Description
Rubber stopper without bore 92 x 79 x 65 mm is a solid rubber laboratory stopper intended for full sealing of flasks, bottles and other laboratory containers. Constructed from rubber and supplied without a bore, it ensures a continuous, airtight closure in applications where no tubing or probes are required. The dimensional series 92 × 79 × 65 mm provides a tapered profile that seats securely in matching vessel necks, combining elasticity with a stable fit under ordinary laboratory conditions. This unbored stopper is suited to chemical, analytical and general laboratory workflows that demand reliable temporary or longer-term sealing of glassware. Supplied as a single piece from manufacturer Hecht, it belongs to the standard range of rubber laboratory stoppers used for routine handling and storage tasks. The solid rubber construction supports repeated use while maintaining seal performance. It constitutes a practical consumable for laboratories needing a larger bore-free rubber stopper in the stated size for everyday sealing duties.

Questions about Rubber stoppers without bore Ø mm H 92 x 79 x 65
What is this article?
Rubber stoppers without bore Ø mm H 92 x 79 x 65 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.
