Features

The materials that come in contact with media (PTFE, PFA, FEP, borosilicate glass and platinum-iridium) are resistant to most acids, bases, and solvents
GENIUS is equipped with a positive displacement piston and a fluoroplastic (PFA) sealing lip on the cylinder wall
The latter acts like a windscreen wiper to prevent crystal build-up on the cylinder wall from readily crystallisable media
The glass cylinder is also coated with a plastic material that reduces the risk of splashes should breakage occur
The telescopic filling tube can be adjusted smoothly to different bottle heights
GENIUS is equipped with our patented recirculation valve (EP 542 241) that reduces reagent loss when ventilated
The simple-to-use calibration function of the GENIUS helps to meet all of the requirements of testing-apparatus monitoring, with the minimum of downtime
GENIUS is completely autoclavable at 121 °C (2 bar) according to DIN EN 285, and are DE-M marked
