Description
Complete liquid-liquid extraction apparatus 250 ml comprises an extractor body NS 45/40, matching insert with cone NS 45/40 and sleeve NS 29/32, a jacketed condenser of 250 mm length with two NS 29/32 joints, and a 500 ml round-bottom flask with NS 29/32 joint. The assembly includes a hollow NS compact stopcock for controlled solvent handling and is configured for liquid-liquid extraction workflows. This ready-to-use set from manufacturer Witeg enables continuous partitioning of analytes between immiscible phases in organic synthesis, natural-product isolation and sample clean-up. The standardised ground-glass joints ensure leak-free connections and straightforward interchange of components. Supplied as one complete unit, the apparatus supports efficient laboratory extraction protocols without the need for separate sourcing of individual parts. Its robust glass construction withstands typical thermal and chemical conditions encountered during reflux and solvent cycling, making it suitable for both research and routine analytical environments focused on liquid-liquid separation techniques.
This article is part of Soxhlet & extraction apparatus, in Distillation & extraction glassware.

Questions about Extraction apparatus 250 ml, liquid-li.
What is this article?
Extraction apparatus 250 ml, liquid-li. is the article on this page. Luminix Health distributes Witeg 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.
