The SpeedBrite 300SB converts your ultrasonic to a super-powerful combo cleaner!

An ultrasonic with heat is great for removing dirt build-up from tight crevices. Ionic cleaners are the fastest way to remove tarnish from metal. The new 300SB adapter combines ultrasonic and ionic power for a more complete and efficient cleaning system.

Use alone or in conjunction with the ultrasonic.

Adapter easily hangs on the side of nearly any ultrasonic on the market, any size tank, and attaches to the included ring hanger.

One year warranty and free tech support.
