1 Introduction
The 805 Dosimat is a versatile dosing drive which can be used with a number
of different Metrohm devices (e.g. Titrando or sample changer). The 805
Dosimat and the corresponding 806 Exchange Unit are suitable as a buret
not only for simply dosing auxiliary solutions but also for titrations.
1.1 Instrument description
Thanks to various 806 Exchange Units with 1, 5, 10, 20 or 50 mL dosing
cylinders, the 805 Dosimat is suitable for flexible use as a buret (dosing unit
and drive). Older exchange units (without data chip) can also be used.
The exchange units can be set up on the Dosimat and also removed again
in one easy manual step.
