Description
Stoppers made of silicone rubber with a 4 mm hole diameter are laboratory plugs sized 17 x 22 x 25 mm for sealing and connecting work with vessels and related labware. The silicone rubber construction and defined hole opening support use as plugs in everyday laboratory glass, vessel and consumable setups where a flexible stopper with a central passage is required. Each pack contains 25 pc(s) and has a total weight of 0,195 kg, making the unit convenient for stocking benches, preparation areas and shared consumable stores. Dimensions of 17 x 22 x 25 mm together with the 4 mm hole give a clear size reference when matching stoppers to necks, tubes or apparatus openings. These stoppers from manufacturer ROTH SELECTION sit within the stoppers and clamps range for laboratory glass, vessels and consumables and are intended as straightforward plug components rather than specialised fittings. They suit routine sealing, temporary closures and simple through-hole arrangements in general laboratory practice. Pack presentation as 25 pc(s) supports consistent replenishment without over-ordering single pieces. Specify hole diameter and outer dimensions when selecting the matching size for your glassware or tubing layout.

Questions about Stoppers made of silicone rubber, Ø Hole 4 mm, 17 x 22 x 25 mm, 25 unit(s)
What is this article?
Stoppers made of silicone rubber, Ø Hole 4 mm, 17 x 22 x 25 mm, 25 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.
