Optimum® Syringe Barrels – High-Precision Fluid Dispensing with ZeroDraft™ Technology

Optimum® syringe barrels are engineered for accurate, repeatable fluid dispensing with virtually zero waste. Featuring ZeroDraft™ walls and consistent internal diameters, these barrels maintain a perfect seal with pistons for smooth, turbulence-free filling and dispensing.

Why Choose Optimum Syringe Barrels?

• ZeroDraft™ Design: Eliminates trapped air for faster, cleaner fills.
• Multiple Sizes: Available in 3cc, 5cc, 10cc, 30cc, 55cc, and 70cc capacities.
• Durable & Compatible: Made from a proprietary polypropylene blend for clarity and chemical resistance.
• Industrial-Grade Quality: Manufactured in certified silicone-free facilities in the USA.

Amber Syringe Barrels

For UV-sensitive fluids, amber barrels block UV and visible light wavelengths while allowing fluid level visibility. Available in all sizes.

Applications

• Electronics assembly: underfill, potting, conformal coating.
• Precision dispensing for adhesives, sealants, and lubricants.
• High-volume production: 70cc barrels reduce downtime by minimizing fluid changeovers.

Key Features

• Designed using Computational Fluid Dynamics for optimal flow and repeatability.
• Packaged in anti-static bags to prevent contamination.
• Lot-numbered labels for process control and traceability.

Frequently Asked Questions

Can I reuse a syringe barrel for my assembly fluid?
Syringe barrels are designed for single use only. Attempting to clean and reuse them can leave residue of the original fluid or the cleaning materials, compromising the assembly fluid. Also, the cleaning process, and even the dispensing process, can change the surface structure of the syringe barrels. As a result of these factors, EFD cannot guarantee the quality or performance after first use.

EFD syringe barrels are not just built but also priced for one-time use. The costs of scrap and rework, not to mention unscheduled downtime, are much higher. Once your syringe is empty, throw it away and get a new one.

Are EFD syringe barrels compatible with other manufacturers pistons?
EFD’s pistons are designed specifically for EFD syringe barrels. We have spent decades perfecting our process and establishing a robust supply chain to ensure quality products with consistent dimensions.

No industry standards exist to codify syringe barrel pistons and syringe barrels in terms of diameters, etc. As a result, no reliable interoperability exists. Although syringe barrels and syringe barrel pistons from other manufacturers might appear compatible with those from EFD, we would not recommend using them due to limitations in consistency, and compatibility along the full length of the barrel.

How to store filled syringes for easy removal of air bubbles?
Always store syringes vertically, with the luer end facing down. This allows air pockets to migrate upward. Next, remove accumulated air using the following steps:

1. Store filled syringe barrels vertically, right side up.
2. Before use, squeeze the sides of the barrel and push the piston down to purge the air.
