This module provides you with optical access to the sensor surface through a sapphire window, enabling experiments with light-induced reactions and combination with live imaging techniques. The compact design of the Explorer chamber enables microscopic analysis of the sensor surface since the unit will fit on most microscope stages. It is an appreciated add-on in fluorescence microscopy applications. The standard configuration includes Viton O-rings, but this can be upgraded to Kalrez to enable work with more harsh chemicals.
