Description
Pouring spout NS 19/26 with standard ground joint cone is a laboratory glass accessory for controlled liquid transfer from flasks and sulfonation flasks. The NS 19/26 cone engages matching sockets, allowing directed pouring that limits drips and improves handling safety during product work-up or reagent addition. Suitable for organic synthesis, preparative chemistry and general laboratory use, it integrates into standard European ground-joint glassware assemblies. The component is supplied as one piece from manufacturer Witeg and is intended for repeated bench use alongside round-bottom flasks and related adapters. With a net weight of approximately 0,01 kg it remains light and easy to store yet robust enough for daily transfer tasks. This pouring spout complements existing jointed glassware sets in research, teaching and quality-control environments where clean, controlled dispensing from ground-joint vessels is essential. It belongs to the pour-spout category and supports efficient workflow when transferring solvents, reaction mixtures or isolated products between vessels.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Pourer ST 19/26
What is this article?
Pourer ST 19/26 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
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.
