Malvern Nano ZS zeta and particle sizer

Two-angle particle and molecular size analyzer for the enhanced detection of aggregates and measurement of small or dilute samples, and samples at very low or high concentration using dynamic light scattering. The ZSP also incorporates a zeta potential analyzer that uses electrophoretic light scattering for particles, molecules and surfaces, and a molecular weight analyzer using static light scattering.

Gravimetric instrument for characterization of absorbents

The gravimetric instrument is capable of measuring weight increase and decrease due to ab/desorption within pressure and temperature range of 0 and 50barg and ambient temperature to 100 deg C, respectively. The sensitivity of the gravimetric balance is 0,1μg.

Metrohm Karl Fischer Titrator

This instrument uses coulometric titration to determine trace amounts of water in a sample.


Sealed container that allows us to manipulate objects in a separate atmosphere.

Metrohm Autolab potentiostat/galvanostat instruments

This high-end, high current potentiostat/galvanostat allows for a multitude of electrochemical characterization methods ranging from cyclic voltammetry (CV) to electrochemical impedance spectroscopy (EIS). Additionally, the instrument can be used for electro-deposition.
