Description
Pump tubing 12,7 × 3,3 mm silicone is a pharmaceutical-grade hose engineered for peristaltic pumps. Fabricated from platinum-cured silicone, it features an inner diameter of 12,7 mm, wall thickness of 3,3 mm and outer diameter of 19,3 mm. The material is odourless, non-toxic and non-haemolytic in line with USP and FDA FCR 177.2600, and is free from phthalates and peroxides. Its low-binding surface limits protein adhesion, which is advantageous for sensitive media and bioprocess fluids. The tubing can be autoclaved and sterilised by gamma irradiation or ethylene oxide, enabling controlled cleaning regimes. Shore A hardness 50 delivers the flexibility needed for repeated roller compression while preserving lumen geometry. Supplied in a 15 m length from manufacturer Landgraf HLL, this larger-bore silicone pump tubing supports higher volumetric flow in laboratory, pilot and production setups where clean, biocompatible transfer lines are essential for consistent dosing and circulation tasks.

Questions about Pump hose, 12.7*3.3 mm, silicone, 1 m
What is this article?
Pump hose, 12.7*3.3 mm, silicone, 1 m is the article on this page. Luminix Health distributes Landgraf HLL for laboratory use. It sits in Silicone tubing, inside Tubing, hoses & fittings, in Labware.
Silicone tubing stays flexible across a wide temperature range and survives repeated autoclaving, which is why peristaltic pumps and media lines use it. It is not the choice for strong solvents, which migrate into the wall.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
