Filling the Syringe Barrel
Barrel Filling Techniques
Do not completely fill syringe barrels. The optimum fill is a maximum 2/3 of the barrel capacity and 1/2 of the barrel
capacity when using the EFD blue LV Barrier piston.
CAUTION
For best results, we strongly recommend that you use a piston as part of your dispensing system. The white EFD
SmoothFlow piston is appropriate for most fluids and has several advantages:
• Vacuum adjustment is less sensitive.
• The piston prevents fumes from the fluid being exhausted into the work environment.
• The piston prevents fluid from flowing back into the dispenser if the syringe barrel is inadvertently turned upside
down.
• The piston makes it easy and safe to change tips without dripping. For watery solvents and cyanoacrylates,
request the blue EFD LV Barrier piston, available in 3cc, 10cc, and 30 / 55cc sizes. Contact EFD for assistance
in selecting a suitable piston.
System Setup and Operation (continued)
Remember
For best results, EFD strongly recommends the use of a piston as part of your
dispensing system.
When changing tips
or attaching a tip cap,
snap the safety clip
completely closed to
prevent any dripping
or bubbling.

If you choose to not use a piston when dispensing thin fluids, remember these
important points.
Fumes cannot
escape.
No air gap
when using the
SmoothFlow piston.
SmoothFlow
piston prevents
fluid backflow.
Do not tip the barrel
upside down or lay
flat. This will cause
the liquid to run into
the dispenser.
