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 feature of the device is the tank manufactured from acrylic glass. Thereby the etching process can be observed at any time.

During the etching process, tiny air bubbles will be fed into the etching fluid. This is a diaphragm pump and an aeration frame with air curtain tube in the bottom of the device is used.

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.
