Beschreibung
Blank-off flange, fixed, stainless steel, DN 40 CF is a terminating flange for ConFlat vacuum connections on laboratory apparatus. It provides a fixed stainless-steel blank-off for DN 40 CF ports that must be closed during installation, modification, or routine service. The unit is supplied as 1 pc and functions as an accessory or spare part for systems built around the CF flange standard at DN 40. Fixed blank-off flanges in stainless steel are commonly used to seal unused chamber ports, manifold branches, and instrument interfaces while maintaining material compatibility with surrounding CF hardware. This DN 40 CF blank-off flange comes from manufacturer WELCH and is intended for laboratories that need a defined ConFlat termination rather than an improvised cover. The DN 40 designation sets the nominal size, and the CF marking identifies the flange geometry so the part can be matched to suitable copper gaskets, fasteners, and mating flanges. Listed among accessories and spare parts for laboratory equipment, it supports clear port management on vacuum lines and vessels. Choose this fixed stainless-steel blank-off flange when a DN 40 CF closure is specified and a single-piece laboratory spare is required.

Blank-Off Flange, Fixed, Stainless Steel, DN 40 CF is the article on this page. Luminix Health distributes WELCH for laboratory use. It sits in Other instruments & spare parts, in Präzisionsinstrumente.
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.
