Optimum Syringe Barrel Pistons
Optimum® SmoothFlow™ pistons feature unique channels that prevent air entrapment while providing a smooth profile radius to reduce fluid shear.
Standard Pistons
A piston is inserted into the syringe barrel after it has been loaded with fluid to ensure uniform dispensing, prevent dripping, and eliminate waste by wiping barrel walls clean as fluid is dispensed. Optimum pistons are molded from high-density polyethylene.*
- White SmoothFlow (General Purpose): For use with most fluids.
- Beige SmoothFlow (Loose Fit): Loose-fitting pistons are used with air-entrapped fluids.
- Red SmoothFlow (Tight Fit): For use with mechanical dispensing equipment.
- 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.
