Needles with Smaller, Smoother Outer Diameters
With an advanced spool-to-spool continuous coating process that makes it possible to achieve uniquely thin, smooth, and consistent coatings, Merit needle components combine larger inside diameters for optimal flow rates with smaller, smoother outer diameters for less painful insertions. These components are available in a wide range of diameters and base materials, including stainless steel and Nitinol. We offer a complete range of coating options, including PTFE coatings that can provide electrical insulation for low voltage applications. </p
Benefits of the Coated Needles
- Wide range of OD/ID
- Smooth surface
- Ultra-thin, well-defined coating
- Extremely consistent diameter
- Tight coating tolerance (2.5 µm – 5.0 µm)
- Cost-effective coating process
- Ability to apply coatings up to 20 µm per side for insulation purposes
