Professional grade ultrasonic cleaner with heater and digital controls. 2.6 Qt or 2.5 L tank capacity. Powerful industrial grade ultrasonic transducer. It can be used to clean jewelry, optical glasses, brass cases, automotive parts, etc. A full size plastic basket is included. It's much easier to use compared to a plastic tray which is typically included in the other listings. Warning: Do not use corrosive solutions including liquid bleach such as Clorox in the stainless tank! It's corrosive towards stainless steel and will create pin holes quickly with an ultrasonic cleaner. Do not use corrosive solvents.
