Description
Blind stopper is a practical laboratory closure accessory supplied as a set of two pieces for sealing unused ports and openings. These stoppers, also referred to as Blindstopfen, provide a simple and effective means of closing off connections on apparatus, vessels or modular systems during experiments and sample handling. The pack features a net weight of 0,008 kg and a gross weight of 0,017 kg, making the components lightweight and easy to store or transport within the laboratory. Manufactured by IKA, the blind stoppers are intended for everyday use in research, quality-control and educational settings where temporary or permanent sealing of fittings is required. They help maintain system integrity, reduce contamination risk at open ports and support flexible reconfiguration of laboratory setups. Ideal as spare parts or routine consumables, the pair ensures that essential sealing elements remain readily available. Their compact form suits a wide range of standard laboratory environments and workflows.

Questions about stopper (2 pcs.), Stopper
What is this article?
stopper (2 pcs.), Stopper is the article on this page. Luminix Health distributes IKA 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.
