Description
neoChoice membrane check valve with 2 different hose olives is a compact nylon component for unidirectional flow control of hydraulic fluid, air and water. The membrane design opens fully at a differential pressure of 5-8 mbar, providing low cracking pressure suitable for sensitive laboratory circuits. It is frequently employed as a silencer or sound damper for mini vacuum pumps, reducing noise while protecting the system from reverse flow. Two different hose olives allow connection to tubing of varying diameters, offering installation flexibility. Available as a single piece from manufacturer neolab - Labor, this check valve integrates easily into vacuum lines, pneumatic setups and liquid-transfer apparatus. Its nylon construction ensures chemical compatibility with common laboratory media and supports reliable one-way operation in research, analytical and process environments where backflow prevention or quiet vacuum performance is required.

Questions about Clapet anti-retour à membrane neoChoice avec 2 olives de tuyau différentes
What is this article?
Clapet anti-retour à membrane neoChoice avec 2 olives de tuyau différentes is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Robinets & vannes, inside Tubes, tuyaux et raccords, in Matériel de laboratoire.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
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.
