SN-25 Phosphor Bronze Dispensing Needle — Incure Sniper™

Incure Sniper™ SN-25 is a high-viscosity gauge for fine-pitch bond work — 0.437 mm ID for filled epoxies, thermally conductive pastes, silver-filled conductive adhesives, and high-solid-content UV formulations where the S23's 0.564 mm bore produces a bead too wide for compact bond pads. At 23% narrower than the SN-23, the S25 handles the same high-viscosity material range and delivers sub-millimetre dot accuracy without the extreme backpressure of the S27 or S30 gauges. Non-magnetic phosphor bronze construction eliminates ferrous contamination; the white PP Luer Lock hub fits any standard dispensing barrel.

Tighter Bead Than the SN-23 — Fine-Pitch Accuracy at High Viscosity

At 0.437 mm ID — 23% narrower than the SN-23 — the S25 deposits a smaller, more precise bead from the same high-viscosity filled formulations. Where the S23 overfills compact bond pads on fine-pitch PCB joints, SMT underfill pockets, or sub-millimetre dot work, the S25 delivers controlled volume without stepping into the extreme backpressure of the S27 or S30. The result is accurate dot and bead geometry on high-viscosity materials at standard dispensing air pressures.

Non-Magnetic Phosphor Bronze — No Ferrous Contamination on Sensitive Assemblies

Steel dispensing needles shed ferrous particles that contaminate magnetic sensors, HDD read/write assemblies, and precision optical alignment components. The SN-25 is machined from phosphor bronze — non-magnetic, non-ferrous, and chemically inert to filled epoxies, conductive adhesives, cyanoacrylates, and the solvents used in electronics and medical device manufacturing. No magnetic particle sweep is required between dispensing operations.

PP Luer Lock Hub — Fits Any Standard 1cc to 30cc Dispensing Barrel

The white polypropylene Luer Lock hub seats directly on any standard 1cc to 30cc dispensing barrel — no adapters, no proprietary connectors, no tools required. White is the industry-standard colour code for this bore size; it allows immediate gauge identification during line changeovers when multiple Sniper™ gauges are in use, without reading a label or measuring the tip.

The SN-25 is the fine-pitch high-viscosity gauge in the Incure Sniper™ range. For broader high-viscosity bead work, see SN-23 (0.564 mm ID). For microdispensing of very high viscosity materials, see SN-27 (0.335 mm ID) or SN-30 (0.234 mm ID). For medium-viscosity materials (1,000–10,000 cP), see SN-21 (0.610 mm ID) or SN-20 (0.681 mm ID). For low-viscosity materials (<1,000 cP), see SN-19 (0.859 mm ID) or SN-18 (1.039 mm ID). All Sniper™ needles are phosphor bronze with PP Luer Lock hub and are available in No Coating, Electroless Nickel, or Nickel PTFE across the full range.
