The TitraLab®
Concept
Why do we use titration?
It can be essential to know the exact concentration of a
chemical species or molecule in raw materials or products
in order to ensure the efficiency of a manufacturing process
and the quality of the finished goods. Among the many
techniques available, titration is commonly selected because
of its ease of implementation, cost-effectiveness and
accuracy. As it is well suited to a wide range of applications
and concentrations, it has been adopted as a standard
technique in a variety of industries such as water quality,
pharmaceuticals, petrochemicals and food and beverage.
Whatever the application, productivity and traceability are
of paramount importance. Automation of routine titration
increases analysis throughput and secures the consistent
quality of results and integrated documentation functions
ensure compliance with Good Laboratory Practice.

Radiometer Analytical’s TitraLab range is designed to satisfy
this demand with systems ranging from simple routine titrators
for basic applications to high-performance customised
set-ups with sample changers and dedicated software.

SAC850 and SAC950
Sample Changers
- Effortless sample handling...
The obvious choice for your laboratory
Radiometer Analytical sample changers are capable of handling
multiple combinations of titrations, direct pH, ion and conductivity measurements fast and efficiently. Connect to a TitraLab
titration workstation or a direct measurement meter with or
without PC software selected from our complete laboratory
product range and your laboratory will virtually run itself!
Compact and Adaptable
The SAC850 and SAC950 are compatible with a wide selection of
removable sample trays, making them remarkably space-efficient. No
special beakers are required; they accept standard glass and disposable
beakers with volumes ranging from 25 to 400 ml.
There is no need to programme the sample changer each time a new type of sample
tray is used as it is instantly identified by a wireless RFID tag containing all relevant
geometrical characteristics. High rotation speed and smooth turntable movements
allow fast and safe navigation between samples.
16
Flexible and Programmable
Sample preparation sequences can be programmed from TitraMaster 85 Titration PC Software with
specific macro commands to fit your requirements. User-defined sample preparation sequences offer
all the benefits of full automation. You can activate the Start/Stop stirring function or the pumps for
a chosen duration, wait or send a TTL command to/from an external device and wait for a specified
temperature to be reached.
Quick and Efficient
The powerful Dynamic Spray Rinse feature and high flow-rate pumps ensure quick and thorough
cleaning with no risk of cross contamination between samples, helping you achieve greater accuracy
and reproducibility, irrespective of the number of samples per cycle. Efficient rinsing is obtained
thanks to repeated vertical movements of the head combined with the mechanical action of the
sprays.
Rinsing liquid is sprayed from all directions over the entire height of the electrodes and tips while the
waste pump empties beakers and evacuates rinse waste. This dynamic rinsing performed directly over
the analysed beaker reduces the total duration of the sample changer cycle multiplying the number
of samples analysed per day.
Safe and Clean
Our unique bayonet concept keeps electrodes and delivery tips securely in place. This ensures reproducible results and allows you to use any combination of electrodes, conductivity cells, temperature
sensors or delivery tubes for your analyses. Tubes and cables can be inserted or removed in no time
and are held in position in a cable carrier for maximum convenience. Reagent addition tubes are
permanently visible for inspection.
The SAC950 includes 3 external beaker positions (2 for dip rinsing/conditioning and 1 for parking) allowing you to exploit the full beaker capacity of the tray and increase the number of samples
analysed per cycle.

Use as a stand-alone dosing unit
The ABU52 can be operated manually by simply connecting a standard PC keyboard. Just fit the right
electrode and the ABU52 becomes a versatile manual titration unit. mV/pH readings are shown on
the large screen for each titrant increment dispensed along with a live titration curve. Graphic tools
enable you to determine the location of your equivalence point(s) manually in order to calculate the
final result.
