Description
Solid rubber stopper with upper diameter 92 mm, lower diameter 79 mm and length 65 mm is a large tapered laboratory stopper for sealing wide-neck glassware and vessels. It is made of rubber in a solid, unbored form, giving a closed seal without openings for tubing or probes. The conical geometry tapers from an upper diameter of 92 mm to a lower diameter of 79 mm over a length of 65 mm, enabling a firm seat in matching larger openings. Offered as one piece with a net weight of 0,388 kg, it is intended for routine laboratory sealing where a substantial rubber closure is required. This stopper from manufacturer Witeg supports general chemical, preparative and educational work with flasks or bottles of corresponding neck size. Solid construction suits temporary or longer sealing of contents under normal bench handling. Clearly stated upper and lower diameters plus length aid correct size selection. The rubber material combines flexibility with durability for repeated insertion and removal by hand.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Plug O-Ø 92mm U-Ø 79mm L: 65mm
What is this article?
Plug O-Ø 92mm U-Ø 79mm L: 65mm is the article on this page. Luminix Health distributes Witeg 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.
