The setup is sealed by an O-ring to prevent electrolyte leakage. The cell is filled with an electrolyte, and the wire electrode is immersed in the solution as a counter electrode. An electric current is passed between the aluminum back contact and the wire electrode for a certain amount of time. After the process, the cell elements should be washed several times with ethanol and dried under the nitrogen flow. See the assembly demonstration here.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003cbr\u003enominal exposure area: 8.6 cm\u003csup\u003e2\u003c\/sup\u003e\u003cbr\u003eelectrolyte volume: 15 mL\u003cbr\u003eminimum sample size: 38 mm x 38 mm\u003cbr\u003emaximum sample width: 45 mm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIntrastat data\u003c\/strong\u003e\u003cbr\u003eHS Code: 85433070\u003cbr\u003eCountry of Origin: Sweden\u003cbr\u003eNET weight: 300 g\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct includes\u003cbr\u003e\u003c\/strong\u003e1 x cell base - 0055CPEMASM\u003cbr\u003e1 x cell top - 0056CPEMASM\u003cbr\u003e1 x set of screws - 0057PNYCM\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRelated products\u003c\/strong\u003e\u003cbr\u003eSpiral Metal Wire Electrode for Etch Cell\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #38761d;\"\u003eThis etch cell has been developed based on a design of Prof. Dr. Michael J.
