1 Properties of the TITRONIC
®
universal Piston Burette
1.1 General
The TITRONIC
â â â â
universal Piston Burette which requires just the space of a DIN A4 sheet can be used to
carry out all common titrations, dosing processes as well as incremental dosing in a simple manner.
The accurately functioning dosing system meets the essential precondition for correct titration and dosing.
In addition to the high-precision glass cylinder made of DURAN
â â â â
borosilicate glass, the play-free mo-
tor/spindle system ensures correct dosing, incremental dosing, and titration results.
Incremental dosing offers furthermore the use in balance reactions and as an electronic dropping funnel.
The very simple operator prompting allows you uncomplicated working. The display will ask you to select
the respective function or to set the corresponding parameters. Even during the execution of a function the
burette’s display will keep you at any time informed about its present status.
The two RS-232-C interfaces enable series daisy chaining of more than one TITRONIC
â
â â
â
universal Piston
Burettes for connection to a computer (PC).
The TM 96 Stirrer and the TZ 3665 Stand Rod attach directly to the TITRONIC
â
â â
â
universal Piston Burette.
The electrical contacts (15 V =) connect automatically when the stirrer is being installed. This means that
the electrical power for the TM 96 Stirrer is supplied from the TITRONIC
â â â â
universal Piston Burette.
All parts coming into contact with the titration and dosing solutions are made of chemically resistant mate-
rials. Analysis accuracy is guaranteed by the high-precision glass cylinder and the spindle for the piston
feed. The controlled three/two-way valve, the easy-to-read consumption display with its additional status
messages, the stand/stirrer system, and the practical manual key button make the TITRONIC
â â â â
universal
Piston Burette a device with comfortable use properties.
Within the present operating instructions, the TITRONIC
â
â â
â
universal Piston Burettes with 20 ml or 50 ml
cylinder are collectively referred to as TITRONIC
â
â â
â
universal Piston Burette.
1.2 Dosing and titration solutions
To save titration solution and to render the disposal of the chemicals after the analysis as simple as possi-
ble, we recommend to select any titration-solution consumption between 5 ml and a 15 ml for titration
Solutions to be used:
In practice, any solutions and liquids with the viscosity of < = 10 mm² / s can be used, such as e.g. con-
centrated sulphuric acid. However, chemicals attacking glass, PTFE, or FEP, or which are explosive, such
as hydrofluoric acid, sodium azide, or bromine must not be used! Suspensions with a high solid contents
may block or damage the dosing system.
General rules:
The respectively applicable safety guidelines on handling chemicals are to be observed under all circum-
stances. This applies in particular to inflammable and/or etching liquids.
