Beschrijving
Hot extraction attachment according to Böhm 250 ml is a glass laboratory component designed for hot extraction procedures. The assembly is specified for a 250 ml flask with ground joint NS 29/32 and a condenser joint NS 45/40, enabling secure connection within standard extraction setups. It supports continuous solvent reflux and sample extraction workflows commonly used in analytical and preparative chemistry. With a net weight of 0,71 kg, the attachment is suitable for stable mounting on compatible glassware trains. Manufactured by Witeg, the unit is intended for laboratory environments performing solid–liquid extractions where controlled heating and efficient condensation are required. The defined joint sizes facilitate interchangeability with matching flasks and condensers, helping laboratories maintain consistent apparatus configurations. This 250 ml version is appropriate for medium-scale extractions in research, quality control and teaching laboratories that rely on classical hot-extraction techniques. The clear joint specifications simplify selection and integration into existing glassware systems without additional adapters in many standard setups.
This article is part of Soxhlet & extraction apparatus, in Distillation & extraction glassware.

Questions about JACKETED EXTRACTORS, BÖHM, 250 ML FLASK
What is this article?
JACKETED EXTRACTORS, BÖHM, 250 ML FLASK is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Soxhlet & extraction apparatus, inside Distillation & extraction glassware, in Labmateriaal.
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.
