Incure Sniper™ SN-21 is the precision medium-viscosity gauge in the range — 0.610 mm ID for UV adhesives, light epoxies, and thickened cyanoacrylates in the 1,000–10,000 cP range where the SN-20's 0.681 mm bore produces a bead wider than compact bond pads allow. At 10% narrower than the SN-20, the SN-21 delivers tighter bead lines and smaller deposit volumes at the same dispense pressure, without stepping up into the backpressure of the high-viscosity gauges. Non-magnetic phosphor bronze construction eliminates ferrous contamination on sensitive assemblies; the light blue PP Luer Lock hub fits any standard dispensing barrel.
At 0.610 mm ID — 10% narrower than the SN-20's 0.681 mm — the SN-21 places the same medium-viscosity adhesives onto bond pads where the S20 overfills. For semiconductor under-fill, optical bonding on close-pitch surfaces, and micro-well deposition where precise bead width is the governing parameter, the SN-21 delivers the reduction in deposit width needed without changing the adhesive, the pressure, or the dispense speed.
Steel dispensing needles shed ferrous particles that contaminate magnetic sensors, HDD read/write assemblies, and precision optical alignment components. The SN-21 is machined from phosphor bronze — non-magnetic, non-ferrous, and chemically inert to UV adhesives, epoxies, cyanoacrylates, and the solvents used in electronics and medical device manufacturing. No magnetic particle sweep is required between dispensing operations.
The light blue polypropylene Luer Lock hub seats directly on any standard 1cc to 30cc dispensing barrel — no adapters, no proprietary connectors, no tools required. Light blue 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-21 sits within the medium-viscosity band of the Incure Sniper™ range. For wider medium-viscosity deposit, see 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). For high-viscosity adhesives and gels (>10,000 cP), see SN-23 (0.564 mm ID), SN-25 (0.437 mm ID), SN-27 (0.335 mm ID), or SN-30 (0.234 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.
