After the screw nipple (6.2730.070) has been screwed into opening 9, the aspiration tip
(6.1543.100) is pushed through it. An FEP-tubing connection (6.1805.060, supplied with 815)
will be connected to the connection set of Dosing Unit port 4 of the 50 mL Dosing Unit.

Connections on the bottom of the 50 mL Dosing Unit
ƒ Port 1 is used for emptying the Dosing Units into the waste canister.
ƒ Port 2 is used by the 50 mL Dosing Unit for aspirating the sample via the titration arm.
ƒ Port 3 is not used in this setup.
ƒ Port 4 is used for realizing the «liquid handling» to the external cell.. This requires a coupling
between Luer and M6: The PEEK connection (6.5620.000) is attached to the Luer connection
on the bottom of the Dosing Unit.
Once the tubing connections have been made, the Dosing Unit is attached to the Dosino holder
(6.2047.010) with the screw attachment and the distance ring of the Connecting Set for Dosing Unit
(6.5620.000).
