Tips for Best Results

✓ Use the shortest needle suitable for your job — with 28 GA, minimizing length is critical to maintaining adequate flow pressure
✓ Always cap needles immediately when not in use — micro-bore tips are especially susceptible to clogging
✓ Inspect before each use — replace bent or clogged needles immediately to maintain micro-precision dispensing accuracy
✓ 28 GA is best suited for very low viscosity materials only — high viscosity adhesives may cause excessive back-pressure or clogging
✓ Confirm Luer Lock or Luer Slip compatibility with your dispensing equipment before use
