Description
Connecting piece for tubing in straight form without stopcock and with cone NS 14/23 is a laboratory glass adapter for linking flexible tubing to ground-joint apparatus. Manufactured from heat-resistant, durable borosilicate glass, the piece is fitted with a straight hose adapter that accepts tubing of 6 to 10 mm diameter. Excellent grinding quality at the NS 14/23 cone prevents air and liquid leakage, ensuring a tight seal during vacuum or liquid transfer work. This connector from ISOLAB Laborgeräte keeps the flow path linear and free of valves, simplifying setups where an unobstructed connection is preferred. The straight form integrates cleanly into standard laboratory glassware trains and supports reliable hose attachment across common tubing sizes. Supplied as a single piece with a net weight of 0,0584 kg, the adapter is suited to everyday laboratory fluid-handling tasks that demand thermal durability, leak-free ground joints and a straightforward hose interface without an integrated stopcock.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about adapters - with nozzle - straight - without stopcock - cone : NS 14/23
What is this article?
adapters - with nozzle - straight - without stopcock - cone : NS 14/23 is the article on this page. Luminix Health distributes ISOLAB for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Matériel de laboratoire.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
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.
