Electrolytic polishing or chemical etchingSimultaneous two-sided polishingNo induced artifactsEasily adjustable flow rate, jet and specimen positionsReliable, accurate terminationHigh-quality thin foils for TEM Electrolytic thinning of conductive materials is an effective method of quickly producing specimens for transmission electron microscopy (TEM) without any induced artifacts. In the Model 110 Twin-Jet Electropolisher, twin jets simultaneously polish both sides of the sample, creating electron transparent specimens within a few minutes. The electropolisher features easily adjustable electrolyte flow, polishing voltage, termination detection sensitivity, and jet and specimen holder positions.
