Avoid air in the syringe barrel

Air in the fluid is a critical issue with the Ultra 2800 Dispensing System. It can create problems with

inconsistent deposits and drooling. For best results, use an EFD barrel filling station (see below), or

bottom fill the syringe barrel. Simply insert the red piston and push it all the way inside the barrel,

flush to the dispense tip. Then fill through the tip, pushing the piston down as the fluid enters. This

prevents air from entering the syringe barrel.

If needed, eliminate air in the syringe barrel by using centrifuge or a vacuum chamber.

If the fluid being dispensed is pourable, attach an orange tip cap to the syringe barrel and pour the

fluid in. Insert the piston and carefully press it down until it contacts the fluid. The syringe barrel is

now ready for use.

If the fluid is thick or non-leveling, it

can be spooned into the barrel with a

spatula. Or, if the fluid comes packed

in a 1/10 gallon cartridge, the barrel

can be loaded with a caulking gun.

After loading, press in the piston to

move the fluid to the bottom of the

barrel and to remove trapped air.

Caution: Do not completely fill syringe

barrels. The optimum fill is a

maximum 2/3 of the barrel capacity.

If you are working with assembly fluids

with a short pot life, you may want to

fill to 1/2 of the syringe barrel.

EFD offers productive, air-free

alternatives to traditional barrel loading methods. Here are a few suggestions that can help keep the

work area clean, save time and reduce the chance of entrapped air in the fluid.

1. The EFD #8000BF Series automatic syringe filler provides consistent filling for all types of

nonpourable assembly fluids. It features built-in flow controls to prevent spillage and air

entrapment.

2. If you receive frozen epoxies or other fluids in medical type syringes with a manual plunger,

request the EFD luer-to-luer fitting #2160 to transfer the material from the original syringe to

the EFD syringe barrel.

3. Another option is the EFD #920BL barrel loader. Pack the fluid into the 12-ounce cartridge.

Place the pre-filled cartridge into the barrel loader. Using air pressure, the barrel loader fills the

syringe barrel (with piston) from the bottom up.

4. If the fluid comes prepackaged in a 1/10 gallon (300 ml) caulking type cartridge, use the EFD

#940BL barrel loader.

For additional assistance please contact an EFD Fluid Application Specialist.
