Changing the 500 µL Piston Noses

1.Remove the syringe from the pump as described page 6-4.

2.Slide the piston out of the syringe barrel.

3.Remove the piston nose from the piston rod by carefully pinching the piston nose with a pair of cutters and gently pulling the piston nose off the piston rod. Take care not to damage the end of the piston rod when removing the piston nose.

4.Remove any remaining debris of the original nose from the end of the piston rod.

5.Put the new piston nose in its recess in the piston nose holding tool.

6.Turn the tool upside down and place the piston assembly.

7.Slacken the piston button and remove it from the piston rod. Slide the clamping tool down the piston rod and press the 2 tools firmly against each other. A slight rotation of the clamping tool ensures a correct fitting.

8.Remove the tools away from the piston assembly.

9.Dip the piston nose in distilled water and slide the piston into the syringe.

10.Hold the syringe upright with the threaded end of the syringe resting on a flat, clean surface. Slide the piston into the syringe until the piston stops (the nose is level with the end of the syringe).

11.Slide the piston button against the body of the syringe and tighten the Allen screw that secures the piston button onto the piston rod.

12.Slide the piston up and down in the syringe five or six times to ensure a smooth operation be- tween the piston and syringe.

13.Make sure of the presence of the plastic cover when re-mounting the syringe on the pump as recommended below.

14.Remount the syringe on the pump as described page 6-4.
