Optimum Syringe Barrels Pistons
Optimum® SmoothFlow™ pistons feature unique channels that prevent air entrapment while providing a smooth profile radius to reduce fluid shear.
Overview
Our 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
Specialty Pistons
In addition to our standard offering, Nordson EFD offers the following specialty pistons.
Optimum ECO
Eco-friendly pistons for use exclusively with Optimum ECO syringe barrels. They feature sustainably-sourced polyethylene to help reduce the carbon footprint.
Optimum Class VI
Manufactured from United States Pharmacopeia (USP) Class VI resin. They feature enhanced biocompatibility for medical applications.
Better Quality
Nordson EFD adheres to highly controlled manufacturing procedures, maintenance schedules, and quality specifications in the production of Optimum components.
Our dispensing components are stored in anti-static bags to protect against contamination. Package labels include lot numbers for complete process control and traceability.
