Syringes

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.
