Description
Silicone stopper, upper Ø 107,0 mm, lower Ø 94,0 mm, length 65 mm is a transparent, flexible laboratory stopper designed for reliable sealing of larger flasks, bottles and laboratory vessels. Made from silicone, the stopper offers elasticity and a clean surface suitable for repeated use in everyday laboratory workflows. The tapered geometry runs from an upper diameter of 107,0 mm to a lower diameter of 94,0 mm at a length of 65 mm, supporting a firm fit across matching neck openings and adequate insertion depth for stable closure. This model from manufacturer Witeg is supplied as one piece and is intended for chemistry, life-science, environmental and teaching laboratories that stock silicone stoppers among standard consumables. The transparent, flexible body conforms well to glass and allows visual inspection of the contact area. With a net weight of 0,569 kg, it is a practical choice for temporary vessel closure where a durable silicone seal is preferred to cork or conventional rubber stoppers in general laboratory applications.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Silicone plug O-Ø 107.0mm U-Ø 94.0mm length 65mm
What is this article?
Silicone plug O-Ø 107.0mm U-Ø 94.0mm length 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.
