Description
Rubber stopper without bore H 49 x 41 x 40 mm is a solid rubber laboratory stopper created for effective sealing of flasks, bottles and other laboratory vessels. Fabricated from rubber and free of any bore, it presents an unbroken sealing face that ensures a tight, continuous closure once inserted. The dimensions H 49 x 41 x 40 mm suit a broad selection of common neck diameters and generate a stable friction fit. Delivered as a single piece, the stopper belongs to the traditional assortment of rubber stoppers employed across chemical, analytical and educational laboratory environments. Its solid construction is well suited to tasks that demand a complete seal without openings for tubing or probes. This item from manufacturer Hecht constitutes a practical, everyday sealing component that complements standard labware inventories. It is appropriate for general laboratory organisation, sample containment and basic experimental work where a resilient rubber stopper without bore is required.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Rubber stoppers without bore Ø mm H 49 x 41 x 40
What is this article?
Rubber stoppers without bore Ø mm H 49 x 41 x 40 is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Matériel de laboratoire.
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.
