After assembling the probe, the other end of the tubing is installed by screwing the connector into the right-hand port of the valve. When you use Gilson Diamond Tips, the special non-tapered tubing, included in the kit, must be fitted.

Connecting the

Valve Inlet Tubing

A length of Fluoride Ethylene Propyl- ene (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.

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).

Valve Waste Tubing

Connect the length of tubing (supplied as standard) to the waste outlet of the valve, and put the other end into the waste or any other suitable receptacle. The valve releases liquid through the waste outlet, if the pressure inside the valve is too high (see Appendix C, Technical Data).

Connection Tubing (Valve to Tee-junction)

This tubing has connectors at both ends and is used to connect from the valve outlet port (right-hand) to the Tee-junction inlet port (left-hand). It is made of FEP and has the following dimensions: 70 x 3 x 2 mm. It is autoclavable (20 min. at 0.1 MPa, 121 °C).

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.
