Description
Extractor 250 ml for specifically light liquids with socket NS 45/40 is a laboratory glassware component intended for extraction work with liquids of low specific gravity. It is manufactured from borosilicate glass 3.3 and supplied complete with insert. The upper connection is a socket joint NS 45/40 while the lower cone joint is NS 29/32, allowing integration into standard ground-joint assemblies. A lateral PTFE valve adjustable from 0 to 3 mm enables controlled flow during operation. This extractor from manufacturer Rettberg is delivered as a single piece with a net weight of 0,580 kg. The design supports modular extraction apparatus configurations commonly used in analytical and preparative laboratories. Borosilicate glass 3.3 provides the chemical resistance and thermal stability required for routine solvent handling. Standardised joints ensure reliable sealing and interchangeability with complementary glassware. The unit is suited to procedures where specifically light liquids must be processed under controlled conditions within extraction setups.
This article is part of Soxhlet & extraction apparatus, in Distillation & extraction glassware.

Questions about Extractor, 250 ml, for specific light liquids, socket size 45/40,
What is this article?
Extractor, 250 ml, for specific light liquids, socket size 45/40, is the article on this page. Luminix Health distributes Rettberg 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.
