Description
PharMed® BPT-stopper hoses provide laboratory-grade tubing for liquid handling on peristaltic pumps. This variant has an inner diameter of 2,79 mm and an outer diameter of 4,49 mm, offering a larger bore than smaller stopper hose sizes while remaining suitable for precise stopper-style pump connections. The pack comprises 6 pc(s) with a combined weight of 0,031 kg, so it is easy to store and issue for routine work. These hoses are intended for controlled transfer, dosing and continuous fluid movement in research and analytical environments where dimensional consistency at the pump head matters. From manufacturer Saint-Gobain, PharMed® BPT-stopper hoses form part of the hoses and accessories category for laboratory liquid handling and are commonly chosen for peristaltic pump setups that need a defined inner and outer diameter. The stated geometry helps match tubing to existing pump heads and stopper arrangements without guesswork. Integrate them as dedicated stopper hose components in standard labware configurations that rely on reliable, compact tubing for everyday liquid-handling tasks.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about PharMed® BPT-stopper hoses, Ø inner 2.79 mm, Ø outer 4.49 mm, 6 unit(s)
What is this article?
PharMed® BPT-stopper hoses, Ø inner 2.79 mm, Ø outer 4.49 mm, 6 unit(s) 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.
