H2O + H2O2 + H2SO4 = (Piranha solution / Caro's acid)

Since years Puerstinger deliver Mix- and Dilution system for aggressive acids and other media. In this compact Mix system for Caro’s acid are following media according on an exact recipe mixed, Di-water, Hydrogen Peroxide and Sulfluric Acid.  Regarding the exothermic reaction the bath temperature increases and will be cooled down automatically to the specified set point (Degree Celsius exactly). After the desired temperature of the Dilution has been reached the set point, the Dilution will be transferred to the Buffer tank.  The supply from the Buffer tank to the tool is done via a with a pneumatic operated diaphragm pump.
