Description
Extension for stopper tubing with an inner diameter of 2,79 mm and an outer diameter of 4,49 mm provides a defined hose section for laboratory liquid-handling and stopper-tubing assemblies. The product is offered as a 10 m unit quantity, giving sufficient length for cutting custom runs between stoppers, connectors, pumps, and vessels. These bore and outer dimensions support medium-narrow tubing paths where a stable inner lumen of 2,79 mm and an outer envelope of 4,49 mm are needed for fit and flow continuity. The 10 m pack has a stated weight of 0,126 kg, which keeps handling and storage straightforward on the bench or in consumables stock. Positioned among hoses and accessories for liquid handling and hoses for peristaltic pumps, the extension is suited to building or adapting tubing lines in routine lab workflows. Manufactured by Saint-Gobain, this extension for stopper tubing supplies clear geometric data so users can match it to compatible stopper tubing systems. Inner Ø 2,79 mm and outer Ø 4,49 mm, together with the continuous 10 m length, make it a practical choice when extending or replacing sections in existing laboratory tubing setups without redesigning the full fluid path.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Extension for stopper tubing, Inner Ø 2.79 mm, outer Ø 4.49 mm, 10 m
What is this article?
Extension for stopper tubing, Inner Ø 2.79 mm, outer Ø 4.49 mm, 10 m is the article on this page. Luminix Health distributes Saint-Gobain 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.
