Description
Stoppers made of silicone rubber with a 6 mm hole diameter offer a flexible sealing option for laboratory vessels and glassware. Measuring 29 x 35 x 30 mm, these tapered plugs are sized for openings that require a slightly larger body while retaining a 6 mm central bore for tubing or probe passage. The silicone rubber material supplies the elasticity needed for reliable seating and repeated handling in daily lab practice. Supplied in packs of 10 pc(s) with a total weight of 0,266 kg, the set is convenient for stocking as a standard consumable among stoppers and plugs. These stoppers from manufacturer ROTH SELECTION support general laboratory glass, vessel and apparatus work where bored elastomer closures are preferred over solid plugs. Typical use includes temporary sealing during sample preparation, storage or simple experimental setups that need continuous access through the stopper hole. Clear dimensional specification and multipack format help laboratories match the stopper to compatible necks and maintain consistent inventory for teaching, research and routine analytical environments.

Questions about Stoppers made of silicone rubber, Ø Hole 6 mm, 29 x 35 x 30 mm, 10 unit(s)
What is this article?
Stoppers made of silicone rubber, Ø Hole 6 mm, 29 x 35 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 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.
