Wiggens Titrator CAT1-1/ CAT2-1


CAT Automatic Titrator has been designed to simply and precisely perform the widest range of potentiometric titrations. has always been the first choice if you were looking for a very easy-to-use automatic titrator for any application. A special training or a deeper knowledge of automatic titration was not necessary to get precise and quick results. That and much more is exactly what the new generation of FLASH stands for.

Main features


Bright display with strong illumination can be viewed easily from a long distance.


Compact instrument and can be both upgraded and configured to satisfy the everchanging laboratory needs.


The wide color touch screen display contains all the messages and the icons that make Flash extremely easy to use. The titrator guides the user in each programming phase, analysis, and data interpretation.

Modular design

Up to 2 burettes and 3 peristaltic pumps, operated together or separately, every stage of the titration process can be made truly automatic.

Peripheral modules

Single analysis stand, 16 positions autosampler, 35 positions autosampler, Printer, and Software.


Default methods, Method template make to quickly edit and start your experiments.

Auto-level adjuster

Designed to optimize the procedure of samples auto level, in order to speed up the sample preparation.

Auto-degassing system

Nitrogen valve for sample degassing.

Titration curve

During the titration process, the graphic trend is displayed in real-time so that the operator is immediately informed about the analysis trend.


pH electrode calibration report, Standard titration report, and Sample titration report.


Data management software via external PC

Switch on. And off you go.

Intelligent operating concept. Ready for operation with just a few quick and easy steps.
