Our benefits


Automatic process operated via specialized remote control software.

Compact design

Our compact design allows to install the unit in each lab.                                                                           


All in One – fast screening and up to TRL 5 tests on the same unit.                             


Easy use and maintenance. High reproducibility of the results.
