Kinsten etch tanks are suitable for etching single and double sided PCBs with most etchants. The thin, vertical standing, design uses minimal etchant. The tanks have graduations for easy measurement.

The Kinsten ET20 tank can etch a maximum PCB size of 23×30cm without heater, or 20×30cm with heater. Use with 2000cc minimum, 2300cc maximum liquid. 
(1000cc = 1 litre)

Etch tanks include three clips to suspend the PCB in the liquid etchant, and a thermometer to monitor liquid temperature.

Options include an air pump to bubble agitate the etchant, and heater to maintain optimal etchant temperature, for more efficient etching.

The ET etch kits include etch tank, air pump, heater and thermometer.
