The module is tubeless with the lowest possible sample volume requirement. You can directly pipette a minimal amount of liquid to cover the sensor. This module will provide for evaporation studies, external triggered reactions such as photo induced and chemically triggered reactions.
QSense Open module comes with a lid to avoid evaporation of samples and to improve measurement stability. The standard configuration includes Viton O-rings, but this can be upgraded to Kalrez to enable work with more harsh chemicals.
