Beschrijving
Blank-off flange in aluminium for DN 25 KF is a laboratory vacuum accessory designed to seal unused ports on KF small-flange systems. The aluminium blank closes a DN 25 KF interface when that connection is not in active use, aiding configuration, service, and safe isolation of vacuum apparatus. Delivered as a single piece, it matches standardised KF geometry found on laboratory pumps, manifolds, and instrument vacuum ports. From manufacturer WELCH, the blank-off flange is classified among accessories and spare parts for laboratory equipment. Aluminium offers a practical material choice for everyday KF blanking applications in professional laboratory settings. Facilities running KF-compatible vacuum hardware can apply the DN 25 KF blank-off flange wherever an open small-flange port needs a secure closure. Clear product identification by material and nominal KF size simplifies selection against existing DN 25 KF connections in the laboratory inventory.

Questions about Blank-Off Flange, Aluminium, DN 25 KF
What is this article?
Blank-Off Flange, Aluminium, DN 25 KF is the article on this page. Luminix Health distributes WELCH for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labmateriaal.
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.
