Description
Silicone stopper with top diameter 46 mm, bottom diameter 38,1 mm and height 25,4 mm provides a tapered elastomeric seal for laboratory glassware and vessels. Brown silicone construction gives a flexible yet stable plug that seats cleanly in matching neck openings, supporting routine closure of flasks, bottles and similar containers. Temperature resistance from −70 °C to 200 °C allows use in cold-room conditions as well as with moderately warmed equipment without loss of sealing behaviour. Packaged as 10 pieces from manufacturer Labbox, the set is practical for stocking general chemistry, sample handling and educational benches. Net weight per pack is 0,078 kg. The conical profile—wider at the top, narrower at the bottom—simplifies insertion and removal while maintaining contact along the neck wall. These plastic laboratory stoppers offer a reusable alternative where cork or conventional rubber is less suitable, and the clearly stated metric dimensions help match the stopper to the vessel mouth. Specify this 46 mm / 38,1 mm size when that taper corresponds to your apparatus for consistent everyday sealing performance.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Silicone stopper, solid, Øtop 46mm, Øbottom 38,1 mm, h 25,4 mm, 10 pcs
What is this article?
Silicone stopper, solid, Øtop 46mm, Øbottom 38,1 mm, h 25,4 mm, 10 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.
