Cleaning

The 25 mL syringe is not autoclavable, all of the other size syringes are autoclavable.

Cleaning the Syringe Assembly

You must dismount the syringe and piston assembly from the instrument and then separate the syringe and piston assembly before cleaning or autoclaving them.

1)Dismount the Syringe assembly from the instrument.

2)Undo the piston securing screw to free the piston assembly from the piston operating rod.

3)Lower the piston operating rod; for Gilson soft-ware there is a change syringe program that lowers the piston operating rod - use this software option to lower the piston operating rod away from the syringe piston. Refer to your software User’s Guide for the precise sequence. This allows you to dismount and mount the syringe and valve/Tee assembly without the risk of damaging the syringe.

4)Undo the syringe from the body of the valve or Tee.

5)Remove the piston and syringe assembly from the pump.

6)Pull the piston out of the syringe body. For large syringes; 5, 10 and 25 mL syringes, you must 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.

7)Clean or autoclave the two parts (except the 25 mL syringe).

8)Ensure that the syringe and piston assembly have cooled to room temperature before reas- sembling the syringe and piston. Ensure that the piston and the piston nose are free from dust or contamination before introducing the piston into the syringe. Wet the piston nose (water will suffice) before inserting the piston in the syringe. Insert the piston nose in the syringe body and push the piston into the syringe.

9)Remount the syringe assembly on the valve or Tee. Screw the threaded end of the syringe body into the valve or Tee.

10)Lower the piston so that it comes into contact with the piston holding screw.

11)Tighten the piston holding screw so that the piston assembly is secured against the piston operating rod.
