Beschrijving
Hoffmann pinchcock 50 mm is a compact laboratory tubing clamp used to regulate or interrupt flow in flexible hoses during chemical, biological and general laboratory work. The 50 mm format suits common tubing diameters on benches, manifolds and temporary setups where quick, tool-free control is needed. Constructed from brass with a nickel-plated finish and fitted with a flap, the clamp provides a durable, corrosion-resistant mechanism for repeated open–close cycles. Its Hoffmann-style design allows progressive pinching of the tube wall so flow can be throttled or fully stopped without disconnecting lines. With a net weight of 0,062 kg, the unit remains light enough for frequent repositioning yet solid enough for stable clamping on the workbench. This pinchcock from manufacturer Usbeck is supplied as a single piece and fits typical hose-clamp and tubing-control applications in teaching labs, research facilities and production support areas. It supports safe handling of liquids and gases in flexible tubing by offering reliable mechanical shut-off when valves are impractical or unavailable.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Tubing Clamp Hoffmann 50 mm
What is this article?
Tubing Clamp Hoffmann 50 mm is the article on this page. Luminix Health distributes Usbeck for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labmateriaal.
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.
