Description
Blank-off flange, fixed, stainless steel, DN 100 CF is a fixed sealing component for ConFlat vacuum ports, intended to close unused openings on laboratory and process vacuum apparatus. Fabricated in stainless steel, it follows DN 100 CF flange geometry so open CF faces can be blanked directly when the mating standard is already CF. Fixed blank-off flanges of this type provide a durable metal-sealed closure that helps maintain vacuum integrity on manifolds, chambers, and instrument lines. The article is supplied as a single piece and functions as an accessory or spare part for laboratory equipment vacuum systems. This stainless steel blank-off flange from manufacturer WELCH enables reliable port blanking on DN 100 CF assemblies during installation, system changes, or temporary isolation of unused connections. Laboratory staff and vacuum system builders can mount it on compatible CF hardware to seal open flange faces and later remove the blank if the port must be restored. It is appropriate for vacuum manifolds, pump interfaces, and analytical instrument layouts that use ConFlat connections and require a clear mechanical solution for spare or idle DN 100 CF ports.

Questions about Blank-Off Flange, Fixed, Stainless Steel, DN 100 CF
What is this article?
Blank-Off Flange, Fixed, Stainless Steel, DN 100 CF 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 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.
