laboratories. The macro design accommodates larger sample sizes while the integrated droplet catcher minimises carry-over and improves distillate purity. Manufactured by Witeg, the complete assembly is supplied as a single ready-to-use unit with a net weight of 1,519 kg. It is suitable for teaching laboratories as well as routine analytical work where the classical Parnas-Wagner distillation method remains the reference technique for total nitrogen measurement.
This article is part of Soxhlet & extraction apparatus, in Distillation & extraction glassware.

Questions about Macro Apparatus for determination of nitrogen
What is this article?
Macro Apparatus for determination of nitrogen is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Soxhlet & extraction apparatus, inside Distillation & extraction glassware, in Laborbedarf.
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.
