Description
Silicone stopper 32 - 26 mm Ø, 30 mm h is a tapered laboratory stopper made of silicone, designed for secure closure of glassware and vessels with matching neck openings. The conical profile measures 32 mm at the upper diameter, tapering to 26 mm at the lower diameter, with an overall height of 30 mm, allowing reliable insertion and a tight seal in standard laboratory flasks and bottles. Silicone construction provides the flexibility and resilience expected of modern laboratory stoppers used in chemistry, biology and analytical workflows. Supplied as a single piece, this stopper belongs to the established group of silicone stoppers that complement cork, rubber and cellulose alternatives for routine sealing tasks. The item from manufacturer Hecht is suited to everyday laboratory practice where a soft, reusable plug is required to retain liquids or vapours under normal working conditions. Its tapered geometry facilitates easy fitting and removal while maintaining consistent contact with the vessel wall. This format supports temporary or semi-permanent closures without ground-joint connections and integrates readily into standard lab glassware sets.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Silicone stoppers mm 32 - 26 Ø 30 h
What is this article?
Silicone stoppers mm 32 - 26 Ø 30 h is the article on this page. Luminix Health distributes Hecht 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.
