1 Introduction
The 800 Dosino is a versatile dosing drive which can be used with a number of different Metrohm dosing devices or titrators (e.g. Titrando). The
800 Dosino and the 807 Dosing Unit associated with it are suitable as a
buret for simple dosings, titrations and for complex automation and liquid
handling tasks such as sample transfers or pipetting.
1.1 Instrument description
￭ Thanks to various 807 Dosing Units with 2, 5, 10, 20 or 50 mL dosing
cylinders, the 800 Dosino is suitable for flexible use as a buret (dosing
drive and dosing unit) and for adaptation to a number of different
kinds of applications. Older dosing units (without data chip) can also
be used.
￭ Reagent changes with the lowest possible loss of reagent are now pos-
sible, due to the fact that the design of the dosing unit has been optimized to a minimum dead volume.
￭ The 800 Dosino with the dosing unit is attached directly to the reagent
bottle. A selection of thread adapters ensures optimum seating on the
various bottle types and threads. This type of assembly results in a very
space-saving installation. The dosing drive cannot be damaged by
escaping fluid because it is placed above the reagent.
￭ In the event of frequent changes of reagent, the dosing units can
remain mounted on the reagent bottle. The dosing drive can be readily
removed and set up on the next dosing unit in one manual step.

3.2 Setting up the Dosino and the dosing unit
3.2.1 Dosino with Titrando
When the 800 Dosino is used together with an 807 Dosing Unit as a
titrating buret with a Titrando, two bottles (with titrant or auxiliary
reagents) can be placed on the Titrando with dosing unit and Dosino
mounted (see Figure 2, page 8). Additional titrants or auxiliary
reagents can be given stable storage in practical bottle holders (see Figure
3, page 8).

3.2.2 Dosino with bottle holder
￭ If the 800 Dosino is utilized as a dosing drive for adding auxiliary
reagents, e.g. in operations with the Titrando, then the practical and
stable 6.2061.010 bottle holder with storage vessel for buret tips can
be used.
￭ The bottle holder can be adjusted for various bottle sizes with the aid
of a 6.2043.005 retaining clip.
