Syringe Barrel Pistons, EFD

About this item

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.

White SmoothFlow™ wiper pistons are used with most fluids
Beige SmoothFlow™ pistons are loose-fitting and used with air-entrapped fluids
Red SmoothFlow™ pistons are tight-fitting and used with mechanical dispensers
Orange Flat-walled pistons have a looser fit to prevent “bouncing” when dispensing stringy, air-entrapped fluids
Blue LV Barrier pistons are for cyanoacrylates and very low viscosity fluids
