Description
Solid rubber stopper with upper diameter 105 mm, lower diameter 95 mm and length 50 mm is a large tapered laboratory plug for wide-neck flasks, bottles and vessels requiring a firm friction seal. Constructed from rubber as a solid, non-bored stopper, it provides a robust mechanical closure for everyday laboratory use where a conical gum stopper of this size is specified. The taper runs from 105 mm at the top to 95 mm at the base across a 50 mm length, giving reliable seating and engagement depth in corresponding openings. Net weight is 0,584 kg per piece. This stopper from manufacturer Witeg suits routine sealing work in analytical, educational and industrial labs, including temporary closure of larger containers. It forms part of the standard rubber-stopper assortment used together with cork, silicone and cellulose stoppers when a solid rubber plug with these diameters is needed. Pack size is one piece for simple ordering and stock control.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Plug O-Ø 105mm U-Ø 95mm L: 50mm
What is this article?
Plug O-Ø 105mm U-Ø 95mm L: 50mm 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.
