Description
Pouring spout NS 19/26 for flasks and bottles is a laboratory accessory for directed liquid transfer from flasks and bottles fitted with matching ground joints. The NS 19/26 joint size aligns with standard laboratory glassware of the same designation, enabling practical pouring during sample handling, reagent dispensing and everyday bench work. Supplied as one piece, this spout supports clean discharge when liquids must be transferred from flasks or bottles without awkward tilting or uncontrolled flow. It is suited to research, teaching and analytical settings where NS 19/26 joints are common on storage and reaction vessels. The pouring spout from manufacturer Starke forms part of standard laboratory pouring accessories used with flasks and bottles. It helps streamline liquid handling steps whenever a dedicated spout is preferred for NS 19/26 openings, keeping transfer straightforward in routine laboratory workflows involving flasks and bottles of this joint size.

Questions about Spout NS 19/26 for flasks and bottles
What is this article?
Spout NS 19/26 for flasks and bottles is the article on this page. Luminix Health distributes Starke for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
