Product detailed description

Vieweg All-Metal Dispensing Needle, 3 cannulas, 0.50 mm, G21, L20 mm

All-metal Vieweg dispensing needle with 3 stainless steel 1.4301 cannulas in a nickel-plated brass hub, Luer-Lock thread. The multiple cannulas apply 3 parallel dots or beads at once, speeding up dispensing on repeated positions. With no plastic parts it withstands solvents and temperature and is reusable.

A 0.50 mm (Gauge 21) bore is a proven workhorse size for solder pastes, epoxies, SMT adhesives and silicones, producing a continuous bead without breaks. The longer 20 mm cannula reaches between taller components, into grooves and around edges.

For a finer deposit choose G22 (0.40 mm) from the same range; for thicker media or higher flow choose G20 (0.60 mm). The same bore is also available with 2 cannulas. The Luer-Lock thread fits standard dispensing cartridges and syringes from 3 to 55 ml as well as dispensing valves with this connection.
