Quester Q10

Quester is a highly innovative, unique and low cost instrument to characterize small volumes (in microliters) of reagents in liquid state. The instrument employs mechanically vibrating quartz probes which are immersed into a droplet, placed in an open space or a closed chamber.

Droplet Characterization

Quester is ideal to characterize individual droplets of reagents such as blood, drug formulation etc.

Low Cost

Quester and its consumables (quartz probes) are low cost, highly reliable and well tested solution for analytical measurements.


Multiple types of measurements can be performed simultaneously.


Quester can be customized with features such as heating/cooling module, infrared excitation etc.
