10-port valve
The 10-port valve is used for sample preparation. For this, the central posi-
tion
can be connected to the 10 other positions, one after the
other, by means of the selector
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
