Connecting the Tubing

Tubing connectors should be hand-tightened, tools should not be used as their use will damage the connector’s thread.

Single-syringe Model

Valve Inlet Tubing

A length of Fluoride Ethylene Propylene (FEP) tubing, supplied with the 402, is used to connect the inlet port to the solvent reservoir. Screw the connector into the inlet port (left-hand) of the valve and put the other end into the reservoir. A bottle clip is provided to hold the tubing securely in the reservoir (see opposite Figure).

An alternative tubing, fitted with a connector at one end and a 20 µm filter at the other, is available as an accessory (reference 3645357).

Waste Tubing

Connect a suitable length of tubing from the waste outlet of the valve to a suitable receptacle. The valve releases liquid through the waste outlet if the pressure inside the valve is too high. For the pressure limits of the valve, refer to Appendix C, Technical Data.

Transfer Tubing (Probe)

This tubing (FEP) allows the transfer of samples aspirated from the probe and prevents the contami- nation of the syringe(s). The size of transfer tubing is chosen as a function of the volumes of samples, reagents, and air gaps that have to be handled via the probe. The total volume transferred must be less than the volume of the transfer tubing.

The transfer tubing connects the outlet port (right- hand) of the valve to the probe. A 2 mL tapered tubing is supplied as standard; 1 mL, 5 mL, and 10 mL are available as additional accessories.

Self-adhesive clips are provided for holding the transfer tubing securely against the side of the 402.

The 1 mL transfer tubing is recommended for trans- ferring volumes smaller than 1 mL. To avoid move- ments of the tubing that could affect the precision, the 5 mL and 10 mL transfer tubings are rolled and held by magnets on the left-side of the 402.
