Connections on the bottoms of the 50 mL Dosing Unit
ƒ Port 1 is used for emptying the Dosing Unit 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 used for sample transfer to the IC system. The transition from M6 to the IC screw size
(1/16 in.) is achieved with the 6.2744.080 adapter.
ƒ Port 4 is used for the 50 mL Dosing Unit. 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. The 60 cm M6 FEP-tubing can be directly connected to the Luer/M6 adapter to realize
«liquid handling» to the external cell.
Once the tubing connections have been made, the Dosing Units are attached to the Dosino holder
(6.2055.100) with the screw attachment and the distance ring of the Connecting Set for Dosing Unit
(6.5620.000).
