PVC, PTFE & other tubing

PVC is flexible, transparent and economical for water, cooling lines and many aqueous solutions, for example the PVC tubing, 7 mm inner, 10 mm outer diameter. Silicone stays flexible over a wide temperature range and is common for pumps and autoclavable lines. PTFE and FEP are the most chemically inert and suit aggressive solvents and sampling lines, such as the PTFE tube, 5 mm inner diameter, 5 m. For vacuum, use thick-walled rubber tubing, like the rubber vacuum tubing, 8 × 16 mm. Check resistance to your specific chemical on the product sheet or ask us: sales@luminixhealth.com.

The inner diameter is what must fit: it slides over the hose barb or connector, so it should match the barb's outer diameter or be slightly smaller. Titles give inner × outer diameter, or inner diameter × wall thickness, so read them carefully: the rubber vacuum tubing, 8 × 16 mm has an 8 mm bore and a thick wall. Wall thickness decides whether tubing holds vacuum without collapsing and how much pressure it takes. The outer diameter matters for clamps and push-in fittings. Matching connectors are in hose connectors, adapters and fittings.

PVC is the flexible everyday tube for water and mild aqueous liquids. PTFE is the stiff, almost inert tube for solvents. Other polymers sit between them. The bore, the wall and the chemical resistance are the specification, and the tube is cut to length.

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.
