Description
Tube end plug, plastic, black is a finishing component for laboratory stand and frame systems, designed to close open tube ends cleanly and securely. Made from polypropylene (PP), the plug combines light weight with robust everyday durability and is finished in black for a neat, uniform appearance on support structures. With a net weight of 0,030 kg and supplied as a single piece, it is easy to stock and fit during assembly or maintenance of scaffolding, retort stands and modular frameworks. The polypropylene body helps protect tube openings from dust ingress and minor mechanical damage while giving assemblies a tidy termination. This end plug from manufacturer Rettberg is intended for use with tubular laboratory stands and related support hardware, where reliable closure of free ends improves both safety and presentation of the workstation. Suitable for general laboratory, teaching and technical environments that rely on modular tube-based stands, it supports organised setups for clamps, holders and apparatus without adding unnecessary bulk or complexity to the frame.

Questions about Tube plug, black plastic
What is this article?
Tube plug, black plastic is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
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.
