Description
Flex-tube, PFA is a flexible laboratory hose intended for general liquid handling, featuring a connection inner diameter of 16 mm and an outer diameter of 18 mm. The PFA construction offers chemical inertness together with the flexibility needed for bench-top and apparatus connections when transferring aqueous solutions and many laboratory solvents. Each unit is supplied as a 1 m length with a weight of 1,380 kg, giving a practical segment for installation, replacement, or temporary routing without excess bulk. The defined 16/18 mm geometry matches common hose fittings in this size range and supports reliable coupling with clamps and connectors. From manufacturer ROTH SELECTION, this flex-tube sits in the hoses-and-accessories category for everyday lab use and is suited to media transfer, flexible line routing, and general-purpose fluid paths where a chemically resistant PFA tube is preferred. Smooth internal surfaces help maintain flow and simplify rinsing between experiments or process steps.
This article is part of PVC, PTFE & other tubing, in Tubing, hoses & fittings.

Questions about Flex-tube, PFA, connection inner-Ø 16 mm, outer-Ø 18 mm, 1 m
What is this article?
Flex-tube, PFA, connection inner-Ø 16 mm, outer-Ø 18 mm, 1 m is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in PVC, PTFE & other tubing, inside Tubing, hoses & fittings, in Labware.
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.
