Description
KF Flange Weld Stub, Borosilicate Glass 3.3, 80 mm, DN 25 KF is a glass vacuum accessory for laboratory vacuum lines and apparatus. The component is made from borosilicate glass 3.3 and provides an 80 mm weld stub terminated with a DN 25 KF small-flange interface for quick-release vacuum fittings. It enables glass systems to be joined to standardized KF connections used on pumps, traps, manifolds, and instrumentation. Supplied as one piece per pack, the weld stub serves as a build part or replacement element when custom glass vacuum assemblies are prepared or maintained. Manufacturer WELCH supplies this format for laboratory equipment accessory and spare-part use alongside vacuum apparatus. Borosilicate glass 3.3 is selected for the thermal and chemical resistance expected in general laboratory glass service. The DN 25 KF geometry defines the mechanical interface for planning seals, clamps, and mating flanges, while the 80 mm length supports practical welding or glassblowing into existing tubing. This KF flange weld stub is intended for non-sterile laboratory vacuum construction and routine equipment upkeep where a glass-to-KF transition is required.

What is this article?
KF Flange Weld Stub, Borosilicat Glass 3.3, 80mm, DN 25 KF 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.
