The E4 chamber platform has a modular design. Each sensor is fixed in flow modules that can be removed separately for easy cleaning in e.g. ulstrasound bath. Any serial or parallell configuration can be used for measurements and it is possible to start or stop any sensor position individually. When using the optional electrochemistry cell, one sensor flow module is removed and replaced by the electrochemistry cell.
Each flow module has an inlet and an outlet. The flow solution is new; the liquid enters from the side of the crystal. Temperature stabilisation is quick and accurate.
