3 The Dosino in practice
700 Dosinos can be connected to various control instruments.
They are used as dosing drives which can be operated with differ-
ent 710 Dosing units. The dosing unit forms the buret and is
mounted directly on a reagent bottle or a canister.
Changing a dosing unit (and therefore a reagent) is very easy. The
drive is removed from one dosing unit with a single movement and
attached to the next one. The Dosino remains plugged into the
control instrument.
Before a Dosino buret is used we recommend that the dosing cyl-
inder and the tubing are rinsed through once with reagent solution
in order to ensure that the whole system is bubble-free.
Metrohm instruments possess the comfortable
'PREP' function for
this important preparation step: a complete rinsing cycle is trig-
gered by pressing a key.

If a dosing unit is to be filled with a different reagent then the dos-
ing cylinder and connected tubing are first emptied with the
'EMPTY' function. The dosing unit is then filled by using the
'PREP' function .
