4.7 Pipetting with the Swing Head
If you have connected the 759 swing head with transfer head to
tower 1 of the sample changer instead of a conventional titration
head, you can pipette, dilute and titrate with the sampler changer.
This allows up to 126 samples to be processed in one series.
4.7.1 Setting up the System
To pipette with the 730 sample changer you will need the model
with 2 towers and 4 pumps (2.730.0120). The swing head with
transfer head is connected to tower 1 (see page 42), and a macro-
titration head (6.1458.010) is connected to tower 2. A 700 Dosino
for pipetting the sample solution from the sample vessels into the
larger titration vessel is connected via the external bus interface
and the 729 Dosimat interface. More Dosinos can be connected
via the Dosimat Interface in order to add auxiliary solutions to the
titration vessel.
