Description
Hoffmann pinchcock 70 mm is a laboratory hose clamp intended for controlled restriction and temporary closure of flexible tubing. The body is made of brass with a nickel-plated finish and is fitted with a flap, giving a secure mechanical pinch on soft laboratory hoses without the need for tools. At 70 mm overall size and a net weight of 0,150 kg, the clamp offers a solid, durable feel for everyday bench work in chemistry, biology and analytical laboratories. It is well suited to titration lines, temporary flow interruption, sampling setups and general fluid-path management where quick open–close action is required. Nickel plating supports corrosion resistance under typical laboratory conditions, while the Hoffmann-style geometry remains familiar to technicians who routinely handle tubing clamps. This pinchcock from manufacturer Usbeck is supplied as a single piece and fits naturally into collections of hose clamps and tubing accessories used across teaching, research and quality-control environments. Robust metal construction supports repeated use on standard flexible tubing without complex fittings.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Tubing Clamp Hoffmann 70 mm
What is this article?
Tubing Clamp Hoffmann 70 mm is the article on this page. Luminix Health distributes Usbeck for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, 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.
