Design & Handling
• Larger internal diameters provide higher potential flow, while smaller diameters support finer liquid dispensing.
• The straight blunt end is intended for dispensing and fluid-transfer applications rather than piercing.
• Select the gauge according to liquid viscosity, required flow and dispensing precision.
Technical Notes
• Confirm mechanical compatibility with the syringe, dispenser or other fluid-handling connection before use.
• Smaller internal diameters are more sensitive to clogging with viscous or particle-containing fluids.
• Verify stainless steel compatibility with the liquid, solvent, electrolyte or other process medium before use.
