872 Extension Module – Liquid handling
3 Functioning
3.1 10-port valve
The 10-port valve is used for sample preparation. For this, the central posi-
tion (3-11) can be connected to the 10 other positions, one after the
other, by means of the selector (3-13).
The transfer tubing is connected to the central position. Liquids can be
aspirated into the transfer tubing by one of the 10 positions with the aid
of a Dosino and then transported to any other position by reversing the
flow.
The following illustration shows a 10-port valve with a possible utilization
of the positions:
