Changing the 25 mL Piston Noses

You don’t need a special tool for mounting the piston nose on the 25 mL piston. The nose screw- fits onto the piston shaft.

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

2.Slide the piston out of the syringe barrel. It may be necessary to screw the piston securing screw back into the bottom of the piston and pull on the screw to remove the piston from the syringe barrel.

3.Hold the piston nose firmly in one hand and unscrew the nose from the piston shaft.

4.Screw a new piston nose on the shaft.

5.Slide the piston into the syringe and complete the piston nose fitting by screwing the shaft until the piston nose turns with the piston shaft.

6.Remove the piston from the syringe and dip the piston nose in distilled water and slide the piston up and down in the syringe five or six times to ensure a smooth operation between the piston and syringe.

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

Part Number Description

F4015068 1 x 25 mL piston nose.

Changing the Syringe Piston and Piston Noses

Changing the 5 mL and 10 mL Piston Noses

The piston nose mounting kits are composed of a piston nose holder and a piston shaft holder.

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

2.Slide the piston out of the syringe barrel. It may be necessary to screw the piston securing screw back into the bottom of the piston and pull on the screw to remove the piston from the syringe barrel.

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

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

Part Number Description

F4015003 5 mL piston nose mounting kit.

F4015004 10 mL piston nose mounting kit.

F4015066 1 x 5 mL piston nose and O-ring.

F4015067 1 x 10 mL piston nose and O-ring.
