Description
Rubber stopper with top diameter 14 mm, bottom diameter 11 mm and height 18,5 mm is a tapered laboratory closure made from red natural rubber. The conical geometry supports a firm fit in glass necks, flasks, bottles and similar vessels used in routine laboratory work. Soft natural rubber provides the flexibility needed for repeated insertion and removal while maintaining contact along the sealing surface. Pack size is 25 pieces, with a net weight of 0,080 kg per pack, making the unit convenient for bench stock and teaching laboratories. These stoppers from manufacturer Labbox belong to the standard rubber-stopper range used for temporary or semi-permanent closures in chemistry, biology and general laboratory practice. Dimensions suit smaller apertures commonly found on volumetric and reaction glassware. The solid, unbored form is intended for simple sealing tasks where no tubing passage is required. Consistent taper and height help operators select the correct size quickly when matching stoppers to glassware openings. Suitable for everyday laboratory sealing needs where a natural-rubber tapered plug of defined top, bottom and height dimensions is specified.
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 Matériel de laboratoire.
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.
