Description
Rubber stopper with top diameter 14 mm, bottom diameter 11 mm and height 18,5 mm is a tapered laboratory plug manufactured from red natural rubber. It is designed to close flasks, bottles and similar glassware necks in routine chemical, biological and educational laboratory settings. The cone tapers from 14 mm at the top to 11 mm at the bottom across a height of 18,5 mm, providing a secure friction seal for medium-small openings. Supplied as a pack of 25 pieces with a net weight of 0,080 kg, the unit is practical for equipping multiple workstations or replenishing shared stocks. These stoppers from manufacturer Labbox use red natural rubber, valued for its elasticity and suitability as a soft, compressible closure material. They form part of the classic rubber-stopper assortment used together with cork, silicone and cellulose stoppers for everyday vessel sealing tasks. Uniform dimensions across the pack help achieve consistent seating on matching necks. The intermediate size and multi-piece packaging suit laboratories that require a reliable supply of natural-rubber stoppers for general experimental work, sample holding and teaching demonstrations without additional coatings or sterile claims.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Rubber stopper, solid, Øtop. 14 mm, Øbottom 11 mm, h 18,5 mm, 25 pcs
What is this article?
Rubber stopper, solid, Øtop. 14 mm, Øbottom 11 mm, h 18,5 mm, 25 pcs is the article on this page. Luminix Health distributes Labbox 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.
