{"product_id":"the-small-etch-cell","title":"The Small Etch Cell","description":"\u003cp\u003eOne of the most common applications of an electrochemical etching cell is the preparation of a Nanocrystalline Porous Silicon Layer on a single crystal Si wafer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication note\u003c\/strong\u003e\u003cbr\u003eTo perform an electrochemical process, a square conducting sample is placed on the cell base, using a piece of aluminum foil as a back contact. 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. \u003cspan\u003eSee the assembly demonstration \u003c\/span\u003ehere\u003cspan\u003e.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003cbr\u003enominal exposure area: 0.21 cm\u003csup\u003e2\u003c\/sup\u003e\u003cbr\u003eelectrolyte volume: 2.2 mL\u003cbr\u003eminimum sample size: 12 mm x 12 mm\u003cbr\u003emaximum sample width: 31 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: 100 g\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct includes\u003cbr\u003e\u003c\/strong\u003e1 x cell base - 0058CPEMASM\u003cbr\u003e1 x cell top - 0059CPEMASM\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\u003cbr\u003eGlassy (vitreous) carbon substrates – GC 25\/25\/custom\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.
