Mount the tubing and the buret tip as follows:
1 Screw the dosing tubing 6.1805.100 (40 cm) on the left-hand side to
Port 1 of the dosing unit.
2 Tighten the connection nipple with the wrench 6.2739.000.
3 Screw the open dosing tip 6.1543.060 or the antidiffusion tip
6.1543.200 onto the dosing tubing.
The link stopper 6.1446.030 included in the scope of delivery can be
used to fix the tip in place in a ground joint opening NS14/15.
4 Insert the buret tip into the storage vessel provided for this purpose.
Details concerning the selection of the buret tip (see Chapter 3.5.3, page

The first-time filling of the dosing unit requires no special measures. Each
Metrohm control device (e.g. Titrando, Titrino or Sample Processor) is
equipped with a PREP/Preparing function with which the filling of the
dosing cylinder and the rinsing of the dosing unit tubing can be readily
accomplished in an automated sequence.
