Bottom Filling of All Materials
1. Insert the piston in the syringe barrel and push it down until it is flush with
the bottom of the barrel.
2. Control the flow rate of the material to prevent trapping air bubbles at the
barrel shoulder and at the piston wiper. If bubbles are being trapped, the
flow rate is probably too fast.
3. Apply steady pressure on the piston to maintain full engagement with the
material during fill.
NOTES:
• If the material pressure is too high, material can leak past the piston
wiper.
• If the material pressure is too low, the piston may float on the rising
material, increasing the possibility of trapped air bubbles under the
piston.
• If either of the above occurs, press down on the piston until it fully
engages with the material.
4. Install the tip cap.
