Ventacon’s Series E Electrochemical Cells consist of a specially selected borosilicate glass body carrying a platinum ring secondary electrode and a capillary connected side pocket for a standard electrode. The working electrode consists of a high purity pellet held in a polymer sleeve and electrically connected to a rod passing down its axis. The whole cell is firmly mounted in a metal cradle that fits into the Sample area of your Raman Instrument. In operation, the cell is filled with electrolyte and connected by cables passing through the access holes in the sample compartment, to a standard electrochemical potentiostatic control unit†. The working electrode can be moved towards the front optically flat window or back close to the secondary electrode. All Ventacon cells operate within the sample chamber with the lid closed. See Safe Operation page for details of methods of communication between the sample area and the laboratory. The cells are fitted with detachable and replaceable windows which can be supplied in borosilicate glass or silica. Silica windows are essential if you plan to use 760nm excitation as borosilicate weakly fluoresces. Note: These cells MUST be operated with the window
held vertically. If you plan to use them on a microscope based instrument
you may need to purchase a system to allow horizontal laser operation.
