Description
Blank-off flange, fixed, stainless steel, DN 250 CF is a vacuum accessory designed to close unused ports on CF flange connections in laboratory and technical vacuum systems. The fixed blank-off configuration offers a rigid, non-rotatable seal matched to the DN 250 CF nominal diameter, aligning with ConFlat-style metal-sealed flange practice. Stainless-steel construction supports use in laboratory environments that demand mechanical robustness and compatibility with high-vacuum hardware. Delivered as one piece, the flange functions as a spare or configuration element for vacuum chambers, manifolds, and pump lines. This blank-off flange from manufacturer WELCH forms part of the accessory and spare-parts offering for laboratory equipment and is defined for DN 250 CF geometry. It allows unused CF openings to be blanked cleanly during assembly, service, or system modification while preserving the fixed flange orientation. The component fits standard CF vacuum assemblies employed in analytical, process, and research laboratories that depend on durable stainless-steel flange components for reliable sealing of open ports.

What is this article?
Blank-Off Flange, Fixed, Stainless Steel, DN 250 CF is the article on this page. Luminix Health distributes WELCH for laboratory use. It sits in Other instruments & spare parts, in Lab instruments.
Some instruments do not sit cleanly in one measuring principle, and every instrument eventually needs a spare: a lamp, a fuse, a seal, a knob. The spare has to be the part for that model. A near match is a different part. Calibration of the instrument, once it measures, belongs with EURAMET, BELAC and the BIPM.
