Beschrijving
Distilling column according to Snyder with 3 balls is a specialised glassware component for Kuderna-Danish sample concentrators. Manufactured from borosilicate glass and fitted with an NS 19/26 ground joint, the column supports efficient solvent evaporation and analyte concentration in analytical sample-preparation workflows. The three-ball Snyder design promotes controlled reflux and vapour–liquid contact, helping to minimise analyte loss during concentration steps. This column from manufacturer Witeg is intended for use with the corresponding Kuderna-Danish apparatus and is suitable for organic-trace and environmental laboratories performing solvent reduction prior to chromatographic or spectroscopic analysis. The robust borosilicate construction provides good thermal and chemical resistance under typical laboratory distillation conditions. Compact and precisely jointed, the column integrates directly into standard Kuderna-Danish setups, enabling reproducible concentration of extracts while maintaining the integrity of volatile or semi-volatile target compounds.

Questions about Snyder column with 3 balls for Kuderna-
What is this article?
Snyder column with 3 balls for Kuderna- is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Destillatiekoppen, adapters & kolommen, inside Destillatie- & extractieglaswerk, in Labmateriaal.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
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.
