Optimum SmoothFlow pistons feature unique channels that prevent air entrapment while providing a smooth profile radius to reduce fluid shear.

Nordson pistons fit perfectly inside Optimum syringe barrels to ensure uniform dispensing force to provide accurate, consistent fluid deposits and prevent dripping and oozing between shots.

Precision wiping edges clean the syringe interior as fluid is filled into or dispensed from the barrel, eliminating waste, residue, and air entrapment.

Optimum syringe barrel pistons are manufactured in EFD’s own certified silicone-free facilities in the United States and are certified for industrial use.

Standard Pistons

Precision molded from high-density polyethylene* in six unique styles, Optimum pistons ensure precise control for virtually any fluid in any application, including:

■ White SmoothFlow (General Purpose) - For use with most fluids.
■ Red SmoothFlow (Tight Fit) - For use with mechanical dispensing equipment.
■ Beige SmoothFlow (Loose Fit) - Loose-fitting pistons are used with air-entrapped fluids.
■ Orange Flatwall - Flat-walled pistons have a looser fit to prevent “bouncing” when dispensing stringy, air-entrapped fluids.
■ Blue LV Barrier - LV Barrier pistons are used with cyanoacrylates and very low viscosity fluids. ■ Clear Flex - Flex pistons are flexible and reduce “bouncing” in viscous fluids while maintaining excellent wall-wiping. *Clear Flex pistons are molded from low-density polyethylene
