The Micro Quik Cell consists of a threaded, two (2) piece body and two 13mm x 1mm silver chloride (AgCl) circular windows of a special design. The windows fit into one portion of the cell and the second portion of the cell is then engaged to form a seal. The cell pathlength can be varied from 0.025mm to 0.05mm by positioning the windows as shown in the diagram. The AgCl windows measure 13mm diameter x 1mm and each contains a 0.025mm circular depression. The rim of the window is flat and the circumference is beveled to ensure proper sealing. AgCl flows slightly under pressure, permitting a tight seal to be formed. Cell comes complete with slide holder, cell body and six AgCl windows with 0.025mm depression.
