Description
Rotilabo® check valves are polypropylene one-way valves for laboratory liquid-handling lines where backflow must be limited. Moulded in natural/transparent PP and measuring 60 mm in length, they allow visual inspection of the flow path while integrating into flexible hose circuits used for media transfer, sampling, and instrument feed. The compact body suits bench-top assemblies and hose-accessory setups that need directional control without bulky hardware. Polypropylene offers chemical resistance appropriate for many aqueous solutions and mild laboratory solvents encountered in research and routine work. Each pack contains 5 pc(s) and weighs 0,031 kg, making the valves practical for stocking multiple workstations or shared liquid-handling kits. These Rotilabo® check valves from manufacturer ROTH SELECTION support hose-connector workflows across labware and fluid-routing applications. Install them in-line wherever unidirectional flow helps protect upstream components, stabilise transfer lines, or prevent reverse contamination between vessels, keeping systems simple to assemble and easy to reconfigure between experiments.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Rotilabo®-check valves, PP, natural/transparent, length 60 mm, 5 unit(s)
What is this article?
Rotilabo®-check valves, PP, natural/transparent, length 60 mm, 5 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
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.
