Description
Rubber stopper without bore 75,5 x 64,5 x 55 mm is a solid rubber laboratory stopper intended for complete sealing of flasks, bottles and other vessels. Made of rubber and supplied without any pre-drilled hole, it provides an uninterrupted closure wherever tubing, probes or glassware inserts are not required. The dimensional profile of 75,5 × 64,5 × 55 mm allows the stopper to seat securely in matching neck openings, combining flexibility with a reliable fit under typical laboratory conditions. This unbored design belongs to the standard range of laboratory stoppers used in chemical, analytical and general research workflows for temporary or longer-term sealing tasks. Offered as a single piece from manufacturer Hecht, the stopper supports everyday handling of glassware and containers in preparative and routine laboratory environments. Its solid rubber construction delivers the resilience needed for repeated insertion and removal while maintaining a tight seal. The product is a practical consumable for laboratories requiring dependable, bore-free rubber stoppers in the indicated size.

Questions about Rubber stoppers without bore Ø mm H 75,5 x 64,5 x 55
What is this article?
Rubber stoppers without bore Ø mm H 75,5 x 64,5 x 55 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.
