Description
Rubber stopper, solid, featuring a top diameter of 10 mm, a bottom diameter of 6 mm and a length of 20 mm serves as a practical tapered closure for small laboratory vessels and tubing. The solid rubber form creates a snug seal that supports containment of samples, solvents or intermediate reaction mixtures during everyday lab workflows. The 20 mm length keeps the plug compact while the taper from 10 mm to 6 mm aids insertion into correspondingly sized necks and openings. This single-piece stopper from manufacturer Witeg is made of rubber and is suited to general chemical, analytical and educational laboratory practice. Solid construction without internal voids simplifies handling and visual inspection. Net weight is 0,001 kg, so the component remains light on balances and portable setups. Common uses include closing test tubes, small flasks and sample bottles for short-term storage, transfer between workstations, or protection against dust and evaporation under standard laboratory ambient conditions.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Plug Ø top 10mm Ø bottom 6mm length 20mm
What is this article?
Plug Ø top 10mm Ø bottom 6mm length 20mm is the article on this page. Luminix Health distributes Witeg 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.
