The three 60 cm FEP tubing connections (6.1850.060, supplied with 815) are used to connect
membrane pump 1 of the 815 and the three rinsing nozzles (6.2740.020, supplied with 815) to
openings 2, 5 and 7 of the external cell (see page 7).
The 60 cm M8 PTFE tubing connection (6.1805.510, supplied with 815) is used to connect
membrane pump 2 of the 815 and the M8 PTFE aspiration tip (6.1543.170, supplied with 815) to
opening 1 of the external cell (see page 7).
The aspiration tip (6.1543.080) is attached by a stopper (6.2730.030) to the titration head
(6.1462.070).
The 80 cm FEP tubing connection (6.1850.110, supplied with 815) is used to connect the
aspiration tip (6.1543.080) at the titration head (6.1462.070) and port 2 of the 50 mL Dosing Unit.
The three 40 cm FEP tubing connection (6.1850.100, supplied with 807) are used to connect port 1
of the 10 mL (EDTA) and the two 20 mL Dosing Units (HCl / Auxiliary complexing solution) with the
three connectors of the 3-way stopper at opening 6 of the external cell (see page 7).
The 60 cm FEP tubing connection (6.1850.060) is used to connect port 4 of the 50 mL Dosing Unit
and the buret tip (6.1543.200, supplied with 807) in opening 3 of the external cell (see page 7)..
A suitable length of the 0.97 mm PTFE capillary (6.1803.020, supplied with 861) is used to connect
port 3 of the 50 mL Dosing Units (using the screws 6.2744.080 and 6.2744.070) and the injection
valves of the 861 Advanced Compact IC (position 1).
The four 150 cm FEP tubing connections (6.1805.030) are connected to port 1 of the 50 mL
Dosing Units, as well as port 3 of the two 20 mL and the 10 mL Dosing Units; all four tubing
connections are then connected to the 10 L PE waste canister (6.1621.000).
