Syringe Barrel Pistons

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

Precision wiping edges clean the syringe interior as fluid is dispensed, eliminating waste and residue.

Our pistons fit perfectly inside Optimum syringe barrels to ensure uniform dispensing force and prevent dripping and oozing between shots. These components work as a system to provide accurate, consistent fluid deposits.

Precision molded 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.
