Filling the Syringe Barrel
Caution: 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.
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.
• First, vacuum adjustment is less sensitive.
• Second, the piston prevents fumes from the fluid being exhausted into the work environment.
• Third, the piston prevents fluid backflow into the dispenser if the syringe barrel is inadvertently turned upside
down.
• Fourth, 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 / 55 / 70cc sizes. If you are dispensing an RTV silicone and find that the piston bounces and causes stringing,
request EFD’s assistance in selecting a suitable piston.
Remember
For best results, EFD strongly recommends the
use of a piston as part of your dispensing system.
Do not tip the barrel
upside down or lay
flat. This will cause the
liquid to run into the
dispenser.
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.
