Description
Screw clamp type HOFFMANN B=25 mm is a compact hose clamp engineered for reliable flow regulation of flexible laboratory tubing. Constructed from nickel-plated brass and fitted with a flap, the clamp provides firm, adjustable compression without damaging the hose wall. Its mass is 25,0 g, making it light enough for repeated handling yet robust for continuous bench use. Supplied as a single unit with both net and gross weight of 0,03 kg, the clamp originates from Pakistan and is manufactured by Bochem. Typical applications include temporary shut-off or fine control of liquid and gas lines in chemistry, biology and analytical setups. The HOFFMANN design allows quick attachment and release, supporting efficient workflow changes. Dimensions corresponding to the 25 mm width ensure compatibility with common tubing diameters used in laboratory fluid handling systems.
This article is part of PVC, PTFE & other tubing, in Tubing, hoses & fittings.

Questions about Pinch cock type HOFFMANN, W=25mm
What is this article?
Pinch cock type HOFFMANN, W=25mm 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.
