1 Introduction

1.1 Instrument description

The 869 Compact Sample Changer is a sample changer for titration with a

wide variety of applications. It is the central control instrument in an auto-

mation system that in addition to a titrator, can also include a Dosimat (for

adding auxiliary solutions) and a pump for rinsing and aspirating the sam-

ple vessels.

Specified method runs can be individually parameterized and saved as

sample-specific methods. The methods can be exported to a connected

USB flash drive. This function enables you to copy methods quickly and

easily from one instrument to another.

1.1.1 Instrument components

The 869 Compact Sample Changer has the following components:

￭Turntable

Permanently mounted sample rack with 11 positions for sample beak-

ers and 1 position for a rinsing beaker.

￭Lift with lift head

For two electrodes, one rod stirrer, two dosing tips, one aspiration tip

and three rinsing nozzles.

￭Stirrer connector

For one rod stirrer with propeller stirrer.

￭USB (OTG) connector

The 6.2151.100 adapter can be used to connect, for example, a printer

or a USB flash drive (for system backup or method export).

￭Remote connector

For connecting a titrator, a Dosimat, and/or an 843 Pump Station.

1.1.2 Intended use

The 869 Compact Sample Changer is designed for usage as an automa-

tion system in analytical laboratories. It is not suitable for usage in bio-

chemical, biological or medical environments in its basic equipment ver-

sion.
