Beschreibung
Pouring spout NS 14,4/23 for flasks and bottles is a laboratory accessory intended for controlled liquid transfer from flasks, bottles and volumetric flasks. The NS 14,4/23 joint size matches corresponding standard ground joints on common laboratory vessels, supporting directed pouring during routine sample handling and preparation. Designed for clean dispensing from flasks, bottles and measuring flasks, it helps keep transfer neat when working with reagent containers and volumetric glassware in everyday lab practice. Offered as a single-piece unit, the spout is practical for workflows that require repeated pouring from NS-compatible vessels without unnecessary spillage or awkward handling. This pouring aid from manufacturer Starke suits research, teaching and analytical environments where flasks and bottles with NS 14,4/23 joints are in regular use. It belongs among general laboratory materials used alongside volumetric flasks and storage bottles whenever reliable, straightforward liquid discharge is needed at the bench.

Questions about Spout NS 14,4/23 for flasks and bottles
What is this article?
Spout NS 14,4/23 for flasks and bottles is the article on this page. Luminix Health distributes Starke for laboratory use. It sits in Tubing accessories, inside Tubing, hoses & fittings, in Laborbedarf.
Tubing accessories are the clips, clamps, connectors and hangers that finish a line. A pinch clamp is how a silicone line is shut without a stopcock. The accessory has to fit the outside diameter, not the bore.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
