1 Introduction

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.

1.1Instrument 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 possible, 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.

3.1Setting up the instrument

3.1.1Packaging

The instrument is supplied in highly protective special packaging together with the separately packed accessories. Keep this packaging, as only this ensures safe transportation of the instrument.

3.1.2Checks

Immediately after receipt, check whether the shipment has arrived complete and without damage by comparing it with the delivery note.

3.1.3Location

The instrument has been developed for operation indoors and may not be used in explosive environments.

Place the instrument in a location of the laboratory which is suitable for operation, free of vibrations, protected from corrosive atmosphere, and contamination by chemicals.

The instrument should be protected against excessive temperature fluctuations and direct sunlight.

3.2Setting up the Dosino and the dosing unit

3.2.1Dosino 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).

3.2.2Dosino 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.
