Description
Screw pinchcock, Hoffmann type, B=50 mm, heavy-duty design is a durable laboratory hose clamp engineered for secure and adjustable flow control in flexible tubing systems. Crafted from nickel-plated brass, this Hoffmann-style screw pinchcock delivers reliable performance in demanding laboratory environments. With a width of 50 mm and a weight of 118,0 g, its heavy-duty construction ensures longevity and stability during frequent use with various hose diameters. The precision screw mechanism enables fine control over the pinching force, allowing users to regulate or completely stop the flow of liquids or gases as required. This clamp is well-suited for applications in analytical chemistry, life sciences and general laboratory workflows where robust, corrosion-resistant tubing clamps are essential. Available from manufacturer Bochem, the nickel-plated finish provides good resistance to chemical exposure and simplifies cleaning. Packaged as one piece, it integrates easily into standard lab setups. The heavy-duty version is particularly useful for thicker-walled tubing or situations demanding higher clamping force and durability in both research and routine laboratory operations.

Questions about Pinch cock type HOFFMANN, W=50mm, heavy, type
What is this article?
Pinch cock type HOFFMANN, W=50mm, heavy, type is the article on this page. Luminix Health distributes Bochem 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.
Which category should I open next?
