Description
Extractor 250 ml for specifically heavy liquids with socket NS 45/40 is a versatile laboratory glass apparatus engineered for extraction work with high-density liquids. Constructed from borosilicate glass 3.3 and supplied complete with insert, the unit features a cone joint NS 29/32 and a side-mounted PTFE valve adjustable between 0 - 3 mm. The intermediate 250 ml capacity balances sample throughput with manageable solvent volumes, making it suitable for both analytical and small preparative extractions. The NS 45/40 socket ensures secure mating with standard ground-joint components in multi-part assemblies. Offered by manufacturer Rettberg, this extractor leverages the excellent resistance of borosilicate glass 3.3 to thermal shock and chemical attack. It is particularly appropriate for laboratories performing liquid-liquid extractions of specifically heavy phases, including configurations related to Soxhlet apparatus. Accurate joint geometry and the integrated PTFE valve facilitate precise flow control, easy assembly and efficient cleaning between successive extraction cycles.
This article is part of Soxhlet & extraction apparatus, in Distillation & extraction glassware.

Questions about Extractor, 250 ml, for specific heavy liquids, socket size 45/40,
What is this article?
Extractor, 250 ml, for specific heavy 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.
