Tip Recommendations
Examples:
For tiny dots of low viscosity fluids, use a very small
diameter tip.
If the fluid is reactive to metal, use a plastic tip.
To avoid scratching or puncturing the surface,
use a flexible plastic tip.
If you have any questions, please ask.
We have many years of experience with all kinds of fluids.

Filling Syringe Barrels
If your fluid is thick or non-leveling, you can spoon it into the barrel with a spatula.
Or, if the fluid comes packed in a 1/10 gallon cartridge, try loading the barrel with a
caulking gun. Then press in the SmoothFlow piston to move the fluid to the bottom
of the barrel and to remove trapped air.
If the fluid you are dispensing is pourable, take the barrel, twist on the tip cap, and
pour in your fluid. Insert the SmoothFlow piston. Carefully press the piston down
until it contacts the fluid. The barrel is now ready for use.
Note: The correct fill is a maximum 2/3 of the barrel capacity.
(Volume measurements for EFD barrels are at the 2/3 full level.)
Do not completely fill barrels.
