Silicone tubing

Start with the inner diameter: it must fit snugly over the hose barb or connector, usually equal to or slightly smaller than the barb, so the tube seals without a clamp at low pressure. The outer diameter follows from the wall thickness, and a thicker wall keeps the tube from collapsing under vacuum or bursting under pressure. Both are in the product title, as with the silicone tubing, translucent, 8 × 12 mm, 5 m. Barbs and connectors are in hose connectors, adapters and fittings.

Silicone is very flexible, stays soft over a wide temperature range and suits aqueous and biological media; whether it can be autoclaved is stated on each product page. It is less suitable for many organic solvents and for high pressure. PVC is transparent and economical for water and air. PTFE resists almost all chemicals but is stiff. Rubber is robust for vacuum and general lab use. Compare these options in PVC, PTFE and other tubing. For a typical silicone choice, see the silicone hose, 12 × 2 mm.

Buy by the metre when you need a few short lengths, for a single set-up or a repair, such as the silicone tubing, 8 mm ID × 10 mm OD, per metre. Buy a roll, for example 5 or 25 m, when you replace tubing regularly, use it on peristaltic pumps or equip several workstations, such as the silicone hose, 12 × 16 mm, 25 m. A roll keeps the same batch and dimensions for all your set-ups. Store tubing dark and dust-free. Questions? Ask sales@luminixhealth.com.

Silicone is widely used in peristaltic pumps because it is flexible and recovers its shape after each roller pass. Use a specific tube on a pump only when its product page says it is suitable for pumping, because ordinary silicone hose can wear quickly under the rollers. The inner diameter and wall thickness must match the pump head exactly; the head's product page states which tubing it accepts. Pumps and heads are in peristaltic and dosing pumps. Check the tube regularly and replace it before it flattens or cracks. Send us your pump model: sales@luminixhealth.com.

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.
