Hi

Whats wrong with glas container?
I made a "small" etch tank outoff stainless steel and glass, air inlett at the bottom and heater 1" above so the heated water is circulated properly. Heater is a 1kW heater controlled by pt100 and trip amplifier.

But you are right, if you are not carefull it be a mess quite quickly, it depends how much you like to spend and do yourself.

I only use sodium persulphate but since the glas and steel can sustain acid I can change that later on if I like. I can get the sodium persulphate for free and it is not so messy to mix as pure acid.

Perhaps you mean spray etchers, I thought of that but could not find a cheap pump for it.

Was using the cheap ones...look like a thin aquarium (o;

Many times the foam tube at the bottom gets stuck and did break many times when trying to clean it...also the rubber bands break often when readjusting the foam tubes...and lots of dirt around the table caused by the bubbling.

Anyone used those at:



Look more cleaner for operating...
