6.2 Connecting Coulometer to Dosino
Automatic reagent exchange is possible with the Dosino.
The inquiry
reagent change
under <CONFIG>,
>monitoring
must be set to
auto
or "man.".
The key <EXCH> is then used to carry out a reagent exchange.
With reagent change

The 2.700.0020 Dosino can be connected directly. If you want to connect a 2.700.0010
Dosino then you require the 6.2134.020 adapter cable.
For aspiration it is an advantage to use the 6.5617.000 aspiration equipment (including
50 ml dosing unit; order Dosino separately).
For aspirating oily samples, where only the sample is to be aspirated and not the whole
reagent, a 20 ml dosing unit or, for very viscous samples, a 10 ml cylinder should be
used; see page 146ff for accessories.
6.2.1 Setup with aspiration equipment
1. Screw 6.1829.010 tube into the threaded opening below the dosing unit. It may be
necessary to cut the tube to the correct length.
2. Screw the dosing unit onto the reagent bottle and insert the reagent bottle from above
at an angle into the bottle holder. Fill the small adsorber tube with molecular sieve and
attach it to the dosing unit. Place the Dosino on the dosing unit.
