Description
Screw clamp type Hoffmann, nickel-plated, B=12 mm is a precision laboratory tubing clamp intended for controlled restriction of flexible hoses. Manufactured from nickel-plated brass and fitted with a flap, the clamp has a width of 12 mm and weighs 19,0 g, combining corrosion resistance with a compact, easy-to-handle form. The Hoffmann screw mechanism permits gradual, reproducible adjustment of flow rate, making it ideal for fine regulation during chromatography, perfusion, titration or continuous reagent delivery. Its nickel-plated surface resists common laboratory chemicals and repeated cleaning cycles. Available as a single piece from manufacturer Bochem, this screw clamp is well suited to chemistry, life-science and analytical workstations where stable, vibration-resistant hose control is essential. The modest size allows installation in confined apparatus or multi-line manifolds without adding bulk, supporting organised and reliable fluid handling across research, teaching and routine quality-control environments that depend on flexible tubing systems.
This article is part of PVC, PTFE & other tubing, in Tubing, hoses & fittings.

Questions about Pinch cock type HOFFMANN, W=12mm
What is this article?
Pinch cock type HOFFMANN, W=12mm 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.
Which category should I open next?
