Description
Blank cap KF DN 16, single is a sealing component for laboratory vacuum systems based on the KF flange standard. Manufactured from borosilicate glass 3.3, this blanking cap closes unused KF DN 16 ports on Schlenk lines, manifolds and related apparatus, maintaining vacuum integrity or inert atmosphere. Supplied as a single piece with a net weight of 0,013 kg, it is intended for modular glassware assemblies in synthetic chemistry. The blank cap from manufacturer Rettberg offers a simple, chemically resistant termination for quick-flange connections commonly found in research environments. Thermal stability and inertness of borosilicate glass 3.3 support reliable performance during air-sensitive operations and controlled-atmosphere work. Classified as an adapter-type accessory, the cap enables flexible configuration of Schlenk flasks and vacuum trains by securely blanking open ports. Its compact form facilitates easy installation and removal whenever temporary sealing of a KF DN 16 interface is required.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Dummy cap flange DN 16, single
What is this article?
Dummy cap flange DN 16, single is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
