Description
Screw clamp type HOFFMANN, B=17 mm is a precision laboratory hose clamp engineered for controlled restriction of flexible tubing in analytical and research setups. Fabricated from nickel-plated brass and fitted with an integrated flap, the Hoffmann-style design delivers secure, adjustable compression without damaging hose walls. The 17 mm B dimension accommodates a practical range of common laboratory tubing diameters, while the compact 21,0 g construction keeps the unit lightweight yet robust. Supplied as a single piece, this clamp from manufacturer Bochem supports reliable flow regulation of liquids or gases in chemical, biochemical and quality-control workflows. The nickel plating improves surface durability and corrosion resistance under routine laboratory conditions. Easy screw adjustment enables fine control of flow rates, and the flap assists rapid positioning on the hose. Suitable for temporary shut-off, metering or isolation tasks on benches, in fume hoods or within apparatus assemblies, the clamp offers dependable mechanical performance for everyday laboratory tubing management.

Questions about Pinch cock type HOFFMANN, W=17mm
What is this article?
Pinch cock type HOFFMANN, W=17mm 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.
