Purge and bridge tubes for corrosion cells

Bridge tubes are used to avoid direct contact of the reference electrode with the electrolyte. Also it ensures a very short distance between the reference and the working electrode, minimizing the ohmic drop. Purge tubes are used when the electrolyte needs to be oxygen-free. Usually one uses an inert gas such as argon or nitrogen to purge the solution and also create an oxygen-free environment on top of the electrolyte, preventing air to enter the cell.. Two bridge tubes are available, both for the flat cell and the corrosion cell: one can accommodate 6 and 8 mm diameter reference electrodes. Two purge tubes are available for both the flat and standard corrosion cell: one has a single tube and the other is double-walled to allow the user to blanket the electrolyte.
