Syringes

The 402 Dilutor-Dispenser is supplied without syringes. Order a syringe (or syringes), appropriate to your Method, for your 402 Dilutor-Dispenser. Mount the syringe on the valve or Tee-junction.

Assembling a Syringe

The syringe and its piston are supplied assembled. However, if you remove the syringe from the piston, ensure that the piston and the piston nose are free from dust and contamination before reinserting the piston into the syringe.

Wet the piston nose (with water), insert the piston nose into the syringe body, and then push the piston into the syringe.

Fitting a Syringe

Before fitting one of the smaller syringes (100 µL, 250 µL, 500 µL and 1 mL), prime it manually by placing its open end in the solvent reservoir, then aspirate using the piston. This manual prime is not necessary for the 5 mL, 10 mL and 25 mL syringes.

You must use the keypad software to lower the piston operating rod. You should therefore refer to Chapter 4, which describes the complete procedure for fitting a syringe. When changing a syringe, you should first undo the piston securing-screw in order to free the piston assembly from the piston operating-rod.

The 100 µL, 250 µL and 500 µL syringes are sup- plied with a cover seal to ensure an airtight fit between the syringe and the valve or Tee. Refer to the opposite figure for the correct orientation of the cover seal.

If you change the syringe size, don’t forget to change the declared syringe volume in your soft- ware’s system configuration.
