Description
Stoppers made of silicone rubber with a 6 mm hole diameter are practical laboratory plugs for sealing vessels, flasks and related glassware in routine workflows. Each stopper measures 26 x 32 x 30 mm and is intended for secure seating in compatible openings where a flexible elastomer closure is required. The central 6 mm bore allows tubing, probes or simple access lines to pass through while the silicone body maintains the seal around the vessel neck. Packaged as 10 pc(s) with a pack weight of 0,212 kg, the set supports everyday consumable use across general laboratory glass and vessel applications. These stoppers from manufacturer ROTH SELECTION belong to the labware category of stoppers, clamps and plugs and suit temporary or semi-permanent closure tasks during sample handling, storage or simple apparatus assembly. Silicone rubber construction provides the elasticity needed for repeated insertion and removal without rigid fittings. Dimensions, hole size and multipack format make the product straightforward to stock for teaching labs, research benches and quality-control environments that rely on bored silicone plugs for flexible vessel sealing.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Stoppers made of silicone rubber, Ø Hole 6 mm, 26 x 32 x 30 mm, 10 unit(s)
What is this article?
Stoppers made of silicone rubber, Ø Hole 6 mm, 26 x 32 x 30 mm, 10 unit(s) is the article on this page. Luminix Health distributes Carl Roth 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.
