Description
Working connection with olive Ø 12 mm and KF DN 16, single is a precision glass adapter for Schlenk-line and vacuum-manifold systems. Manufactured from borosilicate glass 3.3, the component combines a 12 mm glass olive with a KF DN 16 flange interface, allowing rapid attachment of tubing or vessels to existing Schlenk apparatus. The single-piece design ensures a leak-tight transition between olive and clamp-style KF connections while maintaining chemical inertness and thermal stability. Compact and lightweight (net weight 0,020 kg), it serves as a spare or expansion part for custom inert-atmosphere setups. This adapter from manufacturer Rettberg integrates seamlessly with standard laboratory vacuum lines, cold traps and reaction flasks. Ideal for air-sensitive synthesis, solvent transfer and gas-handling workflows, the borosilicate construction provides long service life under repeated thermal cycling and exposure to common organic solvents and reagents used in modern synthetic chemistry laboratories.

Questions about Connection, flange DN 16 to hose connection Ø 12 mm, single
What is this article?
Connection, flange DN 16 to hose connection Ø 12 mm, single is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
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.
