1. Assembly
Use the ECO titration equipment together with the 703 Ti Stand. It
is best to feed the 703 Ti Stand with a separate 11 V power
adapter (and not directly from the Titrator).
Ordering numbers for the power adapter:
220...240 V 6.2117.030
110...117 V 6.2119.030
1.1 Assembly for KF titrations
see picture on the front page.
1. Fix titration vessel on the stand rod.
2. Set the 6.2740.030 rinsing nozzle into the left rear aperture:
Put 6.2730.030 nipple, then E.301.0022 O-ring onto the
rinsing nozzle and screw it into the aperture.
3. Cut 2 cm of 6.1543.120 aspirating tip and place it in the right

and 6.2709.090 stopper.
5. Screw 6.2730.070 stopper into the left aperture and insert
6.0338.100 KF electrode without O-ring.
6. Fill drying tube with drying agent (e.g. molecular sieve, or-
dering number 6.2811.000) and screw it into the middle ap-
erture using 6.2730.070 stopper.
7. Set 6.2730.020 septum stopper into the middle aperture in
the front.
