Description
Rotilabo®-stoppers with 2 holes are grey laboratory plugs sized 17 x 22 x 25 mm for sealing medium-small vessel necks while routing tubing or glass connectors through two pre-cut openings. The tapered geometry and dual-hole layout suit common bench assemblies that need both an inlet and an outlet without modifying solid stoppers. Natural-rubber construction provides the flexibility expected for seating against glass and similar laboratory vessels during temporary closure. The pack contains 25 pc(s) and weighs 0,227 kg, supporting shared stocks in teaching labs, quality-control rooms and research groups. Offered under the Rotilabo® line from manufacturer ROTH SELECTION, these stoppers form part of the stoppers and clamps range within laboratory glassware consumables. Clear dimensional data help match the stopper to the neck opening and to the tubing diameter used in the setup. Two-hole grey stoppers of this size are practical for gas washing bottles, simple reaction vessels and transfer lines where a reproducible mechanical seal and organised cable or tube routing are required day to day.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Rotilabo®-stoppers with 2 holes, grey, 17 x 22 x 25 mm, 25 unit(s)
What is this article?
Rotilabo®-stoppers with 2 holes, grey, 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.
