Boost your research

 

Temperature is the 5th degree of freedom or the “5th dimension of electrochemistry”. In addition to potential, current, time and concentration, temperature can be experimentally controlled to change a reaction’s outcome, rate, etc. Direct control of this 5th dimension can allow you to boost your current research or even open up completely novel applications in Analytics.

 

  • Description

    The ThermaLab can be used to improve both synthesis and analysis. In addition to augmenting reaction yield, it increases analysis sensitivity and selectivity by accelerating adsorption and synthesis processes directly at the point of interest. Thermal effects control the velocity and the direction of reactions by reducing production and side products and boosting conversion rates. New electrochemical methods provide promising applications in science and industry, such as mass transport directly at electrodes without mechanical assistance.

  • Applications

    The ThermaLab technology can apply a precisely defined temperature at the place of reaction while the reaction is running. This offers applications in the fields of:

    - analysis of DNA-strands (e.g. SNP-detection, hybridisations)
    - analysis of trace heavy metals  (e.g. copper, lead)
    - using aptamer technologies to detect specific biomolecules and improve analysis signals
