1 Introduction
The present tutorial helps you to get acquainted with the operation of the
900 Touch Control. You will be guided step by step through the most
important dialog pages by using a simple pH titration as an example.
Thereby you will learn how to efficiently operate and use the 900 Touch
Control.
1.1 Structure of the tutorial
￭Setup
Preparing the titration system.
￭Basics – simple acid-base titration
Loading and carrying out methods, displaying results.
￭Additional functions – creating methods, statistics etc.
Optimizing titration parameters, calculating statistics, efficiently using
the sample table.
￭User administration
User list, login with USB flash drive or password.
Detailed information on the functioning and operation of the Titrando sys-
tem can be found in the online help and the corresponding manuals:
￭Manual for the Titrando
￭Manual for the 900 Touch Control
￭Manual for the exchange unit
￭Manual for the 800 Dosino or the dosing unit
1.2 Symbols and conventions
The following symbols and formatting may appear in this documentation:

2 Setup and configuration
2.1 Setting up the instruments
What you will need:
￭A 900 Touch Control
￭A Titrando with internal dosing drive and an 806 Exchange Unit
or
A Titrando without internal dosing drive, with an 800 Dosino and an
807 Dosing Unit
￭A magnetic stirrer (801 Stirrer), an 803 Ti Stand or an 804 Ti Stand with
propeller stirrer (802 Stirrer)
￭Some sample vessels
￭A pH electrode with connection cable
￭Possibly an additional 805 Dosimat with an exchange unit (e.g. 20 mL)
or
Possibly an additional 800 Dosino (dosing drive) with a dosing unit (e.g.
20 mL)
￭A bottle with titrant (e.g. caustic soda c(NaOH)=0.1 mol/L)
￭Possibly a printer with connecting cable
￭Possibly a balance with connecting cable
￭Deionized water (carbonate-free)
The manual for the Titrando describes in detail how to install the accesso-
ries. A few notes about this:
Titrant
During this tutorial you will carry out simple titrations. Select an acid or
base as titrant.
Sensor
Use a pH glass electrode for the acid-base titration. Do not forget to plug
the electrode cable into the connector Ind. on the rear of the instrument.
Stirrer
Connect the magnetic stirrer (801 Stirrer) on the rear of the instrument
to the connector MSB 1.
Printer
Select a printer with a USB connector. Use a commercially available USB
cable to connect the printer.

4￭￭￭￭￭￭￭￭ 900 Touch Control
Balance
If you connect a balance to the 900 Touch Control, you can transfer the
sample size per push-button from the balance to the titrator.
800 Dosino
In case you would like to automatically add an auxiliary solution to the
sample before the titration, you will also need a Dosino. Connect it to the
connector MSB 2 on the Titrando.
Samples and sample vessels
You can use sample beakers of any size. Use an acid or base as sample,
which can be titrated with the selected titrant.
Please note that the stirrer has to be connected to the connector MSB 1
of the Titrando for the following example methods. If you use a Titrando
without internal dosing drive, then you must connect the external dosing
device (here: Dosino) to the MSB connector of the stirrer. This way it will
be controlled like an internal dosing drive of the Titrando, i.e. as dosing
device 1.
