ETCHING DEVICE A range of bubble Etch tanks designed to be used in laboratory and small batch production for producing printed circuit boards as well as for etching metal foils used in model making. Special features of the devices are that the tanks are manufactured from acrylic glass. Thereby the etching process can be observed at any time. During the etching process, tiny air bubbles are fed into the etching fluid. This is a diaphragm pump with an aeration frame with an air curtain tube in the bottom of the tank. The etching tanks include an adjustable glass heater for heating up the etching solution up to 45°C. There is an adjustable PCB-holder for carrying the printed circuit boards during etching and a thermometer. PA104 Shipping Dimensions 46cm x 62cm x 20cm
