1.3 Metrohm 700/800 Dosinos and Dosing Units
The Metrohm 800 Dosino is a versatile dosing drive which can be used with
various Metrohm dosing or titrating instruments (e.g. 808 or 809 Titrando). The
800 Dosino and its associated 807 Dosing unit are suitable for use as a buret,
not just for simple dosing tasks and titrations, etc. but also for complex auto-
mation and liquid handling applications, such as sample transfer or pipetting.

The 800 Dosino together with an 807 Dosing unit (available with 2, 5, 10, 20 or

handling applications.

nected to the necessary dosing inlets and outlets. Four ports are available.

vided for it in the centering tube of the dosing.
