Description
Screw clamp type HOFFMANN, B=40 mm is a laboratory hose clamp engineered for reliable tubing control in scientific and technical environments. Constructed from nickel-plated brass and fitted with a flap, this Hoffmann-style screw clamp delivers adjustable compression for flexible hoses used in fluid handling. The 40 mm width suits common laboratory tubing diameters, allowing precise regulation or complete shut-off of liquid and gas lines. Weighing 49,0 g, the compact unit remains easy to position and operate by hand while providing durable clamping force. Offered as a single piece from manufacturer Bochem, it serves applications in chemistry, biology and process setups where quick hose fixation is required. The corrosion-resistant finish supports repeated use with aqueous solutions and many organic media. Its straightforward screw mechanism enables tool-free installation and removal, streamlining apparatus changes on the bench. Ideal for research, teaching and quality-control laboratories, the clamp integrates cleanly into crowded experimental assemblies and maintains consistent performance over extended service.

Questions about Pinch cock type HOFFMANN, W=40mm
What is this article?
Pinch cock type HOFFMANN, W=40mm is the article on this page. Luminix Health distributes Bochem 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.
