Description
Check valve, PE-HD, for hose inner Ø 6–9 mm is a laboratory non-return valve designed to maintain one-way flow in flexible tubing lines. Manufactured from PE-HD, it connects to hoses with an inner diameter of 6–9 mm and helps prevent backflow during liquid transfer, sampling or media handling. The compact valve supports controlled fluid paths in general laboratory setups where reverse flow could contaminate upstream vessels or disrupt process sequences. Supplied in a pack of 10 pieces from manufacturer Vitlab, it is practical for equipping multiple workstations or keeping spare parts on hand. Typical use includes gravity-fed or low-pressure tubing circuits in chemistry, biology and quality-control environments that require simple directional control without complex fittings. Clear sizing for the stated hose range allows straightforward matching to existing PE or similar flexible lines, supporting reliable day-to-day fluid handling on the bench.

Questions about Non-return valve, PE-HD, for tubing inner dia. 6 - 9 mm
What is this article?
Non-return valve, PE-HD, for tubing inner dia. 6 - 9 mm is the article on this page. Luminix Health distributes Vitlab for laboratory use. It sits in HPLC accessories, inside HPLC columns & accessories, in Chromatography equipment.
HPLC accessories are the unions, the ferrules, the lamp and the mixer parts around the pump and the detector. A ferrule that has been swaged on one fitting does not reseal on another. The part has to be the one for that thread and that tubing.
An HPLC column is a tube packed, or coated, with a stationary phase. The sample is carried through it by a liquid, and the compounds leave at different times. The phase, the particle size, the length and the internal diameter decide the separation. A guard column is a short sacrificial piece in front of the analytical column. Fittings and tubing have a bore that either preserves the peak or smears it. Compound names follow IUPAC. Data are on PubChem. Method grades often cite the European Pharmacopoeia or USP.
